DAM100 Dual Analog Input Modbus Module

DAM100 Dual Analog Input Modbus Module

The DAM100 is for monitoring 2 analog inputs 4 to 20 mA. It supports Modbus RTU Protocol over RS-485 serial port. Powered up by 10 to 30 VDC.

The DAM100 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 DAM100 is an industrial class, isolated design, high reliability, low-power consumption, high stability and high precision data acquisition module.

The DAM100 with fire retardant shell, standard 35 mm DIN rail makes it easy to install in fields.
