6ES7422-1FH00-0AA0 | S7-400 SM 422 Digital Output 16× AC 120/230V 2A, Isolated
6ES7422-1FH00-0AA0 SIMATIC S7-400 SM 422 digital output module — 16 channels, 120/230 V AC, 2 A per channel, relay (triac) isolated groups, front connector 20-pin. For S7-400 central/expansion rack.

Product Overview

6ES7422-1FH00-0AA0​ is a SIMATIC S7-400 SM 422 digital output module​ providing 16 isolated AC output channels​ rated for 120/230 V AC at 2 A per channel (resistive load). It is designed to switch AC loads such as contactors, indicator lamps, solenoid valves (AC coils), and motor starters directly from the S7-400 PLC backplane. The 16 outputs are grouped into two isolated groups of 8 channels each (Group 0: Q0–Q7, Group 1: Q8–Q15), each with its own common (L/N) terminal. The module requires a 20-pin front connector (6ES7492-1AJ00-0AA0 or 6ES7492-1AL00-0AA0)​ for field wiring. Compatible with all S7-400 central racks (UR1/UR2) and expansion racks (ER1/ER2) via IM bus. Diagnostic LEDs indicate per-channel status and group power.

Key Features

  • Direct AC Load Switching:​ Eliminates need for intermediate interposing relays — switches 120/230 V AC contactors, solenoids, and indicators straight from the PLC.
  • Group Isolation (2 × 8 ch):​ Two electrically isolated groups allow separate AC supply phases or independent commons — simplifies panel wiring and fault isolation.
  • High-Current per Point (2 A):​ Each channel drives typical control relays/contactors directly — reduces auxiliary relay count in large panels.
  • Per-Channel Status LEDs:​ Immediate visual confirmation of which output is active — speeds troubleshooting during commissioning.
  • S7-400 Native Integration:​ Auto-detected by HW Config — no parameterization required for basic operation; diagnostic interrupt optional.

Typical Applications

  • Motor Starter / Contactor Control:​ Direct switching of AC coil contactors (up to 2 A) for pumps, conveyors, and compressors.
  • Solenoid Valve (AC Coil) Actuation:​ Pilot valves with 110/230 V AC coils in process skids and packaging lines.
  • Plant Annunciator / Beacon Drive:​ High-current lamp/beacon loads in MCC-integrated annunciation panels.
  • Retrofit / Expansion of S7-400 Systems:​ Adding AC DO points to existing S7-400 central or distributed (via IM467/PROFIBUS DP slave rack) configuration.
For DC 24 V output S7-400 modules see 6ES7422-1BL00-0AA0 (32×DC 24V/0.5A) or 6ES7422-1HH00-0AA0 (16×DC 24V/2A relay). For higher AC current or mixed I/O refer to ET 200M distributed I/O with SM 322 AC modules. Front connector (20-pin screw: 6ES7492-1AJ00-0AA0) and potential bridging set are ordered separately.
如需把之前其他产品(Yokogawa FU20,Festo DSBC/ADN,SMC AW40,ABB TZIDC,E+H FTL51B 等)也按此最终统一格式复核或重出,告诉我即可.
