SPST-NO, 8 A to 15 A
SPST-NC, 10 A
Description
The 861 is the first complete solid state relay without any moving parts, all in a slim
17½5 mm design½
Feature
Solid state circuitry
Optically coupled circuit
Benefit
Involves no moving parts which extends product life,
increases reliability, and enables silent operation
Provides isolation between input and output circuits
Helps protect the relay’s internal circuit from high
voltage transients
Provides factory-tested thermal management
Helps prevent an operator from touching live circuits
Mounts directly onto DIN rail or panel and provides flexibility
to accommodate last minute design changes
