Introduction :
The DAM204 is convert 4-channel analog output signal 4^ 20mA, 0^ 20mA, 0^ 5V, or 0^ 10V from any RTU, SCADA, data monitoring, data loggers, PLC? s, process controllers, instrumentation that supports Modbus RTU Protocol over RS485 serial port. and transmit in ASCII data format to engineering units for control equipments. It is an industrial class, high reliability, low-power consumption, high stability and high precision control module. Powered up by 12VDC or 24VDC.
The DAM204 is used widely as an extension control module in of Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on.
The DAM204 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
