MC-PSRX04 51198947-100K Honeywell Power System Housing

Configured for centralized power distribution in Honeywell Distributed Control System platforms, the Honeywell 51198947-100K (MC-PSRX04 Power System Housing) provides direct physical/electrical execution.

Hardware Specifications

Process Control & Channel Isolation

The MC-PSRX04 Power System Housing distributes regulated power lines across backplane buses to drive digital, analog, and smart transmitter interface cards. Fully compatible with 4-20 mA HART loop protocol architectures, the backplane integrates robust channel-to-channel isolation and galvanic protection circuit paths. The conformally coated assembly protects copper traces against industrial atmospheric contaminants, preventing ground loops and common-mode noise propagation between redundant I/O processor channels.

Frequently Asked Questions

Q: How many I/O processors can be installed within a single MC-PSRX04 housing assembly?

A: The housing supports up to 40 redundant or non-redundant I/O processors across its backplane slots.

Q: What input and output power specifications govern the MC-PSRX04 backplane distribution?

A: The housing accepts a nominal 115 VAC input and provides a total output power capacity of 0.565 kW with DC current rails rated at 20 A, 1 A, and 0.035 A.

Q: How does conformal coating protect the backplane circuit board in harsh plant environments?

A: Conformal coating applies a protective polymer layer over the printed circuit assembly, preventing moisture, chemical gases, and particulate matter from causing corrosion or parasitic electrical leakage.

Field Installation Guidelines

1. Disconnect all 115 VAC primary power sources before mounting or servicing the MC-PSRX04 chassis.
2. Confirm that the housing is bonded securely to the cabinet grounding bus using heavy-gauge earth grounding straps to suppress electrical noise.
3. Ensure adequate vertical airflow spacing above and below the chassis assembly to maintain thermal dissipation across full 0.565 kW load profiles.
4. Verify that all processor card edge connectors are aligned correctly before fully seating modules into backplane slots.
