Coupling relay and solid-state-relay
Please select:
PLC Interface - the original
It connects your control with the periphery with special skill and has already proven this millions of times. Benefit from the excellent system compatibility. Profit from the complete perfected range. Use the original.

PR series - Relay module system with upscale basic functions
It consists of DIN rail bases, relays, pluggable input/interference suppression modules, engagement levers as well as marker labels and bridging material - Customized for your requirements.
Minimize your logistics and mounting work by ordering pre-mounted modules. The PR relay bases are available with screw or spring-cage connection methods both for
- miniature power relays (1 or 2 PDT contacts) as well as
- industrial relays (2 or 4 PDT contacts).
The relay modules are broadly compatible with the commercially available standards and have the most important international approvals.

DEK series - Relay modules in the modular terminal block design
In conjunction with standard terminal block accessories, these high capacity relay interfaces have not only the design but also the high level of user convenience of modular terminal blocks.

ST series - Pluggable coupling relays and solid-state relays
The ST concept:
The DIN rail-mountable, direction-coded basic terminal block bases act as a terminal strip and simultaneously form the basis for the active interface connectors ST-REL. . . in a coupling relay version as well as ST-OV... and ST-OE... in a solid-state relay version.
Pluggability provides maximum flexibility and ease of maintenance. When servicing the system, the modules concerned can simply be removed from the strip and replaced.

EMG series - Flexible and combinable
The circuit variants of the interfaces of the EMG series offer all the possibilities of process and control-related signal processing.
