properties
The PM-E F pp 24 VDC PROFIsafe power module has the following properties:
• Two relays for connecting voltage bus P2, 10 A output current
• Relay contacts must be fused externally
• 24 VDC rated load voltage
• Suitable for solenoid valves, DC contactors, and indicator lights
• Suitable for applications for which a grounded configuration is necessary or in which a
• Group fault display (SF; red LED)
• Status display for voltage bus P2 (green LED)
• Status display for load current power supply (PWR; green LED)
• Assignable diagnostics
• For achievable safety classes (safety integrity level), see following table

Switching the P2 Voltage Rail
The power module can switch the P2 voltage rail fail-safe with two series connected relay
contacts in accordance with AK4/SIL2/Cat.3 and AK6/SIL3/Cat.4. P2 is available as P on the
terminal module, P1 as M.
