Optimum Use of Plug-In Bridges
1
Description
The PLC INTERFACE module achieves maximum
efficiency with the user-friendly FBST plug-in bridge system.
The PLC-RS…/SEN makes effective use of the bridging
options for the power supply for sensors/switches, for the
supply/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 plug-in bridges that can easily be cut to
the required length and quickly inserted in the bridge shafts.
They eliminate the need for complicated and time-
consuming loop bridges – the reduction in wiring by
eliminating the need for modular terminal blocks and the use
of all bridging options is around 60%.
In applications as the interface between the PLC and
sensors (e.g., proximity switches, limit switches or auxiliary
contacts), as a rule only one N/O contact is required. In this
case, the PLC-RS…/SEN input module can be used, which
is specially optimized for these applications and consists of
a 6.2 mm basic terminal block and plug-in miniature relay
with screw or spring-cage connection.
1.1
No Need for Power Terminal Blocks
Unlike conventional input relays, all sensor connections,
including the supply voltage for the sensors and switches,
are connected directly to the PLC INTERFACE module. The
PLC-RS…/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 INTERFACE catalog).
