This station provided economical analogue output expansion for PLC's plus was also designed for use as a Remote Station.

The 8 analogue outputs are factory configurable as 4~20mA, 0~20mA, 0~10Vdc, 2~10Vdc.

PLC Application:

The 2100-AO is driven by the PLC to determine the output channel and the output level. Here are 2 options for connecting between the PLC and 2100-AO.

Option 1: Using one analogue output from the PLC plus 4 on/off outputs.

Option 2: Using 7 on/off outputs from the PLC (no analogue output required).

For further details, please refer to the Installation Guide.
