Description

The YOKOGAWA PSCDM024DCBAN-16800-5415 is a 24-channel safe discrete input module designed for integration within Yokogawa’s ProSafe-RS safety instrumented system (SIS), a certified platform compliant with IEC 61508 and IEC 61511 for functional safety up to SIL 3. This module is engineered to reliably interface with field safety devices such as emergency stop buttons, limit switches, level sensors, flame detectors, and other dry-contact or voltage-sourced digital inputs in high-integrity protection systems. The PSCDM024DCBAN-16800-5415 plays a critical role in emergency shutdown (ESD), fire and gas (F&G), and process safety interlock applications by providing high-speed, fault-tolerant signal acquisition with comprehensive diagnostics.

As part of Yokogawa’s OpreX Safety portfolio, the YOKOGAWA PSCDM024DCBAN-16800-5415 supports redundant system architectures and hot-swap capability, ensuring maximum availability and operational continuity in mission-critical environments. It features advanced self-diagnostics, channel-to-channel isolation, and noise immunity to prevent spurious trips and ensure dependable signal integrity in electrically noisy industrial settings. The module seamlessly integrates with ProSafe-RS safety controllers (e.g., PSCCM22AAN-16418-5314) and other I/O modules, forming a complete, unified safety solution that can be engineered, monitored, and maintained using Yokogawa’s ProSafe-RS Engineering Station and FieldMate tools.

Main Features and Advantages

The YOKOGAWA PSCDM024DCBAN-16800-5415 delivers exceptional reliability and performance in safety-critical discrete monitoring applications. Its 24-channel capacity reduces system footprint and wiring complexity, making it ideal for large-scale ESD and F&G systems where numerous safety inputs must be monitored. Each channel is individually isolated and continuously monitored for faults such as open wires, short circuits, and internal logic errors, ensuring high diagnostic coverage required for SIL 3 compliance.

One of the key advantages of the PSCDM024DCBAN-16800-5415 is its integrated 24 VDC excitation, eliminating the need for external power supplies to energize dry-contact field devices. This simplifies wiring and reduces installation cost and potential points of failure. The module supports fast response times (<30>

Designed for seamless integration within Yokogawa’s ProSafe-RS platform, the YOKOGAWA PSCDM024DCBAN-16800-5415 works in conjunction with safety controllers and output modules to execute safety logic with deterministic timing. Its hot-swappable design allows maintenance and replacement without shutting down the safety system, a crucial benefit in continuous-process industries like oil & gas, petrochemicals, and LNG.

The module also supports secure communication and configuration via Vnet/IP, aligning with IEC 62443 cybersecurity standards. With long-term availability and global technical support, the PSCDM024DCBAN-16800-5415 is a future-ready component of modern, integrated control and safety systems (ICSS).
