Programmable Controllers

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. Fig. 1. Internal 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.
