Name: Distributed Data Acquisition Modules 8AIN 4 Pt Resistance Thermometer model
Model:DAM134
The DAM134 is for monitoring 8 analog inputs, measuring 4-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 DAM134 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 DAM134 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module.
The DAM134 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.
Mainly Features:
- 24-bit resolution high precision AD acquisition and data processing techniques
- 8 analog input, can be 0~20mA,4~20mA,0~5V,0~10V;
- Wide range power supply with reverse polarity connection protection;
