Endress+Hauser RIA452 LCD Process Indicator for Current, Pulse, Relay, Transmitter Power Supply, Voltage, 92mm x 92mm

The Endress+Hauser RIA452 can provide power directly to two-wire transmitters connected, intrinsically safe as an option. Up to eight freely programmable relays monitor the measured value for limit value overshoot and undershoot. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions (e.g. alternating pump control).
