provided for controlling low voltage contact closure devices such as drapes,
screens and lifts. Each connector is rated 2 A @ 50 VDC, MOV arc suppression.
The remaining five pins of this connector provide four software programmable
digital inputs plus ground. The inputs are Schmidt trigger type (nominal 2.5 V
threshold) with 24 V input tolerance. Digital inputs are rated 0 – 24 VDC,
2K ohms input impedance. Input logic threshold is 2.5 VDC nominal.
IR
The 3.5 mm TRS mini phone jack is used for controlling display devices via IR.
Connects to a STIRP IR emitter probe (sold separately).
Infrared output is rated up to 1.2 MHz.
