Endress Hauser Process Transmitter RMA42 Integrated Loop Power Supply Two-wire Sensors
The Endress+Hauser RMA42 Process Transmitter and Control Unit processes analog measured values with indication, evaluation, and calculation capabilities. Its integrated loop power supply powers two-wire sensors, while universal inputs accommodate current, voltage, RTDs, and TCs. The unit features limit value monitoring, relay switching, and analog output for process signal forwarding. The included "differential pressure" application package enables quick commissioning for differential pressure applications.
