The PLC-R...21 relay series, that can be used

universally, consisting of 6.2 mm base terminal blocks

and pluggable miniature relays with PDT contact, has

now been included in the range with spring cage

connections. The wiring, diagonally from above, is

particularly convenient during assembly. The cost-

intensive wiring is reduced yet again when the plug-in

bridges are implemented. A side-effect is a cut in the

likelihood of faulty wiring and time-consuming trouble-

shooting.

PDT = great flexibility

The universal PDT series, PLC-RSP...21, is used

whenever an application demands great flexibility. It can

be used

– as an input or output interface or

– in N/C, N/O or PDT applications.

Advantage: fewer ordering and warehousing items. In

the standard version, the PLC interfaces are supplied

equipped complete with relay (or miniature optical

coupler with electronic N/O function).

Input voltages of 12V to 230V

PLC-RSP...21 on the coil side is, like the proven

screw clamp versions, available in all conventional

industrial voltages from 12 V to 230 V. A further

advantage is the ready-integrated input circuit. It

consists of a status display, damping function, and

polarity reversal protection function, and guarantees a

clear display of the operational status, EMC interference

suppression of the coil, and prevents destruction of the

same, should the polarity be accidentally reversed.

Robust miniature relay

The heart of the PDT relay series is a robust

miniature relay from the latest generation, equipped

with features that you will search for in vain in most

standard pluggable relays:

– Operational safety with IP67-protected mechanics,

– Environmentally friendly, cadmium-free power contact

material for loads up to 250 V AC/6 A,

– As an alternative with a gold layer for smaller

capacities (mA),

– Reliable isolation in acc. with DIN VDE 0106-101,

The relay is securely fastened using an engagement

lever. Should it become worn, it can be disengaged, and

– without disconnecting the wiring – replaced quickly

and economically.

Plug-in bridges save wiring

A big plus for cunning wiring professionals is the

convenient plug-in bridge system FBST. Whether there

is an A1/A2 ground on the coil side, or group feed-in at

contact 11 on the contact side, the continuous plug-in

bridges which can be cut to length as desired, or the 2-

economical and fault-free wiring, whilst providing

utmost clarity. This makes complicated, time-consuming

loop bridges a thing of the past!
