AutomationDirect Analog I/O expansion modules
The BRX PLC system offers analog I/O expansion modules in high-resolution current/voltage and temperature models. Two eight-channel analog current and voltage input modules and two eight-channel current and voltage output modules are available. Current signal ranges are 0-20 mA and 4-20 mA; voltage ranges are 0-5 Vdc, 0-10 Vdc, ±5 Vdc and ±10 Vdc. Input and output signal resolution is 16 bits (external 24 Vdc required). The four-channel temperature module supports types J, E, K, R, S, T, B, N and C thermocouples. The module also can be configured for four-channel millivolt level analog inputs.
