As older substations are modernized or new substations are built, more device integration capability and less local I/O will be required. We support all applications with highly reliable, technically advanced client/server, peer–to–peer distributed multiple 32–bit microprocessor technology. Incorporating an embedded Linux® operating system that is fully secured (with no user accessibility) provides a stable platform for all distributed microprocessor nodes in each model. Our integration of IEDs is completely vendor-transparent. And anyone with Windows® experience will find NTX Explorer Configuration and Monitor tools very intuitive. It’s as close to plug–and–play as you can get.

The NTX series of intelligent automation controllers are available in pole-top and substation models. All NTX series models can be configured with high–speed isolated RS–232 or RS–485 serial and 10/100 Base T DNP3 over TCP/IP or UDP Ethernet ports, as well as serial ports supporting most popular legacy protocols. The NTX series also incorporates both serial and TCP/IP or UDP Modbus RTU protocol. Both serial and TCP/IP DNP3 and Modbus RTU protocol emulations are configurable as a client, a server, or multiples of both.

NTX-20

The NTX-20 Controller

Read More

The NTX-20 controller is an economical solution for feeder automation where Ethernet and/or serial connectivity is desired. Combining both Ethernet and serial connectivity, master gateway, IED gateway, router, internal GPS precision time reference interface, binary inputs, and power supply functions in a single–package module, the NTX-20 controller interfaces with distribution line switches, capacitor banks, transformers, distributed substation breaker bays, water pumps, valve control devices, etc., to provide low–cost automation with the highest reliability possible.

NTX-200

The NTX-200 Substation Controller

Read More

The NTX-200 Substation Controller, smallest of our NTX Series modular substation system designs, incorporates complete substation management functionality. It also adds the ability to interface to a large amount of data from IEDs and to a small to medium amount of locally-wired data acquisition and control devices in the substation. The NTX-200 utilizes a client/server design. Throughout the NTX-200, servers (such as NTX Gateway to IEDs) produce data, and clients (such as the NTX gateway supplying the virtual databases to the master) receive data. It can also transmit many selected subsets of this data to one or more master stations in the master’s native protocol. Local I/O can also be configured in the three motherboard slots available.

NTX-220

The NTX-220 Substation Controller

Read More

The NTX-220 Substation Controller, the mid-size version of the ACS NTX series substation systems, provides complete substation management functionality. It also adds the ability to interface to a very large amount of data from integrated IEDs, and to a medium to large amount of data from hardwired local I/O devices in the substation. The NTX-220 is designed with multiple 32-bit CPUs operating within a client/server architecture. NTX-220 clients (such as the NTX gateway to IEDs) provide data that is received and processed at the server level in the NTX master gateway supplying the virtual databases to the master. Multiple user-defined subsets of this data can also be transmitted to one or more master stations in the master’s native protocol. A medium amount of local analog and digital inputs can be configured in the six input module motherboard slots available. With the addition of an external expansion card file, these inputs are expandable to the maximum of 256 inputs per local interface node. Control relay outputs are also expandable to 256 relay outputs per control system node, utilizing externally mounted control relay modules with varying voltage and current contact ratings available.

NTX-240

The NTX-240 Substation Controller

Read More

The NTX-240 Substation Controller, another mid-size version of the ACS NTX series substation systems, provides complete substation management functionality. It also adds the ability to interface to a large amount of data from IEDs and to upgrade legacy RTUs interfacing to a medium to large amount of locally-wired I/O devices in the substation. It does not provide any local I/O slots, and is primarily designed to upgrade existing legacy ACS and 2nd source RTUs.

NTX-260

The NTX-260 Substation Controller

Read More

The NTX-260 Substation Controller is the top-of-the-line of our NTX Series substation system designs. It incorporates complete substation management functionality for extra-large data concentration and protocol translation, while supporting a very large amount of local I/O for full integration of old and new substation designs.

Legacy RTU Upgrades

Legacy Interface Upgrades

Read More

The key to the vast savings in time and money lies in our upgrade approach that allows you to leave the local I/O terminations and original field I/O wiring in place. If any of the I/O interfaces are active PCB modules that are unreliable or not adaptable to an NTX series interface, we may be able to replace the original vendor’s I/O terminations with form and fit blank termination boards that have the same terminal block layout.

NTX-U20 (GE D20 Upgrade)

(ACS) NTX-U20

Read More

The Advanced Control Systems (ACS) NTX-U20 is a cost-effective and feature-rich upgrade solution for GE D20 I/O peripheral panels. The NTX-U20 mounts directly to the existing WESTERM termination boards, eliminating the need to disturb or replace any of the existing field wiring.

NTX-U57 Controller

(ACS) NTX-U57

Read More

The Advanced Control Systems (ACS) NTX-U57 is a cost effective and feature-rich upgrade solution for L&G/Siemens TG5700 RTU & I/O subsystems. The NTX-U57 replaces the original TG5700 Controller Card piggy-back mounted on the original Termination Card (for each I/O subsystem type other than SBO Control), eliminating the need to disturb or replace any of the existing field wiring. For the utility, this means up to 60% cost savings over a traditional RTU replacement, since the work required to reproduce drawings, re-cable, and do extensive point checkout is vastly reduced. The original TG5700 Station Manager or Supervisor Module host can be replaced with a NTX series Substation Controller, or any substation system that supports DNP/IP.

NTX Explorer Software

NTX Explorer and Monitor

Read More

The NTX Explorer and Monitor programs are installed on a PC the Microsoft® Windows® XP and Windows 7 operating systems. It emulates the standard PC Windows Explorer file management system in order to minimize special training requirements. Drag–and–drop techniques are employed for database–mapping. NTX Explorer is used for configuration of the unit; in the field or the convenience of your office. Using Ethernet links to the NTX controllers provides an easy way to remotely download or upload a configuration to or from the controller via the WAN. Available configuration parameters include baud rate, Virtual RTU addresses, modem type, local I/O configurations, etc. All configuration changes can be made independently, stored in a file on the PC, and downloaded to the NTX when it is convenient. The configuration currently stored in the NTX can also be uploaded to the PC.

NTX Logic

NTX Logic Programming Application

Read More

NTX Logic is a programming application that runs on the NTX Series substation controllers to provide powerful and sophisticated capability for running local control processes. It combines ladder logic capability with powerful function blocks to give you the simplicity of a PLC with the performance of a high-end process controller.

As older substations are modernized or new substations are built, more device integration capability and less local I/O will be required.
