Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
Substance | Concentration |
Lead | 0.1% |
Mercury | 0.1% |
PBB (Polybrominated Biphenyls) | 0.1% |
PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
Hexavalent Chromium | 0.1% |
Cadmium | 0.01% |
DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
BBP (Benzyl butyl phthalate) | 0.1% |
DBP (Dibutyl phthalate) | 0.1% |
DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
SIRIUS 3SK1 Standard Safety Relay
The safety relays of the Standard series can be configured as stand alone devices or as an expandable solution with conventional wiring technology. The focus of the Standard series is on: single devices for simple safety applications, output side expansion by means of expansion units and external wiring. No expansion is possible on the input side.
Applications
Emergency Off / Emergency Stop monitoring
Monitoring of protective doors with electromechanical position switches, solid state position switches, or solenoid switches
Monitoring of contact free protection equipment, e.g. light arrays / light barriers, or laser scanners
3SK1111 Standard basic unit instantaneous (with relay outputs)
The SIRIUS 3SK1111 is a two-channel safety relay for EMERGENCY OFF and EMERGENCY STOP equipment in accordance with EN 60204-1. The unit is equipped with a positively driven relay and monitors itself during every ON/OFF cycle. The safety relay has three enabling circuits (safety related circuits) as NO circuits and a signalling circuit (non-safety related circuit, NC contact). On the front of the 3SK1111 basic unit there is a slide switch for function setting and two LEDs for displaying the operating states.
2 sensor inputs (channels 1 and 2)
1 input for feedback circuit and START button
3 enabling circuits (safety related circuits, NO contacts)
1 signalling circuit (non-safety related circuit, NC contact)
2 LEDs for displaying the operating states
Slide switch for function setting
Single channel or two channel connection
Cross circuit detection between sensor channels 1 and 2
Enclosure width 22.5 mm
Removable terminals
3SK1112 Standard basic unit instantaneous (with solid-state outputs)
The SIRIUS 3SK1112 safety relay has two safety related solid state safe outputs and one non-safety related signalling circuit. On the front of the safety relay there is a 4-way DIP switch for function setting and 4 LEDs for status and function display. The SET / RESET button is used to load function settings and to restart the unit (reset). On commissioning, the 3SK1112 standard basic unit runs through a self test. This checks that the internal electronics and firmware are functioning correctly. All internal safety critical parts of the circuit are cyclically monitored for faults during operation.
