Acromag’s new Discrete AC Input Modules Expand Ethernet Remote I/O Series with the Ability to Sense Power Status of Pumps and Motors

New I/O modules sense on/off AC voltage levels and contact closures to monitor remote equipment activity and detect power faults.

New Discrete AC Input Modules Expand Ethernet Remote I/O Series with the Ability to Sense Power Status of Pumps and Motors

Wixom, MI: Acromag added a new discrete AC input module, the Model NT2140, to their BusWorks® NT Ethernet I/O family. This new discrete I/O module provides six 120V or 240V AC optocoupler inputs for sensing the presence or absence of voltage plus two DC logic I/O channels to monitor/control TTL or 0-32V logic levels. Applications include monitoring on/off levels of pumps, motors, switches (e.g. proximity, limit, float, toggle), push buttons, thermostats, contact closures, and AC voltage power supply levels on a wide variety of equipment. A network interface supports Modbus TCP/IP, EtherNet/IP, or PROFINET protocols to communicate with programmable controllers (PLCs/PACs) or other networked devices. An OPC UA server, MQTT client, and RESTful API support Industrial Internet of Things (IIoT) applications.

NTE Ethernet models provide dual RJ45 ports for network communication plus the discrete I/O channels. NTX expansion modules add extra I/O channels to monitor more devices. Up to three NTX modules can link to the NTE communication module through an integrated DIN rail bus interfacing up to 64 I/O over a single network IP address. Other NT Series analog and discrete I/O modules offering a variety of signal processing functions can also be combined to monitor or control voltage, current, and temperature signals. Remote I/O modules are commonly used in chemical processing, oil/gas production, water/power utility, and manufacturing operations. 

“With these discrete AC input modules, you can confidently monitor the on/off power status of remote pumps, motors, and other switched devices,” states Robert Greenfield, Acromag’s Director of Business Development. “The NT2140 will sense the presence or absence of AC voltage levels for communication to your control system using a wide variety of industrial Ethernet protocols.”

The BusWorks NT2000 Series offers a broad variety of I/O signal processing options. Sixteen I/O configurations are available as either NTE Ethernet I/O or NTX expansion I/O models. Analog I/O models feature up to sixteen inputs or eight outputs for monitoring and controlling current or voltage signals. Discrete I/O models provide sixteen tandem input/output channels or six mechanical relays to sense or switch on/off and high/low logic levels. For temperature measurement, thermocouple and RTD input models support many sensor types and ranges.

Each module supports three industrial protocols (Modbus/TCP, EtherNet/IP, PROFINET) which are selectable using any web browser to configure the network settings and I/O operation. OPC UA, MQTT, and RESTful API support facilitate IIoT applications. The modules typically function as a network server, but also offer Acromag’s i2o® peer-to-peer communication technology to transfer data between modules directly or multicast without a host or master in between. Conditional logic capabilities let users control operations with IF/THEN/ELSE statements.
