The Acromag NT2140 Discrete AC Input Module is a high-performance Ethernet AC input module. Designed to sense the on/off power status of pumps, motors, and other AC-powered equipment.
Ideal for industrial pump monitoring, motor control, and process automation, the NT2140 offers reliable AC voltage sensing. In addition, flexible Ethernet connectivity — all in a compact, DIN-rail-mountable package.
Key Features
Six AC Optocoupler Inputs – Accepts 120V or 240V AC for detecting the presence or absence of voltage.
Two DC Logic I/O Channels – Monitor or control TTL or 0–32V logic levels.
Multiple Industrial Protocols – Modbus TCP/IP, EtherNet/IP, and PROFINET for seamless PLC/PAC integration.
IIoT-Ready – Built-in OPC UA server, MQTT client, and RESTful API for Industrial Internet of Things applications.
Expandable I/O – Add up to three NTX expansion modules via the integrated DIN rail bus. To achieve up to 64 I/O channels on a single network IP address.
Logic Control – Conditional IF/THEN/ELSE programming for local automation without a separate controller.
Peer-to-Peer Communication – Acromag’s i2o® technology allows direct data transfer between modules without a host.
Why Choose the NT2140 Discrete AC Input Module?
The NT2140 is built for industrial reliability. By combining AC voltage sensing with Ethernet-based protocols, it gives operators a real-time view of equipment status. Therefore, helping prevent downtime, detect power faults, and streamline maintenance.
If you need a discrete AC input module for pump monitoring in a water treatment plant, the NT2140 is a great choice. It is useful for controlling motors in factories. It also helps monitor status in oil and gas operations. The NT2140 offers precision, durability, and flexibility.
Typical Applications
Pump Monitoring – Detect when pumps are running or stopped via AC voltage presence.
Motor Status Monitoring – Identify motor on/off states to schedule maintenance or trigger alerts.
Switch & Sensor Inputs – Integrate limit, proximity, float, and toggle switches.
AC Power Supply Monitoring – Verify the presence of AC power in critical circuits.
Industrial Automation – Combine with PLCs or SCADA for process control.
Part of the NT2000 Series – Scalable, Modular, and Flexible
The NT2140 belongs to Acromag’s BusWorks® NT2000 Series. A versatile Ethernet I/O platform offering 16 I/O configurations.
Analog Models – Up to 16 inputs or 8 outputs for current/voltage monitoring and control.
Discrete Models – Up to 16 tandem input/output channels or 6 relays for on/off and high/low logic sensing.
Temperature Models – Thermocouple and RTD inputs for multiple sensor types and ranges.
This modular approach lets you mix and match I/O types to suit your application. All using the same configuration tools and communication protocols.
