Arrowhead Alarm Products EC-RELAY Multipurpose Relay Board Operating instructions

  • Hello! I've reviewed the instructions for the AAP EC-RELAY. This document details the operation of a multipurpose relay board with selectable 12V/24V operation and trigger options. It includes information on coil voltages, trigger modes, and contact specifications. I can help you with any questions you have about this device and how to operate it.
  • What are the available coil voltage modes?
    What is the current draw for the relay in 12V mode?
    What is the current draw for the relay in 24V mode?
    What are the available trigger modes?
    What is the maximum current allowed via contacts?
