– Integrated input circuit,

– Input or power optical coupler can be supplied,

– IP67-protected fully encapsulated optical electronics,

– Insensitive to vibration and shock,

– User-specific marking

– Inflammability class V0 in acc. with UL94.

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-

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

applications and consisting of a 6.2 mm base terminal

block and pluggable miniature optical coupler. 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 optical couplers, all the sensor

connections, including the voltage supply for sensors/

switches (!), are connected directly to the PLC sensor

interface. PLC-OSP...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-OSP...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. Especially effective here are the 500 mm

long color-insulated continuous bridges that can easily

be cut to the required length and inserted in the bridge

shafts in a flash. 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-OSP...SEN naturally offers the same benefits as

all other PLC series with optical coupler:

– Switching capacity of up to 24 V DC/2 A, depending

on the type,

– Wear-resistant switching,
