The DAM400 is for measuring a 1-channel pulse current or alternating current frequency, supports Modbus RTU protocol over RS485 serial port, powered up by 8~30VDC, measurement frequency range is 0~50, 60, 100, 200, 500, 1k, 2k, 5k, 10k, 20k, 50k, 100kHz,voltage range is 20mV, 5V, 12V, 24V, 100V, 300V, 500V. Optional analog output range is 0~20mA, 4~20mA,0~5V,0~10V. The DAM400 is used widely in industrial automation control and measurement systems to measure frequency and transmit in ASCII data format to any RTU, SCADA, data monitoring, data loggers, PLC’s, process controllers and instrumentation that supports Modbus RTU Protocol over RS485 serial port. E.g.: Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on. The DAM400 is an industrial class, isolated designed, high reliability, low-power consumption, high stability and high precision data acquisition module. The DAM400 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
