The DAM102 remote data acquisition module is designed for harsh industrial applications and is used in a wide range of industrial automation measurement and control systems,for monitoring 2 digital inputs(Dry Contact or Wet Contact, counter). It supports Modbus RTU Protocol over RS485 serial port.
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 DAM series modules can be used in a variety of industrial automation measurement and control systems as a front-end for data acquisition control, directly connected to various actuators or transmitters, sensors, and detectors.
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.
1. 2 digital inputs(Dry Contact or Wet Contact or Pulse counter);
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;
