Operating Instructions

ACT 120L
Transistorised Relay

The ACT 120L is a 12VDC single pole latching transistorised relay,
providing voltage free changeover contacts. The relay has numerous
practical uses and can be triggered by a positive 5V+ or negative 0V
applied signal. If required, the relay will latch by connecting jumper link
across J1. Reset is achieved by momentarily removing J1 or interrupting
the 12VDC supply. The single pole relay changeover contacts are rated at
3Amp/24VDC max.
PCB holes are provided for self-adhesive mounting feet supplied.
