Product Details
Configured for high-power load control and voltage distribution in Experion PKS DCS platforms, the Honeywell 51155506-105 (51155506-105 Power Supply Module) provides direct physical/electrical execution. It converts 120/240 V AC supply power to drive internal system logic and manages heavy field actuators, motors, solenoids, and contactors via integrated high-capacity relay output channels.

4-20 mA HART Loop Protocol & Galvanic Isolation Integrity
The 51155506-105 module incorporates 1500 V AC channel-to-channel galvanic isolation barriers between its switching relays and system control backplanes. This electrical decoupling prevents high-voltage inductive kickback and ground transients generated by switched solenoid coils from corrupting adjacent analog input and output circuits. As a result, sensitive field instrumentation operating on the 4-20 mA HART loop protocol maintains uncorrupted signal transmissions across shared cabinet backplane paths.
Frequently Asked Questions
Q: Can the 51155506-105 power supply module be replaced while field loops remain energized?
A: No, main line power inputs (120/240 V AC) and high-current relay field contact loops must be de-energized prior to removing or inserting the module to prevent arcing and connector degradation.
Q: What contact configurations are supported by the onboard relay outputs?
A: The module outputs utilize Single Pole Double Throw (SPDT) relays, permitting wiring configurations for both Normally Open (Form A) and Normally Closed (Form B) operations.
Field Installation Guidelines
- Isolate and lock out all 120/240 V AC main supply circuits and external relay contact power sources before mounting the module.
- Secure the module onto the enclosure mounting base using the integrated cabinet hardware to ensure complete chassis grounding contact.
- Plug the included 5-meter DO source relay cable assembly into the designated interface connector, taking care not to exceed the minimum bend radius during cable routing.
- Separate high-voltage AC power feed lines from low-voltage signal wiring ducts to minimize electromagnetic interference (EMI) inside the panel.
