IBH Softec 2020 IBH S5-Current loop converter

The SMD electronics are located in a solid metal 15 pin SubнD connector shell. The pin assignment fits the following SIMATIC PLCs: 90U, 95U, 100U, 101U, 115U, 135U, and 155U. The 9 pin SubнD connector is plugged into the serial port (COM1 н.. COM4) of the PC. The PLC must be active and needs to supply the the loop current (2 x 20mA). If the PLC is passive, the Current-Loop-Converter can be used for power supply. The cable length of the IBH S5-Current loop converter is 3 meters.
