PKI-1R-5V – interface relay, normally closed contact, 5 V DC, 1/3S, TH-35

The PKI-1R-5V is an electromagnetic interface relay designed for use in low-voltage control circuits, automation systems and electrical installations requiring the isolation of control signals.

The relay is equipped with a normally closed (NC) contact and a coil powered by 5 V DC, enabling it to work with electronic circuits, PLCs, microprocessor-based systems and various types of control modules.

When supply voltage is applied to the relay coil, the NC contact opens, causing a change in the state of the controlled circuit. The relay’s active operating state is indicated by a built-in LED, which facilitates diagnostics and monitoring of the system’s operation. When the supply voltage is removed, the contact returns to its initial (closed) state.

Thanks to its narrow 6.2 mm (1/3 module) housing, the relay allows for optimal use of space in switchboards and control cabinets. The device is designed for direct mounting on a standard TH-35 DIN rail, ensuring quick and convenient installation in industrial and building systems.

The PKI-1R-5V interface relay is used wherever safe circuit control and signal isolation between control systems and actuators are required.

Applications:

• industrial automation

• PLC control systems

• electrical installations in switchgear

• building automation systems

• separation of control signals
