The IRZ-1 provides a convenient zonable (from 2 to 6 zones, both unidirectional and bi-directional depending on the "in the field" configuration) connecting point for remote relay systems, eliminating hard-wiring. The IRZ-1 will allow you to have multiple identical components being controlled independently of each other while attached to the same IR repeating system. Each room has it's own screw-down connector for the IRTarget and each emitter has their own 1/8" plug-in jacks. Routing control is provided by four simple to use jumpers. Gold plated header pins are used for maximum signal integrity. An auxiliary emitter expansion port (IRS-1) allows (4 max) more hard-wired emitter outputs than the standard 6 plug-in type.
