Keterangan
Honeywell CC-SDOR01 51308380-175 DO Relay Extension Board
Configured for digital output relay expansion in DCS I/O architectures, the Honeywell CC-SDOR01 51308380-175 (51308380-175 DO relay extension board) provides direct physical/electrical execution for discrete output switching across distributed control backplane environments.
The module implements 32 independent relay output channels with jumper-selectable Form A (SPST/NO) or Form B (SPST/NC) contact configuration per channel. Electrical isolation is maintained at channel level with 1500 VAC RMS or ±1500 VDC channel-to-channel and channel-to-logic common separation. Output contact material is AgSnO2, supporting mixed resistive and inductive switching profiles within defined inrush constraints.
Suffix Breakdown & Model Matrix
No manufacturer-provided suffix decomposition is defined for CC-SDOR01 51308380-175. The spare model 51308380-175 represents the base ordering identifier without documented functional segmentation.

Channel Isolation & Relay Output Architecture (Honeywell Process I/O Domain)
The module implements galvanically isolated relay outputs per channel group, designed to prevent cross-channel coupling under mixed inductive load conditions. The 1500 VAC RMS isolation barrier is applied between logic domain and field switching elements, supporting fault containment at channel boundary level.
In relay switching operation, contact degradation is governed by AgSnO2 material behavior under repetitive inrush conditions up to 10 A peak surge events. External surge suppression (120 Ω + 0.033 uF per channel) is specified for coil transient damping, reducing contact arc energy during de-energization cycles.
Frequently Asked Questions (FAQ)
Q: Can each output channel be configured independently as NO or NC? A: Yes. Each channel supports jumper-based selection between Form A (SPST/NO) and Form B (SPST/NC) operation.
Q: What is the isolation boundary within the module? A: Channel-to-channel and channel-to-logic isolation is specified at 1500 VAC RMS or ±1500 VDC.
Q: Is the module suitable for high inrush inductive loads? A: The relay supports up to 10 A inrush for 4 s at 10% duty cycle, subject to external suppression implementation.
Field Installation Guidelines
Field wiring shall maintain segregation between low-voltage logic cabling and relay output conductors. Shield termination should be executed at cabinet ground reference only to avoid ground loop injection across isolated channels.
Relay output contacts should be routed with consideration for arc suppression components (120 Ω + 0.033 uF per channel) when driving inductive loads such as solenoids or contactor coils. Mechanical mounting must ensure stable DIN rail or chassis fixation to prevent vibration-induced terminal loosening in multi-channel switching environments.
Terminal torque values and conductor cross-section must comply with cabinet-level wiring standards for relay output assemblies, ensuring consistent contact resistance across all 32 channels.
