Togi PCN-1H40 40-Pin Terminal Block IDC Connector PLC I/O Wiring Module

Togi PCN-1H40 40-Pin Terminal Block IDC Connector PLC I/O Wiring Module

The Togi PCN-1H40 is a 40-pin IDC terminal block module designed to break out a ribbon cable or IDC connector into individually accessible screw terminals. It provides a convenient, organized interface between a flat ribbon cable and field wiring — a standard approach in PLC and industrial automation wiring panels. The module is housed in a sturdy beige plastic body with four orange locking clips that secure it to a mating rack or DIN rail channel.

Applications

40-pin IDC terminal block modules like the PCN-1H40 are commonly used in PLC (Programmable Logic Controller) I/O wiring systems and industrial automation panels. They serve as a transition point between a flat ribbon cable coming from a PLC I/O card and individual field wiring connections — each pin fans out to its own screw terminal, making it straightforward to connect, trace, or replace individual wires without disturbing the rest of the wiring. This type of module is a standard fixture in factory automation cabinets, motion control panels, and machine tool wiring. The Togi brand is a Japanese manufacturer known for this class of industrial connector and terminal block hardware, placing this component within the broader Japanese industrial automation ecosystem common from the 1980s through the 2000s.
