CIO21A and CID21A input/output cards
The CIO21A input/output card provides digital/analog inputs and outputs; the CID21A cards provide digital inputs and outputs.
NOTICE
Connection of inductive loads to digital outputs.
Destruction of digital outputs.
If inductive loads are connected to digital outputs, you must install an external protective element (freewheeling diode).
