For PLCs, that are not supplying the loop current (2 x 20mA), the Constant Current Adaptor is required to establish a connection. Two constant current (20mA) sources are located in the solid metal 15 pin Sub.D connector shell to supply the loop current.
The adapter is delivered with a AC / DC adaptor.
