• Conductivity or Resistance
Inputs
• Output and Input LED
Indication
• 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.
