Honeywell MC-PAOY22 Analog Output Module | 80363969-150

Configured for current loop control execution and field final element actuation in Honeywell High-Performance Process Manager platforms, the Honeywell 80363969-150 (MC-PAOY22 Analog Output Module) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The MC-PAOY22 module provides 16 conformal-coated channels for precision current loop control. Operating in conjunction with 4-20 mA HART loop protocol field devices, internal digital-to-analog conversion circuits output continuous control signals to positioners and actuators. Channel-to-channel isolation limits ground loop currents and cross-talk, preserving signal integrity across parallel field circuits.

Frequently Asked Questions

Q: Does the conformal coating on the 80363969-150 module alter electrical installation requirements?

A: No. Conformal coating provides environmental protection against airborne contaminants but does not alter pinout, backplane connections, or field wiring procedures.

Q: Can the MC-PAOY22 module be replaced while the chassis backplane remains powered?

A: Module removal must follow standard Honeywell I/O maintenance procedures. Isolate external loop power and release module retaining hardware before extraction to prevent transient signal disruptions.

Q: How does channel-to-channel isolation impact current loop performance?

A: It isolates individual 4-20 mA output channels electrically, preventing potential differences between field grounding points from affecting neighboring loops.

Field Installation Guidelines

• Verify backplane keying alignment prior to seating the MC-PAOY22 card into the rack slot.
• Fully engage rear bus connectors and tighten top and bottom retaining screws to establish chassis ground continuity.
• Route 4-20 mA analog output conductors in shielded twisted-pair cabling separated from high-voltage AC lines.
• Ground all field cable shield drain wires at a single central system instrumentation earth grounding bar.
• Wear an ESD wrist strap connected to chassis ground during module handling to protect sensitive analog electronics.
