I/O Modules

Modbus RTU N

Modbus RTU N is a family of industrial I/O modules for an RS-485 Modbus RTU bus: 8 digital inputs and 8 outputs, 8 analog inputs or 8 analog outputs in the same housing for a 35 mm DIN rail. DC 7…36 V supply with isolated power and RS-485; the address and baud rate are set by a Modbus command. The modules bring status and alarm signals and readings of 4–20 mA and 0–10 V sensors into a SCADA system or BMS and control valves, dampers and variable-frequency drives.
