MR-AIO4/2-IP65 Modbus RTU

The Modbus module in an IP65 housing with 4 individually configurable resistance or voltage inputs and 2 analog outputs was developed for decentralized tasks. The inputs are suitable for detecting resistances and voltages of for example, passive and active temperature sensors, electrical vent and mixing valves, valve positions, etc. The outputs are suitable as encoder for control variables for example for electrical vent and mixing valves, valve positions, etc. Via a Modbus master the inputs can be configured universally by standard registers and the outputs can be set. The module address, the bit rate and the parity are set with two rotary switches or by software. The Modbus module has two integrated PID controllers which can be used for room control, for example. The settings of the PID controllers are done via the Modbus registers and can be found in the Modbus software manual at www.metz-connect.com. Using the Modbus Gateway MR-GW from METZ CONNECT, the settings can be done faster and more conveniently via the graphical interface of the built-in WEB server.
