Low-cost Analog Ethernet I/O

May 6, 2009

The vendor has expanded its BusWorks Ethernet I/O series of modules for distributed I/O and SCADA with 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 to reduce costs for applications that do not need wide operating temperature ratings, advanced signal processing, or hazardous location safety approvals. The sub-$300 price is the industry’s lowest for an 8-channel module with 16-bit A/D conversion to Ethernet, says the vendor. Industrial-grade units add superior accuracy, a signal integrator/totalizer function, peer-to-peer messaging, -40°C to 70°C capability, and are designed 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.Acromag Inc. www.acromag.com248.295.0880
