Siemens 6ES7 148-4FC00-0AB0 SIMATIC S7 IO Module

Siemens 6ES7 148-4FC00-0AB0 is a PROFIsafe electronic module for the ET 200pro distributed I/O system, delivering four digital inputs and four digital outputs with 24 V DC operation (configurable for up to eight digital inputs in SIL2 mode or four inputs in SIL3 mode). It provides two short-circuit‑proof sensor supplies for each input, supports sensors such as switches and 3- or 4-wire proximity devices, and features four 2 A P/M‑switch outputs suitable for solenoids, DC contactors, and indicator lights, along with a group fault display and per-channel status/fault LEDs. Designed for safety-critical automation, it offers assignable diagnostics and identification data, and can achieve SIL3 when operated in safety mode within the ET 200pro framework.
