This module can be programmed to run independently from the PC and it receives control signals from digital field devices (sensors, switches and etc). External load can also be swtiched via its digital output from the control system.

Each input points incorporates a noise or debounce rejection filter. The filter time constant can be freely programmable. All input points contains an optocoupler which provides electrical isolation between the module and the field devices. All input points status are indicated by LEDs.

All the output points are electrically isolated through the use of optocouplers. Small inductive loads (relays) can be connected directly without external protection. All output points status are indicated by LEDs.
