Product Details
The Honeywell 51155506-101, also cataloged as the 51155506-101 Relay Cable Assembly, operates as a dedicated hardware component for digital output (DO) relay signal transmission within Honeywell Experion LX system platforms. It links control modules to relay termination assemblies using an 18 AWG stranded conductor harness rated for 300V AC/DC and 5A current load per channel across Form C (SPDT) contact loops.

Channel-to-Channel Isolation & Loop Protocol Integration
The 51155506-101 cable assembly utilizes heavy-duty insulation providing 1500V AC galvanic isolation between internal control circuits and external field contacts. This high isolation threshold prevents field-side inductive transients from penetrating backplane logic networks. The structured conductor orientation suppresses cross-channel coupling, preserving signal routing integrity when high-density digital output loops run parallel to sensitive 4-20 mA HART loop protocol field wiring within the cabinet enclosure.
Frequently Asked Questions
Q: What is the primary function of the 51155506-101 cable?
A: This cable assembly provides structured physical wiring connectivity for digital output relay modules within the Honeywell Experion LX system architecture.
Q: Can this cable assembly be installed in high-vibration control environments?
A: Yes, the assembly is rated for industrial vibration levels up to 2g at 10-150 Hz, making it suitable for standard control cabinet installations.
Field Installation Guidelines
- Disconnect all system and field-side power before connecting or disconnecting the cable assembly to protect sensitive DO module output drivers.
- Route the assembly through dedicated wire ducts separate from high-voltage AC power mains to avoid electromagnetic interference (EMI).
- Align header pins accurately before fully seating connectors, ensuring mechanical strain reliefs are engaged without forcing the connection.
- Maintain minimum cable bend radii during routing to prevent internal conductor fatigue or dielectric insulation failure.
