Networking: 8-channel 16-bit Ethernet analog I/O modules

Two I/O modules provide an 8-channel interface for differential analog voltage or current input signals.

According Acromag, the sub-$300 price is the industry’s lowest for an 8-channel module with 16-bit A/D conversion to Ethernet.

Acromag has expanded its BusWorks Ethernet I/O series of modules for distributed I/O and SCADA with new 967EN and 968EN models providing an 8-channel interface for differential analog voltage or current input signals. Each model is available in industrial and commercial-grade versions starting at just $295. They are designed to reduce costs for applications that do not need wide operating temperature ratings, advanced signal processing, or hazardous location safety approvals. According to the company, the sub-$300 price is the industry’s lowest for an 8-channel module with 16-bit A/D conversion to Ethernet. Industrial-grade units add superior accuracy, a signal integrator/totalizer function, peer-to-peer messaging, -40 to 70 °C capability, and ability to meet UL/cUL Zone 2 Class 1 Division 2 ABCD requirements. All units provide 16-bit A/D conversion of sensor inputs for Modbus TCP/IP control network communication. Common applications include monitoring temperature, pressure, flow, and level instruments in process control, automation, remote data acquisition and supervisory management systems.
