User’s Guide IPA T RLY4 Relay Accessory Box 68-739-03 Rev.
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.
Connections N 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).
