AC Relay Wildcard Users Guide

Introduction

This document describes how to use the AC Solid State Relay WildCard™. It provides an overview of the hardware and software for the module as well as a schematic.

The AC Solid State Relay Wildcard allows you to control up to four, 5 amp AC loads. You can stack up to eight AC Relay Wildcards on to a Mosaic embedded controller or you can mix and match any of the growing family of Wildcards. The following sections guide you through the AC Relay Wildcard’s hardware and software.

Hardware

Overview

The AC Relay Wildcard was designed to allow easy control of AC loads. Each AC Relay provides:

• Control of 12 to 280 VAC loads operating at 47 to 63 Hz and up to 5 Amps.
• Optically isolated control to 4000 Vrms.
• Zero voltage switching.
• Max turn on/off time of ½ AC Cycle.

The next sections show you how to connect the AC Relay Wildcard to the Wildcard Bus on a Mosaic controller and how to configure the module for proper operation.

Connecting To The Wildcard Bus of a Mosaic Controller

To connect the AC Relay Wildcard to the Wildcard Bus of a Mosaic controller, follow these simple steps:

With the power off, connect the Wildcard Bus on the AC Relay Wildcard to Wildcard Port 0 or Wildcard Port 1 on your controller or the Wildcard Carrier Board (These may also be called Module Port 0 or 1). If you are using a Wildcard Carrier Board, connect it to the QED Board as outlined in the "Wildcard Carrier Board Users Guide". The corner mounting holes on the Wildcard should line up with the standoffs on your controller.
The Wildcard Bus on the AC Relay Wildcard is located opposite from the screw terminals. CAUTION: The Wildcard Bus does not have keyed connectors. Be sure to insert the AC Relay Wildcard so that all pins are connected. The Mosaic controllers and the AC Relay Wildcard can be permanently damaged if the connection is done incorrectly.

Selecting the Wildcard Address

Once you have connected the AC Relay Wildcard to the Mosaic controller, you must set the address of the module using jumper shunts across J1 and J2.

The Wildcard Select Jumpers, labeled J1 and J2, select a 2-bit code that sets a unique address on the wildcard port of the Mosaic Controller. Each wildcard port on the Mosaic Controller accommodates up to 4 wildcards. Wildcard Port 0 on the Mosaic Controller provides access to wildcards 0-3 while Wildcard Port 1 provides access to wildcards 4-7. Two wildcards on the same port cannot have the same address (jumper settings). Table 1 shows the possible jumper settings and the corresponding addresses.

Once you have connected and configured all of the hardware properly, you can use the software drivers to control AC loads.
