Data acquisition unit, Data collection device, Modbus RTU RS485 4DI Instrument Parts & Accessories

Model:DAM124 

The DAM124 is for monitoring 4 digital inputs(can be used as pulse counter), 8 analog inputs, controlling 4 triode drivable digital output(50V/100mA, can be TTL or Pulse output). It supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~30VDC.

The DAM124 is used widely in industrial automation control systems. E.g.: Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on.

The DAM124 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module.

The DAM124 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
