2DI+2DO Remote Data Acquisition Module(2 digital input,2 relay output)
The DAM series remote data acquisition module can also be used as an expansion module of GSM 3G 4G RTUS27x, which can greatly expand the number of I/O ports of S27x to meet the needs of different applications.
The status signal of the switch can be returned to the host through the digital input, and the digital input has a counting function, which can be used as a pulse counter input.The digital output can control the intermediate relay or indicator output, and the digital output supports pulse output.
2. Modbus RTU Protocol over RS485;
3. Wide range power supply 9~36VDC with reverse polarity connection protection;
4. ESD Protection circuit for RS485 serial port;
5. Built-in watchdog ensure it reliability;
6. Lightning protection ensure it stability;
7. LEDs for status indication makes it easy to program in filed;
8. Small size, L110*W84*H30mm, support for wall mounting and DIN35mm industrial rail mounting.
