Safety Relays (Leuze)
With a width of just 17.5 mm and 22.5 mm, these safety relays are characterized by very narrow housings. As a result, you can realize the one- or two-channel connection of safety-related sensors in a space-saving and simple manner over up to three switch-off circuits. The devices have interchangeable connection terminals.

MSI-SR4
Short reaction time
The MSI-SR4 is used for evaluating safety-sensor input signals. Light curtains, E-Stop buttons and safety switches, for example, can thereby be integrated in the machine process in a safety-oriented manner.
- Standard link between machine control and Optoelectronic Protective Devices as well as safety switches
- Flexibly covers a wide range of applications
- Monitored start/restart button
- Automatic start/restart
- Short reaction time of just 10 ms, easy connection and time-saving mounting
- Detachable connection terminals for simple device swap-out
- Designs with screw terminals as well as with spring-cage terminals
MSI-RM2
Suitable up to category 4
With the MSI-RM2 relay module, a compact and – at the same time – economical solution is available in combination with safety sensors for applications up to Performance Level PLe. The relay module, only 17.5 mm wide, has two potential-free make contact circuits with a response time of only 10 ms.
- For converting electronic switch-off signals from safety sensors to potential-free, contact-based signals
- Detachable connection terminals for simple device swap-out
- Designs with screw terminals as well as with spring-cage terminals
MSI-DT
Delayed safeguarding
This safety relay with adjustable delay time is equipped with two release current paths which release undelayed in accordance with stop category 0. Two additional release current paths release in accordance with stop category 1 with adjustable delay time.
- Adjustable delay time (can be steplessly preset from 0.1…30 s)
- Monitoring of E-Stop buttons, safety doors, AOPDs
- Monitoring of safety circuits in accordance with DIN EN 60204?1/VDE 0113?1
- 1- or 2-channel wiring with cross-circuit detection
- Designs with screw terminals as well as with spring-cage terminals
- Two undelayed and two slow-release contacts
- Automatic and manual start circuit
- Detachable connection terminals for simple device swap-out
MSI-MC3x
Monitoring Magnetically Coded Sensors
MSI-MC300 safety relays are suitable for integration of MC 300 magnetically coded sensors in control circuits up to category 4 and Performance Level PLe in accordance with EN ISO 13849-1. These kinds of magnetically coded safety systems are used, for example, to monitor movable guards such as protective doors, sliding grids or flaps.
- Compact controller with long mechanical life time (10 million switching cycles)
- All Magnetically Coded Sensors (1NC/1NO) from Leuze electronic are connectable
- Automatic and start/restart operation
MSI-2H
Between man and machine
The MSI-2H is the link between two-hand command devices and the machine control. The device checks the simultaneous activation of the two, 2-channel buttons and ensures a controlled process start. The module is used everywhere that feeding-in is not automatic, but rather has to be performed manually by people.
- Two-hand control unit for presses, punching machines and other machines that are manually loaded
- Extended simultaneity monitoring for an increased level of acceptance of the safeguards,
- Can also be used as a safety door monitor acc. to EN 60204-1 STOP-0
- Detachable connection terminals for simple device swap-out
- Designs with screw terminals as well as with spring-cage terminals
MSI-CM
Expanded safety
The MSI-CM safety relay is used as a contact extension module in accordance with DIN EN 60204?1/VDE 0113 Part 1 for contact extension for E-Stop relays and two-hand control units. Depending on the wiring and proper integration of the feedback path, a Performance Level PL e in accordance with EN ISO 13849?1 is achieved.
- Contact extension module with extension block in accordance with DIN EN 60204-1/VDE 0113 Part 1
- Contact extension for E-Stop relays and two-hand control units
- 1- or 2-channel wiring
- Designs with screw terminals as well as with spring-cage terminals
- 5 release contacts, 1 signal contact, 1 feedback contact
- Detachable connection terminals for simple device swap-out
