Effective alternative to end-to-end cabling

Effective alternative to end-to-end cabling

The requirements and complexity of the cabling between controller and sensors and actuators in machines and plants are constantly increasing. Our PLC interface units not only ensure seamless connections within the systems. Thanks to simplified cabling, they minimize sources of error and significantly reduce material and processing costs. In this way, they actively contribute to cost reduction and reliably guarantee the safe operating of systems.

PLC interface module types and solutions

Universal PLC system

Compatible to all known PLC manufacturers

Due to the need to reduce costs and save space and time in the construction of electrical cabinets, the universal wiring system for the PLC provides an efficient alternative to point-to-point wiring. Weidmüller offers a wide range of pre-made cables and interfaces for the main PLC manufacturers:

  • ABB
  • Emerson
  • Ge Fanuc
  • Honeywell
  • Mitsubishi
  • Omron
  • Rockwell
  • Schneider
  • Siemens
  • Yokogawa

Passive modules

Compact interface modules for various applications

The passive input/output interfaces for digital and analogue signals are available with screw or tension clamp connection technology. Sensors and actuators can be connected with 1, 2, or 3 wires and different functions like LEDs, fuses, disconnectors and test leads can be integrated.

Passive modules
Product features
  • Transmission of field signals to different types of plug-in connectors (SUB-D, Flat-cable, ELCO, RJ45, USB)
  • PCB terminals with tension clamp or screw connections for the field connection
  • Interfaces with diodes as overvoltage protection, lamp test or reverse polarity protection
  • Designed for fixing to TS 32 and TS 35 mounting rails

Relay insulated interface modules

Compact connection of relay modules to PLC systems

The compact modules provide interfaces to 4, 8 or 16 electromechanical and/or semiconductor relays. For quick wiring, the DC variants come with a shared positive or negative potential. The voltage of the controller can be adjusted to that of the field elements (e.g. sensors) by means of galvanic isolation with electromechanical or semiconductor relays.

Relay insulated interface modules
Product features
  • Groups of 4, 8 or 16 RCL (12.7 mm) or RSS (6.1 mm) relays
  • Possibility of insulating digital signals in both input and output cards
  • Clear marking: A green LED per channel ensures that each contact is clearly identified
  • Voltages from 5 to 230 V

Pre-assembled cables

Pre-assembled cables

Pre-assembled cables

Pre-assembled PAC cables, consisting of manufacturer-specific plug-in connectors as well as flat cable, SUB-D or RSV connectors, provide a fast and reliable connection between PLC and PLC interface modules.

Backplane systems

Fast integration of electrical equipment and components

Backplane systems allow various electrical components, such as SIL relays or analogue converters, to be connected quickly and conveniently. The reinforced circuit boards make it easier to add individual extra functions in a confined space. This accelerates the installation and vastly simplifies the connection to the PLC or DCS.

 Backplane systems
Product advantages
  • Universally applicable system for all common PLC types
  • Additional functions such as power supply alarms can be integrated without extra space
  • Easy installation and replacement of modules and components thanks to clip-fit fixing to the DIN rail
  • Pre-assembled cables in different lengths ensure error-free connections
