MR-AOP4 Modbus RTU, The Modbus module with 4 analog outputs was developed for decentralized switching tasks. It is suitable as a control variable transmitter for e.g. electric ventilation and mixing flaps, valve positions, etc. The outputs can be output via standard registers via a Modbus master. Each output can be set to automatic or manual operation via 4 potentiometers on the front. The module is addressed and the bit rate and parity are set using 2 address switches on the front or via software. Suitable for decentralized installation on TH35 mounting rails in accordance with IEC 60715 in electrical distribution boards. Connection with screw terminals
