For all types of electronics modules (including safety-related electronics modules); limitations resulting from the supply voltage for PM?E DC 24 V
For monitoring and – depending on the version – fusing the power supply for electronics modules provided via the TM?P terminal module (load and sensor power supply)
Diagnostics signals for voltage and blown fuse (can be switched off in the configuration)
Three versions with different supply voltages:
PM-E 24 V DC (not for 2 DI 120 V AC Standard, 2 DI 230 V AC Standard, and 2 DO 24 to 230 V AC)
PM-E 24 V DC High Feature with extended status information (not for 2 DI 120 V AC Standard, 2 DI 230 V AC Standard, and 2 DO 24 to 230 V AC)
PM-E DC 24 to 48 V; AC 24 to 230 V; with additional fuse
PM-E F power module
For all non-safety-related types of electronics modules with 24 V DC power supply
For monitoring the power supply for electronics modules provided via the TM?P terminal module (load and sensor power supply)
For safe switching off of series-connected digital output modules 24 V DC (up to 10 A; not safety-related) via relay contacts (up to Cat. 3 in accordance with EN 954 or SIL 2 in accordance with IEC 61508); released output modules are specified on the Internet at: https://support.industry.siemens.com/cs/ww/en/view/39198632
Design PM-E F pm DC 24 V PROFIsafe for floating loads (ground and earth separated); with two additional safety-related digital outputs (switching to high/low, up to SIL 3) Diagnostics functions:
Module: overtemperature, internal fault, parameterization error, sensor/load voltage missing, communication fault
Design PM-E F pp DC 24 V PROFIsafe for non-floating loads (ground and earth connected), e.g. actuators for connection to a central ground (switching to high/high, up to SIL 3) Diagnostics functions:
Channel: short-circuit, safety-related shutdown
Module: overtemperature, internal fault, parameterization error, sensor/load voltage missing, communication fault
