GPIO-1 wiring schematics

 

This article explains how the various GPIO-1 inputs and outputs can be wired.

GPIO-1 inputs

 

1. High Range Monitored Input – Active High - 24VDC Locally Sourced
Notes: Vocia software configured as High Range Monitored  - Active State High. Circuit shown in Low State.

Notes:
• Low Voltage = 0 – 0.8 VDC.  Logic High = 2 – 5VDC.
• If configured as Active State High Alarm/Fault/Reset triggers when voltage transitions from Low to High.
• If configured as Active State Low Alarm/Fault/Rest triggers when voltage transitions from High to Low.
