Omron G7TC-OC16 DC24 16-Point I/O Relay Terminal Block

Model Identifier G7TC-OC16 DC24
Official Part Number G7TC-OC16 DC24
GTIN Standard NA

Technical Overview

The Omron G7TC-OC16 DC24 is a compact, highly efficient I/O relay terminal block designed to streamline programmable logic controller (PLC) field wiring. By utilizing a single multi-pole connector cable to link directly to the PLC, it drastically reduces panel space usage and minimizes point-to-point wiring labor. This unit features 16 independent NPN (+ common) output points equipped with Gold-clad Silver (AgInSn) crossbar contacts, capable of safely switching up to 5A at 24 VDC or 2A at 220 VAC. Engineered for robust industrial control, the G7TC series includes built-in coil surge suppression, intuitive LED operation indicators for immediate I/O status recognition, and standard DIN track mounting for rapid installation.
