Noby-21 Relay-1 (Click to enlarge)

Overview

    Features

  • 10 - 30V supply operating range
  • single DPDT DC relay
  • contacts rated up to 2 Amp at 28 Volt DC
  • transistor driven
  • operating status LED
  • coil suppressor diode

The Noby-21 Relay Module is designed for use in both 12v and 24v alarm systems. The DPDT voltage-free contacts permit switching of two independent circuits. Bridging the two contact sets together creates an effective single contact with a switching capacity of up to 4 amps. An on-board LED displays the activation state of the relay. Two adhesive mounting pillars are supplied with the Noby-21.

Typical applications include:

  • switching high currents directly from the battery (via an in-line fuse).
  • signal isolation between various parts of a system operating at different voltage supplies.
