Safety Shutdown Solution – Yokogawa PSCDM024DCBAN | ProSafe-RS CDM Critical Discrete Module
Where This Product Is Used
The Yokogawa PSCDM024DCBAN is a Critical Discrete Module (CDM) designed for the ProSafe-RS Safety Instrumented System (SIS). It is deployed in safety-critical environments where reliable digital I/O is essential for Emergency Shutdown (ESD), Fire & Gas (F&G), and Burner Management Systems (BMS). Typical installation sites include:
- Oil & gas upstream/downstream processing plants
- LNG terminals and petrochemical refineries
- Chemical and pharmaceutical batch processing facilities
- Power generation and utility control rooms
- Offshore platforms requiring IEC 61511 compliance
