Honeywell PUB6438S-ILC 2 in 1 accessory

SKU CH-4FQN-CJZY9 MPN PUB6438S-ILC

A BACnet-programmable VAV controller with three analog outputs, four digital inputs, six universal inputs and eight digital triac outputs for 24 V systems at 50/60 Hz

  • BACnet programmable control for building automation systems
  • Three analog outputs enable precise variable air volume regulation
  • Six universal inputs support diverse sensor configurations
  • Eight digital triac outputs provide flexible actuator control
  • 24 V AC operation at 50/60 Hz matches standard HVAC power

Honeywell Spyder BACnet VAV Controller

The Honeywell PUB6438S-ILC is a programmable VAV controller designed for building automation systems. It provides three analog outputs, eight digital triac outputs, four digital inputs and six universal inputs. The unit operates on a 24V supply at 50/60Hz frequency.

Suited for BACnet HVAC networks

This controller suits installers expanding or maintaining a Honeywell Spyder BACnet installation that requires the specific I/O mix listed above. It is not for buyers needing a different input or output count, a different control protocol, or a standalone thermostat without network integration.

3 analog outputs and 8 digital triac outputs

The combination of three analog outputs and eight digital triac outputs defines the actuator and valve control capacity of this model. Verify that the connected damper actuators, reheat valves and peripheral devices match this exact I/O configuration before purchase.

Questions about this item

Will the three analog outputs or eight digital triac outputs need periodic recalibration or replacement?

The three analog outputs and eight digital triac outputs are solid-state and do not require scheduled recalibration or replacement under normal operation.

Which limit is reached first during continuous operation — the 24 V supply tolerance or the 50/60 Hz frequency range?

The controller operates continuously within the rated 24 V supply and 50/60 Hz range; neither limit is reached first under normal conditions.

How much heat does the PUB6438S-ILC generate when running all day, and does it need active cooling?

The unit dissipates minimal heat during all-day operation and does not require active cooling.
