NL-AUX-RLY

NL-AUX-RLY NL900 accessory for Radio Modem
  • Overview
  • Specifications
  • Support

There are many applications where you need the quick availability of a relay for connection to a particular apparatus. The NL-AUX-RLY auxiliary dual relay box was designed to facilitate this need. The NL-AUX-RLY consists of two single-pole, double-through relays with a contact current rating of 6 amps at 250 VAC. A high voltage, high current relay driver IC is used to trigger the relays, thus allowing for a selectable active high or active low independent trigger source for each of the two relays

The NL-AUX-RLY works in conjunction with the NL900 and NL900S, when configured for dry contact closure function. A typical application is in remote powering of motors, pumps or any application requiring a simple isolated on/off switch.

High/Low Input Selection

Inputs 1 and 2 are selectable active high or active low by jumpers J3 and J4 respectfully. Both jumpers are located inside the case on the printed circuit board. The default setting is active high.
