Unit features
Using the product PNOZ s50:
PWM relay for the safe activation of inductive loads, e.g. valves, mechanical holding
brakes.
The product has the following features:
} Semiconductor outputs
– 2 dual-pole failsafe power outputs, rated voltages 24V or 48VDC, e.g. for mechan-
ical holding brakes, valves
– Output voltage can be reduced through pulse width modulation (PWM)
– Potential of the power outputs connected to the supply voltage B1/B2
– 1 single-pole failsafe output for error
– 2 single-pole failsafe outputs for status of the power circuits
– 2 test pulse outputs
– Potential of the single-pole outputs connected to supply voltage A1/A2
} Semiconductor inputs
– 4 failsafe inputs for activating the power outputs (fast shutdown of power circuits)
– 2 single-pole standard inputs for activating the power outputs (slow shutdown of
power circuits)
