• Independent Operation

 

• Pluggable Terminal Blocks

 

• Din or Surface Mount

 

• 24 to 240VAC Supply

Operation

Independent Channel Relay 

Supply voltage must be applied to the IS_-R relay during operation. The IS_-R can have 1, 2, 3 or 4 channels. When IS input #1 closes its LED changes and #1 output contact closes. When IS input #1 opens#1 output contact opens. Each channel operates independent of the other channels.

 

LED indicators are:

Red - When the IS input is open or high

Green - When both the IS input & output contact are closed

Flashes - During transition delay A green LED indicates when supply

     voltage has been applied to the IS_-R.
