Yokogawa PSCDM024DCBAN 16800‑5415 Safety Digital Output Module

The Yokogawa PSCDM024DCBAN 16800‑5415 is a safety‑certified digital output module for Yokogawa ProSafe‑PLC SIS safety instrumented systems. It receives safety logic commands from the SIS CPU and outputs 24VDC discrete control signals to drive field actuators, solenoid valves and safety‑related trip devices for interlock and emergency shutdown actions.

This plug‑in rack‑mount module supports hot‑swap operation and integrates comprehensive self‑diagnosis to detect output circuit faults. It fits standard ProSafe‑PLC rack slots and is widely installed in SIS safety cabinets within petrochemical, refinery and power‑generation process facilities.
