The DAM142 is for monitoring 24 digital input(can be used as pulse counter). It supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~30VDC.
The DAM142 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 DAM142 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module.
The DAM142 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
