SIL3/PLe security module for safe speed monitoring with two (different) incremental encoder systems/sensors
SMC2.4 is a compact safety module in the Safety-M family with integrated drive monitoring for one axis with two (different) encoder systems. This standalone speed monitor (base module) does not require an additional safe PLC.
Safety-M compact is perfect for integration into existing safety circuits or for upgrading old machines. Solutions with a two sensors (HTL differential, HTL single ended/proximity switch, RS422) are supported for reliable speed detection.

Safety-M compact SMC2.4
The integrated signal converter and splitter makes it easy to connect controllers that can work with the same encoder system. In addition, it is possible to output an analog speed value, e.g. for the replacement of tachometers or similar.
The device can be parameterized using a removable operating and diagnostic display or the “OSxx“ PC software. Diagnostics and settings can be made comfortably from the office PC but also completely and easily using the intuitive touchpad display in the field.
- Extensive library for preconfigured safety sensors and control devices. This allows easy parameterization with no programming.
- Complete speed-related safety functions for drive monitoring equivalent to EN 61800-5-2 integrated in firmware (e.g. SOS, SLS, SSM, STO).
- Various encoder interfaces: HTL differential, HTL single ended, RS422, or proximity switches, for a wide range of sensors, freely combinable with each other.
- Integrated signal splitter for forwarding the encoder signals (optional). No complex, interference-prone external wiring if the controller wants to use the same signals.
- The signal converter can output the encoder signal as HTL differential, HTL single ended, RS422, or as analog values from 4 to 20 mA.
- Simple mounting, snaps onto 35 mm C-profile rail.
- 8/4 safe inputs, 8/4 safe shutdown channels, 1 safe dual-channel potential-free relay contact
- Contact multiplication or contact amplification by external contactors in connection with integrated monitoring possible (EDM).
- The front LED always shows the operating status.
- Removable operating and diagnostic display (optional).
- Free “OSxx“ parameterization software.

Pluggable operating and diagnostic display for the Safety-M compact family.
The SMCB display is used as a display and control unit for the Safety-M compact modules. Thanks to its intuitive operation, the SMCB display can be used quickly, easily and flexibly. The SMCB display can be used directly on the safety device. A multitude of functions and application possibilities are available.| 8.SMCB.100 |
