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. ApplicationsEmergency Off / Emergency Stop monitoringMonitoring of protective doors with electromechanical position switches, solid state position switches, or solenoid switchesMonitoring 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 button3 enabling circuits (safety related circuits, NO contacts)1 signalling circuit (non-safety related circuit, NC contact)2 LEDs for displaying the operating statesSlide switch for function settingSingle channel or two channel connectionCross circuit detection between sensor channels 1 and 2Enclosure width 22.5 mmRemovable 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.4-way DIP switch for function setting (parameterization)SET / RESET button4 LEDs for status and function display2 sensor inputs (channels 1 and 2)1 input (cascading circuit)1 input (START pushbutton circuit)1 input (feedback circuit)2 test outputs2 safe solid state outputs1 solid state signalling circuitEnclosure width 22.5 mmRemovable terminals Standards The 3SK1 safety relay can be used in Emergency Off / Emergency Stop devices in accordance with ISO 13850 and in safety circuits in accordance with VDE 0113-1 and/or DIN EN 60204-1. Depending on the external circuit, it is possible to achieve SILCL 3 in accordance with IEC 62061, SIL 3 in accordance with IEC 61508 and PL e (Cat. 4) in accordance with ISO 13849-1. Safety Relay |
