Analog input module DAM140

Modbus RTURS485automation

Brief instruction Ø The DAM140 is for monitoring 16 analog inputs(0~20mA,4~20mA,0~5V,0~10V). It supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~30VDC. Ø The DAM140 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. Ø The DAM140 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module. Ø The DAM140 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields Mainly Features Ø 16-bit resolution high precision AD acquisition and data processing techniques; Ø 16 analog input, can be 0~20mA,4~20mA,0~5V,0~10V; Ø Wide range power supply with reverse polarity connection protection; Ø Modbus RTU Protocol; Ø ESD Protection circuit for RS485 serial port; Ø Using industrial-grade chips; Ø Built-in watchdog ensure it reliability; Ø Lightning protection ensure it stability; Ø LEDs for status indication makes it easy to program in filed.
