Properties of the PM-D F DC24V PROFIsafe Power Module

Order Number
3RK1903-3BA02
Properties
The PM-D F DC24V PROFIsafe power module disposes of the following properties:
● 6 shutdown groups, SG 1 through SG 6
● Output current of SG 1 through SG 6, each 3 A (total current 5 A)
● Rated load voltage 24 VDC per shutdown group
● Suitable for supplying:
● Group fault display (SF; red LED)
● Status display per shutdown group (SG 1 through SG 6; green LED)
● Status display for load current power supply (PWR; green LED)
● Status display for electronic power supply (U1; green LED)
● achievable safety class SIL3/Category 4/PLe
Switching the Voltage Buses SG 1 through SG 6 and U 1
The power module can shut down voltage buses SG 1 through SG 6 over 6 digital outputs
complying with safety class SIL2/Category 3/PLd or SIL3/Category 4/PLe. The outputs are
implemented with two P switches. There is a main switch for all 6 shutdown groups and 6
individual switches connected in series per shutdown group.
The voltage bus U 1 (electronics power supply for the motor starters) is supplied with
24 VDC. When overvoltage or undervoltage occurs, U 1 is switched off by two P switches
and the downstream motor starters are passivated. In the event of a safety shutdown of
motor starters, U 1 is not switched off.
