Distributed Data Acquisition Modules 8-Channel Pt Resistance Thermometer Module model

Model:DAM304

The DAM304 is for measuring 8-channel Pt resistance thermometer of PT100, PT500, PT1000, CU50,CU100 or other PT Resistance Thermometers 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. Powered up by 10~30VDC.

The DAM304 is used widely in industrial automation temperature measurement systems. E.g.: Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on.

The DAM304 is an industrial class, isolated designed, high reliability, low-power consumption, high stability and high precision data acquisition module.

The DAM304 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
