They are used for the safe evaluation of the signals of positive break position switches or magnetic safety sensors for safety functions on sliding, hinged and removable safety guards as well as emergency stop control devices and AOPD's. The safety function is defined as the opening of the enabling circuits 13-14, 23-24 and 33-34 when the inputs S11-S12 and/or S21-S22 are opened. The safety-relevant current paths with the outputs contacts 13-14, 23-24 and 33-34 meet the following requirements under observation of a PFH value assessment (also refer to chapter 2.5 "Safety classification"): – Control category 4 - PL e to DIN EN ISO 13849-1 – SIL 3 to DIN EN 61508-2 – SILCL 3 to DIN EN 62061 (meets the requirements of control category 4 to DIN EN 954-1) To determine the Performance Level (PL) of the entire safety function (e.g. sensor, logic, actuator) to DIN EN ISO 13849-1, an analysis of all relevant components is required. 2.4 Technical data General data Standards: IEC/EN 60204-1, EN 60947-5-1; EN ISO 13849-1, IEC 61508 Climate resistance: EN 60068-2-78 Fixing: Snaps onto standard DIN rails to DIN EN 60715 Terminal designations: EN 60947-1 Material of the enclosure: glass-fibre reinforced thermoplastic, ventilated Material of the contacts: AgSnO, self-cleaning, positive drive Weight: 230 g Start conditions Automatic or start button Feedback circuit (Y/N): Yes Pull-in delay for automatic start: typ. 100 ms Pull-in delay with reset button: typ. 20 ms Drop-out delay in case of emergency stop: typ. 20 ms Drop-out delay on "supply failure": typ. 80 ms Bridging in case of voltage drops: typ. 80 ms Mechanical data Connection type: Screw terminals Cable section: min. 2 mm² / max. 2 mm² Connecting cable: rigid or flexible Tightening torque for the terminals: 0.6 Nm With removable terminals (Y/N): No Mechanical life: 10 million operations Electrical life: Derating curve available on request Resistance to shock: 10 g / 11 ms Resistance to vibrations to EN 60068-2-6: 10 ... 55 Hz, amplitude 0.35 mm Ambient conditions Ambient temperature: –25°C … +60°C Storage and transport temperature: –40°C … +85°C Protection class: Enclosure: IP 40, Terminals: IP 20, Wiring compartment: IP 54 Air clearances and creepage distances to IEC/EN 60664-1: 4 kV/2 (basic insulation) EMC rating: to EMC Directive Electrical data Contact resistance in new state: max. 100 mΩ Power consumption: max. 2.0 W / 4.9 VA Rated operating voltage Ue1: 24 VDC –15%/+20%, residual ripple max. 10% 24 VAC –15% / +10% Frequency range: 50 Hz / 60 Hz Max. fuse rating of the operating voltage: internal electronic fuse, tripping current > 500 mA, reset after approx. 1 sec.

Device dimensions (H/W/D): 100 x 22.5 x 121 mm 4 Electrical connection 4.1 General information for electrical connection As far as the electrical safety is concerned, the protection against unintentional contact of the connected and therefore electrically interconnected apparatus and the insulation of the feed cables must be designed for the highest voltage, which can occur in the device. The electrical connection may only be carried out by authorised personnel in de-energised condition. Wiring examples: see appendix 5 Operating principle and settings 5.1 LED functions • K1: Status channel 1 • K2: Status channel 2 • UB: Status operating voltage (LED is on, when the operating voltage on the terminals A1-A2 is ON) • Ui: Status internal operating voltage (LED is on, when the operating voltage on the terminals A1-A2 is ON and the fuse has not been triggered) 5.2 Terminal description (see Fig. 1) Voltages: A1 A2 +24 VDC/24 VAC 0 VDC/24 VAC Inputs: S11-S12 S12-S22 S21-S22 Input channel 1 (+) Input channel 2 (+) Input channel 2 (–) (with cross-wire short detection) Outputs: 13-14 23-24 33-34 First safety enabling circuit Second safety enabling circuit Third safety enabling circuit Start: X1-X2 41-42 Feedback circuit and external reset Auxiliary NC contact 5.3 Notes Signalling outputs must not be used in safety circuits. Due to the operating principle of the electronic fuse, the customer must check that no hazard is caused by an unexpected restart in circuits without reset button (automatic reset). Opening the front cover (see Fig. 2) • To open the front cover, insert a slot screwdriver in the top and bottom cover notch and gently lift it. • When the front cover is open, the electrostatic discharge requirements must be respected and observed. • After the setting, the front cover must be fitted back in position. Only touch the components after electrical discharge! Setting the switch (see Fig. 3) • The cross-wire short monitoring function (factory setting) is pro- grammed by means of the switch underneath the front cover of the safety-monitoring module. • The switch must only be operated in de-energised condition by means of a finger or an insulated blunt tool. • Pos. nQS (top), not cross-wire short proof: suitable for 1-channel applications and applications with outputs connected to potential in the control circuits. • Pos. QS (bottom), cross-wire short proof: suitable for 2-channel applications without outputs connected to potential in the control circuits.

External reset button (non-monitored start) (see Fig. 5) • The external reset button is integrated in the feedback circuit in series. • The safety-monitoring module is activated upon actuation of the reset button. Automatic start (see Fig. 6) • The automatic start is programmed by connecting the feedback circuit to the terminals X1/X2. If the feedback circuit is not required, establish a bridge. • Caution: Not admitted without additional measure due to the risk of gaining access by stepping behind! • When the SRB 301MC safety-monitoring module is used with the operating mode "Automatic start", an automatic restart after a shutdown in case of emergency must be prevented by the upstream control to EN 60204-1 paragraph 9.2.5.4.2. Due to the operating principle of the electronic fuse, the customer must check that no hazard is caused by an unexpected restart in circuits without reset button (automatic reset).
