1 IPATRLY4•Introduction
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.

The 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).

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.
C Connect +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.
N
Connect the I/O control line to the Input 1 terminal for
relay 1, Input 2 for relay 2, and so on.

For a typical Stewart screen controller,
a momentary closure on relay 1, 2, or 3
causes the screen to move up, down,

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.
