Siemens 6ES7422-1BL00-0AA0 is a SIMATIC S7-400 SM 422 isolated digital output module with 32 channels rated for 24 V DC loads up to 0.5 A per channel.
The module switches field actuators from the S7-400 backplane and uses grouped load-voltage connections. Observe the official current, short-circuit, inductive-load and group-loading limits when wiring outputs.
The product is in Siemens phase-out status. Verify rack, connector, load supply, fuse strategy and STEP 7 configuration before replacing an installed module.
The Siemens 6ES7422-1BL00-0AA0 may be supplied and supported by Moore Automated according to the official product lifecycle: Active/Available from OEM.

SM 422 switches thirty-two 24 V DC loads from an S7-400 rack. Correct operation depends on grouped load-supply wiring, per-channel and group current limits, protection for inductive loads and matching STEP 7 parameters; isolate field power before connector work.
Compatibility: It requires a compatible SIMATIC S7-400 rack, correct front connector and 24 V DC field load supply within the module current limits.
Configuration: Remove rack and field power, verify group supply polarity and load current, apply suitable suppression for inductive loads and test channels after configuration.
Application: It drives relays, solenoids, indicators and other 24 V DC actuators in S7-400 control systems.
Lifecycle: Siemens lists 6ES7422-1BL00-0AA0 in phase-out status; confirm ordering and migration strategy.
