51308380-175 CC-SDOR01 Honeywell Digital Output Relay Extension Module

Honeywell 51308380-175 CC-SDOR01 Digital Output Relay Extension Module Made in Thailand

The Honeywell 51308380-175, also known by its functional module name CC-SDOR01, is a redundant digital output relay interface module designed for use in Honeywell Experion® PKS (Process Knowledge System) and Safety Manager control platforms. This high-integrity I/O module provides fail-safe, isolated relay outputs for driving critical field devices such as solenoid valves, motor starters, alarms, and emergency shutdown (ESD) actuators in demanding process industries—including oil & gas, refining, chemical plants, power generation, and pharmaceutical manufacturing.

Engineered for mission-critical applications, the CC-SDOR01 supports 1:1 hardware redundancy (dual-module hot standby) to ensure continuous operation even during component failure. Each module features eight Form C (changeover) electromechanical relays, offering normally open (NO), normally closed (NC), and common terminals per channel—enabling flexible control logic for both energize-to-trip and de-energize-to-trip safety strategies.

With robust diagnostics, galvanic isolation, and compliance with international functional safety standards (including IEC 61508 SIL 2/3 when used in certified architectures), the 51308380-175 delivers reliable, auditable, and maintainable digital output control in safety-instrumented systems (SIS) and basic process control systems (BPCS).
