In interface applications between the PLC and

sensors, such as proximity switches, limit switches, or

auxiliary contacts, often only an N/O function is

required. Here, people turn directly to the PLC-

RSP...SEN input interface, specially optimized for these

applications and consisting of a 6.2 mm base terminal

block and pluggable miniature relay. In addition to the

proven screw clamp connection version, the sensor

interface is now available with spring cage

connections. The wiring , diagonally from above, is

particularly convenient during assembly.

No need for input terminal blocks

Unlike previous input relays, all the sensor

connections, including the voltage supply for the

sensors/switches (!), are connected directly to the PLC

sensor interface. PLC-RSP...SEN can thus be used

directly as a terminal strip with integrated interface

function for the incoming sensor cables, without the

need for additional modular terminal blocks. (See also

structural diagram in catalog part 6, page 30.)

Assessment of savings:

– Elimination of the costs of two (three) modular

terminal blocks for sensor/switch supply, signal and

sensor ground (in the case of three-conductor

initiators).

– Space savings of approx. 80 %,

– Time saving approx. 60 %,

– Reduction in wiring thanks to plug-in bridges.

Optimum use of plug-in bridges.

The sensor interface attains the maximum degree of

efficiency with the convenient FBST plug-in bridge

system. PLC-RSP...SEN makes effective use of the

bridging facilities for the sensor/switch voltage supply,

for the supply and sensor ground at the A2 connection,

and for the common supply potential of the PLC at

connection 13. No stripping, no pressing on of ferrules,

no connecting. This makes complicated, time-

consuming loop bridges a thing of the past!

Assessment of savings:

– Reduction in wiring by eliminating the need for

modular terminal blocks and using all bridging

facilities: approx. 60 %.

Further advantages:

PLC-RSP...ACT naturally offers the same benefits as

all other PLC series with relay:

– Switching capacity up to 250 V AC/6 A,

– Integrated input circuit,

– Available either as gold or power contact relay,

– The relay can be removed for replacement using the

engagement lever,

– Operational safety with IP67-protected relays,
