Distributed input/output modules serve to create distributed control systems for technological objects and expand PLC functionality by increasing the number of I/O signals.

1. 4-channel analog signal output module VSAO-4

4-channel analog signal output module VSAO-4 with 4 isolated analog outputs serves to form permanent signals of either direct current or direct voltage or both through each of the four independent outputs. Data exchange with Master PLC is executed through a serial communication channel based on CAN-interface (ISO 11898).
Compatible with Selectron AOC 701 by Selectron Systems AG.

2. 4-channel analog signal input module VSAI-4

4-channel analog signal input module VSAI-4 with 4 isolated analog inputs serves to receive signals of either direct current or direct voltage or both from sensors and transform them into numeric code through each of the four inputs. Data exchange with Master PLC is executed through a serial communication channel based on CAN-interface (ISO 11898).
Compatible with Selectron AIC 701 by Selectron Systems AG.

3. 8-channel discrete signal output module VSDO-8

8-channel discrete signal output module VSDO-8 serves to send discrete signals to the executing devices through each of the eight independently controlled outputs. Data exchange with Master PLC is executed through a serial communication channel based on CAN-interface (ISO 11898).
Compatible with Selectron DOC 701 by Selectron Systems AG.

4. 8-channel discrete signal input module VSDI-8

8-channel discrete signal input module VSDI-8 serves to receive discrete signals from sensors through each of the eight inputs. Data exchange with Master PLC is executed through a serial communication channel based on CAN-interface (ISO 11898).
Compatible with Selectron DIC 701 by Selectron Systems AG.
