Rascal Opto Isolators

A superb range of relay modules for the professional engineer. The Handy Rascal Relays boast “opto isolation” of input to output for added safety and to ensure circuits are truly electrically isolated.

There are 1, 2, 4, 8 and 16 way models and typical uses are for linking and controlling independent systems together such as CCTV, burglar or fire alarms, access control, gate automation, lighting and HVAC but they can be used in multiple ways by the professional installer.

Rascal Multifunction Timer

This versatile relay module has two independent timers built in to it so it can be set up to switch the relay contacts on and off in a variety of ways. With each timer being adjustable from 0.005s up to 270hrs (over 10 days!) it's a really versatile little rascal!! It has a total of 10 functions which include the useful delay on and delay off functions, perfect for sounders, gates, doors and lights.

Rascal DC-DC Booster

The Mini HRM402 Voltage Booster measures just 64mm x 35mm so it's tiny enough to fit in other equipment and actually contains a built in LED voltmeter. The output voltage can be turned up to 30V DC by simply turning a small adjuster on the PCB and by pressing a switch on the PCB you can oscillate between the input and output voltage so it’s very engineer friendly!
