Relays for functional safety Safety relays PNOZsigma PNOZ s50 Function description Introduction The PWM relay PNOZ s50 is used for the safety-related shutdown of inductive loads. It has two power outputs to activate two independent, inductive loads. Each power circuit is switched independently by two inputs. Two feedback loops monitor the switch status of the inductive loads. Two failsafe outputs signal the switch status of the inductive loads to the higher level safety control system.
Relays for functional safety Safety relays PNOZsigma PNOZ s50 Functions Switching the power circuits on and off (fast shutdown) The device has two safe dual-pole outputs O1+/O1- (power circuit 1) and O2+/O2-(power circuit 2), which can be switched using inputs Y10/Y11 (power circuit 1) and Y20/Y21 (power circuit 2): } } Switch-on (brake is ventilated): – O1+/O1- is switched on when there is a "1" signal (24 VDC) at Y10 and Y11.
Relays for functional safety Safety relays PNOZsigma PNOZ s50 Both poles are switched (e.g. O1+, O1-). O3 Fig.: Start-up condition for inputs Y10/Y11 After the output O1+/O1- and/or O2+/O2- is switched on, the voltage UB1B2 is available for a configurable overexcitation time Uover. Once the overexcitation time tover has elapsed, the voltage is reduced through pulse width modulation (PWM). The overexcitation time tover and the reduced voltage UAvg are configured via the display.
Relays for functional safety Safety relays PNOZsigma PNOZ s50 Switching the power circuits on and off (slow shutdown S35, S36) If the switching times are not critical, the loads at the power circuits can also be shut down slowly. A connected brake is permitted to have longer application times, for example. The brake switches with lower noise and is lower wearing. A 1/0 pulse edge at one of the slow shutdown inputs (S35 or S36) switches off the corresponding power circuit (O1+, O2+) in single-pole mode.
