The
KMC REE-2101/2102 Solid State Relays provide zero-crossing triac switching for
use in building automation systems or any system where transients may pose a
problem. The REE-2101 relay provides four separate outputs while the REE-2102
provides a single output. A status LED is associated with the output of each
relay to indicate when the output is switched on. An Auto-Manual-Off jumper is
provided so the output may be overridden.
