The Siemens 6ES7142-4BD00-0AB0 is a 4-channel digital output module for the SIMATIC ET 200SP distributed I/O system, rated 24 VDC and 2 A per channel with per-channel short-circuit and wire-break diagnostics. Each output sinks 2 A at 24 VDC and triggers a short-circuit alarm at 2.8 A. The module handles inductive loads up to 0.5 Hz and resistive loads up to 100 Hz, covering solenoid valves and pilot lights reliably. Diagnostic feedback includes per-channel wire-break detection (resistance threshold 12 Ω to 4 kΩ) and short-circuit indication. The group error SF (red) LED on the module lights for any fault; the channel fault indicator F (red) pinpoints the affected output. Safety integrity is rated SIL 2 and Category 3.
Sourcing and logistics fit
The 35 mm depth and 45 mm width match the ET 200SP slot pitch. Power draw from the backplane bus is 30 mA and typical power loss is 2.5 W. For consignment or VMI programs, this part is a strong candidate: high standardization across ET 200SP installations, moderate turnover, and reliable supply channel.
Mounts on an ET 200SP base unit (BusAdapter required for the interface module). Wiring is via push-in terminals on the separate terminal module; the module itself is hot-swappable without rewiring the field cabling. Maximum cable length to the load is 30 m shielded or unshielded. Use the same cable run for both; the module does not require separate shielding for the output circuit. Reverse polarity protection is built in — the module withstands a reverse 24 VDC supply without damage. Substitute values can be set for failsafe operation.
