PLC-RSP-230UC/21-21AU/RWF
Data Sheet
Description
The PLC-RSP-230UC/21-21AU/RWF relay module is
designed for input voltages with a nominal frequency of
16 2/3 Hz and is therefore ideal for railway applications. It
consists of a 14 mm wide basic terminal block with spring-
cage connection and a plug-in multi-layer contact relay with
two PDT contacts for small switching loads.
Rugged Miniature Relay
The heart of the PDT relay series is a rugged miniature
relay from the latest generation, equipped with features that
are lacking in most standard plug-in relays:
– Operational safety with IP67-protected mechanics
– Environmentally friendly, cadmium-free power contact
material for loads up to 250 V AC/2 x 6 A
– Hard gold-plated contacts for small loads
–4 kV
rms
electrical isolation between coil and contact
Plug-In Bridges Save Wiring
The FBST plug-in bridge system offers a big advantage:
whether an A1 or A2 connection on the coil side or grouped
power supply at connections 11 and 21 on the contact side,
with just one "click" the continuous bridge, which can be cut
to length, or the 2-pos. bridge connector ensure quick cost-
effective, and error-free wiring, while providing maximum
clarity. This makes complicated, time-consuming loop
bridges a thing of the past.
Additional PLC Advantages
The module naturally features the usual advantages of the
PLC range:
– Integrated input circuit
– Relay can be quickly replaced using an engagement
lever
– Safe isolation between input and output
– Marking labels from the standard modular terminal
block range
– Inexpensive
