Product Overview
The SIMATIC SM 322 is a 16-channel 24 V DC digital output module for S7-300 and ET 200M installations, with diagnostic alarms and channel-level fault information.
Sixteen outputs switch 24 V DC loads at a rated 0.5 A per channel and include electronic short-circuit protection. The module can report wire break, short circuit and missing load voltage and provides red channel-fault indicators. The module can be used centrally with S7-300 CPUs or in documented ET 200M stations through compatible IM 153 interface modules.

Frequently Asked Questions
Can 6ES7322-8BH10-0AB0 be used in an S7-300 central rack?
The module can operate centrally with the available S7-300 CPUs.
Which ET 200M interface modules support 6ES7322-8BH10-0AB0?
Distributed use is supported with the specified IM 153-2 PROFIBUS variants and IM 153-4 PROFINET variants.
What load current can each channel of 6ES7322-8BH10-0AB0 switch?
Each output is rated for 0.5 amperes at 24 volts DC.
Which channel faults can 6ES7322-8BH10-0AB0 diagnose?
The module can identify wire break, short circuit and missing load voltage conditions.
How should long field cables be planned for 6ES7322-8BH10-0AB0?
The maximum cable length is 1,000 metres when shielded or 600 metres when unshielded.
Can two outputs on 6ES7322-8BH10-0AB0 be paralleled for a redundant load command?
Two outputs may be switched in parallel for redundant load control but not to increase current.
Which front connector is required for 6ES7322-8BH10-0AB0?
The module requires one 40-pin front connector.
Compatibility & Ordering Notes
Compatibility Checklist
- Use STEP 7 V5.5 with HSP0217 or a later supported engineering version.
- For distributed use, retain the compatible IM 153 hardware and the existing GSD or GSDML configuration.
- In redundant operation, use and configure the same module version in both positions.
