All conventional safety switches can be monitored for 11 different applications
The multifunctional safety relay modules of the Schmersel PROTECT SRB-E series are mainly used for the construction of safety circuits and are suitable for installation in control cabinets.
The multifunctional safety relay module PROTECT SRB-E meets the application requirements of safety category 4/PL e according to EN ISO 13849-1 and SIL3 according to EN 62061/IEC 61508S.
One of the main advantages of the PROTECT SRB-E series of safety relays is their versatility, allowing them to be used with dozens of existing SRB safety relay modules. Each module can be configured with a simple control element and is suitable for eleven different applications. Almost all common security devices can be monitored.
Single- or dual-channel applications can be monitored for the following safety devices:
Electromagnetic door locks in accordance with ISO 14119
Safety limit switches according to IEC/EN 60947-5-1
Safety sensors in accordance with EN 60947-5-3
Emergency stop devices in accordance with DIN EN ISO 13850 (EN 418) and EN 60947-5-5
Safety magnetic sensor in accordance with EN 60947-5-3
Safe optoelectronic devices in accordance with EN IEC 61496
Hand control test according to EN 574 Type IIIC
Special design features
1. Front-facing configuration app
Use the knob switch for simple setup
2. Seal the transparent front panel cover
Once the application is selected, it can be secured with seals
3. Slotted terminals
With anti-misinsertion coding
4. Device tags
It can be used to paste the device tag
5. Diagnosis/Status/Visualization
Use LEDs to display the status of the signal; Use flashing signals to indicate the source of errors and faults
6. Compactness
All modules have an installation width of only 22.5 mm and 24 terminal blocks
7. Important features
Safety Semiconductor Output, Category 4/PL e
The SRB-E-201ST features a p-type switch fail-safe performance semiconductor output with a switching capacity of up to 5.5A. This model is particularly suitable for fail-safe applications where the high exchange capacity is combined with short cycle times, such as changeover valve terminations or complete output modules.
Very fast response time
The SRB-E module has a very short response time of less than 10ms from the time the device is protected to the time the safety output is turned off.
