8.2.1 Properties of the 4/8 F-DI/4 F-DO DC24V/2A PROFIsafe Electronic Module
Order Number
6ES7 148-4FC00-0AB0
Properties
The 4/8 F-DI/4 F-DO DC24V/2A PROFIsafe electronic module has the following properties:
●
Inputs
–
8 inputs (SIL2/Category 3) or four inputs (SIL3/Category 3 or Category 4)
– 24 V DC rated input voltage
– Suitable for switches and 3- or 4-wire proximity switches (BEROs)
– Two short-circuit-proof sensor supplies for each of the four inputs
– External sensor supply possible
● Outputs
–
Four outputs, P/M switching (current sourcing/sinking)
– 2 A output current
– 24 V DC rated load voltage
– Suitable for solenoid valves, DC contactors and indicator lights
● Group fault display (SF; red LED)
● Fault LED for each sensor supply (Vs1F to Vs2F) is mapped to VsF LED and the
associated channels.
● Status and fault LEDs for each input/output (two-color green/red LED)
● Identification data (
see ET 200pro Distributed I/O System Standard Manual)
● Assignable diagnostics
● Safety class SIL3 achievable
● Can only be operated in safety mode
