Data Sheet 101780_en_02

## **1 Description** 

**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 colorinsulated 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 timeconsuming 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

- 1 The PLC-ATP BK insulating plate must be installed for voltages greater than 250 V (L1, L2, L3) between the same terminal points on adjacent modules (see "Accessories"). FBST 8-PLC... or FBST 500... is then used for potential bridging. 

With the 120 V and 230 V modules, an REL-MR-60DC/... 60 V relay is normally used due to the input circuit integrated in the basic terminal block. For the protection of input and output, inductive loads must be dampened with an effective protective circuit.
