Product Description
The RX ThyReX is an
extremely compact industrial
SSR that is fully pluggable to
make installation and servic-
ing easy. This zero switching
relay can be used for resis-
tive and inductive loads. The
position of the M4 mounting
holes makes this solution
interchangeable with stan-
dard hockey-puck relays.
The control plug can have
either screw or spring termi-
nals. The power connection
can be a screw type plug, a
spring type plug or an open
two-spade FASTON solution
that comes with safety cov-
ers (no plugs). Both screw
and spring type power plugs
have a specially designed
security leaver to
lock/unlock. To facilitate
assembly, the RX ThyReX
can be ordered with its own
thermal pad (optional).
