Siemens 3SK1111-1AB30 Safety relay Single channel

Siemens safety relay, 3SK1 series single channel, 24 V AC/DC power supply

Model feature introduction

SIRIUS3SK1 standard safety relay

The standard family of safety relays can be configured as stand-alone devices or as scalable solutions using traditional wiring techniques. The focus of the standard series is as follows: a single device is used for simple security applications, with output side expansion through expansion devices and external wiring. Unable to expand on input side.

application

Emergency close/emergency stop monitoring of protective doors, monitoring of non-contact protective devices with electromechanical position switches, solid state position switches or electromagnetic switches, such as light arrays/blockers or laser scanners

3SK1111 Standard Basic unit instantaneous (with relay output)

SIRIUS3SK1111 is a dual channel safety relay for emergency shutdown and emergency stop equipment, conforming to EN60204-1. The unit is equipped with a forward drive relay and monitors itself during each on/off cycle. The safety relay has three enable circuits (safety-dependent circuits) as normally open circuits and signal circuits (non-safety-dependent circuits, normally closed contacts). In the front of the 3SK1111 basic device, there is a sliding switch for function Settings; And two leds to show working status.

2 sensor inputs (channels 1 and 2) 1 input for feedback circuit and start button 3 enable circuits (safety-related circuit, normally open contact) 1 signal circuit (non-safety-related circuit, normally closed contact) 2 LED for display working status sliding switch, Used for function setting single channel or double channel connection sensor channel 1 and 2 Cross circuit detection housing width 22.5mm detachable terminal

3SK1112 Standard Basic Device Instantaneous (with solid state output)

The SIRIUS3SK1112 safety relay features two safety-dependent solid-state safety outputs and one non-safety-dependent signal circuit. At 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 set the load function and restart the device (reset). During the trial run, the 3SK1112 standard basic device ran through self-test. This checks that the internal electronics and firmware are working correctly. During operation, all internal safety-critical components of the circuit will be monitored in a loop for failure.

4-way DIP switch for function setting (parameterized) Set/reset button 4 leds, For status and function display 2 sensor inputs (channels 1 and 2) 1 input (cascade circuit) 1 input (start button circuit) 1 input (feedback circuit) 2 test outputs 2 safety solid state outputs 1 solid state signal circuit housing width 22.5mm detachable wiring terminals

The standard 3SK1 safety relay can be used in emergency shutdown/emergency stop equipment, conforming to ISO13850, and can be used in safety circuits, conforming to VDE0113-1 and/or DINEN60204-1. Depending on the external circuit, it can implement SILCL3, conforming to IEC62061; SIL3, in accordance with IEC61508; PLe (Type 4), consistent with ISO13849-1.
