DAM112 4DI+4DO Remote Data Acquisition Module
The DAM112 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 4 digital inputs (Dry Contact or Wet Contact, counter) and controlling 4 relay outputs.
Introduction
The DAM112 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 4 digital inputs (Dry Contact or Wet Contact, counter) and controlling 4 relay outputs.
The DAM112 Remote IO Module supports Modbus RTU Protocol over RS485 serial port. It 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; The digital output can control the intermediate relay or indicator output and supports pulse output.
Features
1. 4 digital inputs (Dry Contact or Wet Contact or Pulse counter), 4 digital relay outputs.
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 ensures its stability.
7. LEDs (Light Emitting Diode) for status indication make it easy to program in filed.
8. Small size, L70mm (about 2.76 in) *W88mm (about 3.46 in) *H30mm (about 1.18 in), support for wall mounting and DIN35mm (about 1.38 in) industrial rail mounting.
