Introduction

Description

The Extron IPA T RLY4 Relay Accessory is an IPLink® Accessory product. The Relay Accessory consists of four output relays with normally open (when the relay is de-energized) (NO) and normally closed (NC) contacts.

The Relay Accessory converts a solid state (up to 12 VDC) signal, from a source such as the Flex I/O port of an Extron IPL T SF24 or the digital I/O port of an MLC 104 IP Plus, to a relay contact closure. The relay contacts can handle up to 24 VAC or 24 VDC as a tally signal, contact closure signal, or control signal to drive devices in your system, such as a lighting system (figure 1) or remote screens. The relay contacts are protected by an overvoltage circuit.

1IPA T RLY4 • Introduction

Connections

NThe 5-pole captive screw input connector and four 3-pole captive screw output connectors are included with the unit, but you must supply the cable. Extron recommends its CTL Series cable, part #22-148-nn (non-plenum bulk rolls), 26-119-nn (plenum bulk rolls), or 26-461-nn (plenum pre-cut lengths).

Input connections

A	Inputs — Connect the 12 VDC source to the common voltage (C)
	terminal of the 5-pole captive screw connector. Connect the
	appropriate input terminal (1 through 4) to the digital output(s) of
	the IPL T SF24, MLC 104 IP Plus, or other device.

CConnect +12 VDC to the C pin only and connect the return to one or all of the Input pins (1 through 4) for the relays that you will use. Reversing the connections can damage the power supply.

NConnect the I/O control line to the Input 1 terminal for relay 1, Input 2 for relay 2, and so on.

B Outputs — For each relay:

For the normally open contacts, connect a device between the NO and C terminals of the 3-pole captive screw connectors.

For the normally closed contacts, connect a device between the NC and C terminals of the 3-pole captive screw connectors.

Typical Da-Lite or Draper Low Voltage Controller

NOTE For a typical Da-Lite or Draper screen controller, a momentary closure on relay 1 or 2 causes the screen to move up or down. A momentary closure on relay 3 causes the screen to stop in its current position. Use 1N4001 or equivalent diodes (not included) for reverse bias protection.

Recommended diode specifications: 100 mA maximum through diode

50 V maximum reverse bias

Operation

When an input signal is applied to one of the relays, the signal toggles the state of that IPA T RLY4’s output relay; the relay’s NO contacts close, routing the signal for the connected device, and its NC contacts open, interrupting the signal for the connected device. See the chart below for clarification.

I/O mode	I/O state	Relay state
		NO		NC
Output	On (closed)	Closed		Open
	Off (open)	Open		Closed
