2.1.2 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 dual­pole 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 single­pole failsafe output for error
– 2 single­pole failsafe outputs for status of the power circuits
– 2 test pulse outputs
– Potential of the single­pole outputs connected to supply voltage A1/A2
} Semiconductor inputs
– 4 failsafe inputs for activating the power outputs (fast shutdown of power circuits)
– 2 single­pole standard inputs for activating the power outputs (slow shutdown of
power circuits)
– 2 single­pole standard inputs for feedback loops
Potential of the semiconductor inputs connected to supply voltage A1/A2
} Supply voltage
– 24 VDC for device
– For power circuits, rated voltage 24 V, 48 VDC
Supply voltage for device and power circuit are isolated from each other
} Voltage output 24 VDC
Potential connected to supply voltage A1/A2
} Can be configured via the display on the device
} Configuration is stored on a chip card
