📦 Product Overview – Yokogawa SCP451-53
The Yokogawa SCP451-53 is a 4-channel analog output module designed for use within Safety Instrumented Systems (SIS), supporting SIL-3 functional safety requirements. It is part of the ProSafe-RS series and is engineered for industrial environments where reliability, precision, and fail-safe operation are mandatory.
This module converts digital commands into precise analog outputs (current or voltage), driving control valves, actuators, or signal transmission equipment in safety-critical applications. It ensures strong isolation, high signal fidelity, and robust resistance to vibration and environmental stress.
