Securasound Ltd

The Bentley group of relays are capable of switching 250V AC at a current of 5 Amps

The range has three available options:-
• 12V version AT-234
• 24V version AT-235
• Toggle relay AT-233

Both 12 & 24 volt versions have parallel input terminals to allow for ease of daisy chaining units together. The 12 & 24 volt units are built on a common blank printed circuit board; they are clearly marked as 12 or 24V during manufacture. This makes manufacturing most cost effective and the units the ideal choice where cost is an important factor.

Toggle relay can be triggered by
a) Positive applied
b) Positive removed
c) Negative applied
