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.
