SIL3/PLe security module for safe speed monitoring with two (different) encoder systems
SMC2.2 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 two sensors (HTL/proximity switch, RS422, SinCos) are supported for reliable speed detection.

Safety-M compact SMC2.2
The integrated signal converter and splitter allows an easy connection of controllers, which can operate using the same encoder system. It offers in addition the possibility of issuing an analog rotational speed value, e.g. to replace tachometers or similar.The device can be parameterized with a removable control and diagnostic display or with the PC software “OSxx“. This way, setting and diagnostic can be performed conveniently at the office PC or totally and easily using the intuitive touchpad display in the field.
- Extensive library of pre-configured safe sensors and command devices. This allows easy parameterizing without programming.
- Complete range of speed-related safe drive monitoring functions equivalent to EN 61800-5-2 already integrated in firmware (e.g. SOS, SLS, SSM, STO).
- Different encoder interfaces for TTL/RS422, SinCos and HTL/Push-Pull/proximity switch, for a wide range of sensors that can be freely combined.
- Integrated signal splitter for SinCos signal forwarding (optional). No complex, interference-sensitive external wiring when the controller is to use the same signals.
- The signal converter can issue the encoder signal as SinCos, TTL/RS422 or as a 4 ... 20 mA analog value.
- Snap-on installation on 35 mm C profile rail.
- 4/2 safe input lines, 8/4 safe shut-off channels, 1 safe potentialfree relay open contact.
- Contact multiplication or increase of power capability by external contactors in connection with the device-internal monitoring function for external contacts (EDM).
- LED on the front side indicates operating state.
- Removable control and diagnosis 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 |
