Safety relay modules SRB-E for a range of applications All versions of the family of safety relay modules PROTECT SRB-E can be used in applications up to Cat. 4 / PL e in accordance with ISO 13849-1 and up to SIL 3 in accordance with IEC 62061 / IEC 61508. A major advantage of the new SRB-E series is its multi-functionality which allows all the variants to be used with several existing SRB modules. Each module can be configured for up to 12 different applications via a simple control element. All conventional safety sensors and electromechanical safety equipment can be monitored. Adjustable...

Connection option for all standard safety switchgear Safe semi-conductor outputs Cat. 4 / PL e The PROTECT SRB-E-201ST variant is characterised by p-switching fail-safe performance semiconductor outputs with switching capacity of up to 5.5 A. This variant is particularly suited to fail-safe applications with high switching capacity in conjunction with short cycle times, for example switching valve terminals or complete output modules. Short cycle times → up to 60 switching cycles / minute Cycle times Very quick request response times Very short response times for SRB-E modules of less than...

Sealing the transparent front panel cover Once the rotary switch has been used to set the configuration required and commissioning is complete, the transparent front panel cover can be secured using a conventional seal. Equipment label The equipment label allows individual project and device assignment without additional organisational tools. This allows quick assignment of the electrical equipment in the event of maintenance work or trouble-shooting. Standard label signs can be glued or snapped into the space provided on the front of the housing. Ordering example: Connection Electronic...
