Product Description
ILC LightMaster Input/Output Card
Also referred to as an I/O Card, Input/Outboard Board or I/O Board.
I/O Card: Provides connections between the Control Module and switch inputs, and relay outputs. 8 inputs, 8 outputs per board.
I/O Board(s) – Each I/O board provides eight (8) switch inputs and relay outputs, status pilots and override switches.
Major components include:
• Switch Inputs – can accept input from either 2- or 3-wire momentary or maintained dry contact devices. Each input has two associated LEDs (light emitting diodes). The ON LED lights when a closure is sensed between the ON and COMMON terminals. The OFF LED lights when a closure is sensed between the OFF and COMMON terminals. Each switch input features a switch pilot LED, which can be programmed to track the state of a single relay, relay group or preset. The inputs are optically isolated, noise- and surge-resistant. A switch and pilot may be located up to 1500
feet from the controller, provided you use a minimum of 18 gauge wire. As an alternative to hardwired switching, relays may be controlled by signals transmitted via a LightSync network. (See Section 4 of User Manual for details.)
• Relay Outputs – Each optically isolated output switches its associated lighting relay ON and OFF. Each output has an associated LED. The LED lights when the output switches the relay ON.
• Relays – 20A at 120, 277 or 347 VAC magnetically latching relays maintain their state even with a power outage.
• Override Switches – Each relay output is equipped with an ON and an OFF override switch. These switches allow you to turn the associated lighting relay ON or OFF independent of any programming.
