Yokogawa 16137‑119 Terminal Adapter Module

The Yokogawa 16137‑119 is a field terminal adapter module for ProSafe‑PLC SIS safety instrumented systems. It serves as intermediate signal interface between safety I/O modules and field wiring, providing reliable screw‑type terminal connections for process‑industry field sensors and actuators.

This plug‑in terminal unit adopts industrial‑grade wiring terminals and internal signal conditioning circuits. It supports convenient field wiring modification and troubleshooting, and can be replaced without modifying external field cables. It is widely deployed inside petrochemical, refinery and power‑plant SIS safety cabinets.
