Honeywell PUL6438SR Spyder Relay Programmable Controllers Instruction
Manual
PRODUCT DESCRIPTION
The Spyder with relay controllers are part of the Spyder family.
These controllers are designed to control HVAC equipment.
These controllers provide many options and advanced system features that allow
state-of-the-art commercial building control. Each controller is programmable
and configurable through software. These controllers are for use in unitary
and advanced HVAC applications. Each controller has flexible, universal inputs
for external sensors, digital inputs, analog and digital relay outputs. The
Spyder with relay controllers are identical to the existing full sized Spyder
controllers with the exception of having 8 24VAC relay outputs as opposed to
24VAC triac outputs. The relay outputs are rated for 200,000 cycles, 1 Amp
continuous current and 3.5 Amps inrush for 100 milliseconds (1/10th of a
second).

WIRING
The digital outputs of the Spyder with relay are designed differently and therefore are wired differently than the other Spyder products. The relay outputs are internally designed to provide up to 3 isolated “banks” of contacts. The factory installs removable jumpers between 24VAC and common of relay banks A (three outputs) and B (four outputs). The last relay remains isolated but could be jumped in the field if desired. The diagram below represents the internal schematic of the digital output circuitry

In addition to this label, the factory includes another label for the DO’s that matches the typical terminal designations for a standard rooftop unit (e.g. instead of DO-XX the label has RH, RC, W, Y, G and AUX). If desired, this can be placed over the top of the existing label for more intuitive wiring.
