| Name: 8-Channel Thermocouple Module Model:DAM308 The DAM308 is for measuring 8-channel thermocouple of S, R, B, K, N, E, J, T or other thermocouples 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 DAM308 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 DAM308 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module. The DAM308 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
