INTERFACE
PLC-RS…/21
Data Sheet
1Description
PLC-RS…/21 relay modules, which can be used
universally, comprise 6.2 mm basic terminal blocks and
plug-in miniature relays with PDT contact and screw or
spring-cage connection.
1.1 PDT Offers a High Degree of Flexibility
The PLC-RS…/21 universal PDT module is used whenever
an application requires a high degree of flexibility. It can be
used either as an input or output module or in N/O, N/C or
PDT contact applications.
This offers the advantage of fewer ordering and
warehousing items. PLC INTERFACE modules are
supplied fully equipped with a relay as standard.
1.2 Input Voltages From 12 V to 230 V
PLC-RS…/21 is available on the coil side in all common
industrial voltages from 12 V to 230 V. A further advantage
is the ready-integrated input circuit. It consists of a status
indicator as well as free-wheeling diode and polarity
reversal protection function, and ensures that the operating
state is displayed clearly, also offering reliable EMI
suppression for the coils and preventing destruction should
the polarity be accidentally reversed.
1.3 Optimum Use of Plug-In Bridges
The PLC INTERFACE module achieves maximum
efficiency with the user-friendly FBST plug-in bridge system.
The PLC-RS…/21 makes effective use of the bridging
options for the A1/A2 connection on the coil side and for the
grouped power supply at connection 11 on the contact side.
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.
1.4 Additional Advantages
– Operational safety with RT III (IP67)-protected
mechanics
– Environmentally friendly, cadmium-free power contact
material for loads up to 250 V AC/6 A
– Available with gold coating for low power levels (mA) as
an option
– Integrated input circuit
– Relay can be replaced using an engagement lever
– Safe isolation according to DIN EN 50178
– Inflammability class V0 according to UL94
