861H
Hazardous Rated Solid State Relays
15 Amp Rating, SPST-NO, Internal Heat Sink
The Series 861H Hazardous Rated Solid State Relay provides reliable switching
and long life operation in some of the most demanding applications, such as medical
equipment, mining, oil and gas. It integrates an internal heat sink and internal snubber
into a compact housing to save space in the panel. In order to reduce installation time,
integral tabs can be used to snap the relay onto a DIN rail or surface mount to a wall inside
the panel. LED indicator lights give the user quick visual indication of the switch status.
The 861H is intrinsically safe rated for Class 1, Division 2 Groups A, B, C and D.
