Thermocouple Input Modules

The six-channel, inch-wide I/O modules operate independently of any bus coupler or I/O rack, and do not require any special system power supply. Set up is simplified thanks to embedded Web pages, allowing configuration using any standard Web browser. No other software is required. Priced at $500 for a four-input unit, or $650 for six inputs, the 956EN Input Modules are cost effective for applications that need to monitor a small quantity of thermocouples per site, the vendor says. Flexible power requirements support operation on 15-36VDC power supplies. Each unit accepts thermocouple/millivolt inputs with user-selectable ranges for Type J, K, T, R, S, E, B or N sensors and bipolar +/-100mV or +/-1VDC signals. The I/O modules provide an isolated Modbus/TCP 10Base-T/100Base-TX network interface. Each module supports up to 10 sockets allowing communication with multiple masters.
