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.
The pin assignment matches the pin assignment of the IBH S5-Current Loop Converter. The pin assignment is compatible with the 20mA (TTY) serial connector of the programming devices (connector PG S5): PG 670, PG 675, PG 685, PG 635 and PG 750. 25pin Sub.D female connector with the pin assignment A...22, B...10, C...8, D...21, E/F...25.
