Siemens 6ES7222-1BH32-0XB0 SM 1222 16-Point Transistor Output Module
A higher-density SM 1222 transistor module for sixteen documented 24 V DC output circuits.
Product Overview
Siemens 6ES7222-1BH32-0XB0 is the sixteen-output SM 1222 transistor module for SIMATIC S7-1200. Each published channel is rated at 0.5 A under the specified conditions.
The sixteen-point density differs from the eight-output 1BF32 unit and the eight-relay 1HF32 unit. Project addressing, group current, connector allocation and thermal loading must remain tied to this exact MLFB.
Siemens lists a 0.198 kg net weight and an 8.80 × 10.80 × 5.70 cm package for the catalog number.
Performance
Sixteen actuator commands
Drives a larger set of 24 V DC loads from one S7-1200 signal module.
Solid-state switching
Provides transistor behavior appropriate for documented DC loads and switching duties.
Grouped load management
Requires total group current and common routing to remain inside the engineered design.
Project-linked diagnostics
Keeps each field output associated with its TIA Portal assignment and service evidence.

IndustryParts keeps the complete model label, requested quantity, application evidence and delivery requirements together so the proposed supply can be checked against the installed system before dispatch.
System Integration
Build the sixteen-point schedule
Map tags, terminals, commons, fuse paths and actuator loads before isolation.
Check cumulative loading
Review channel and group currents plus cabinet thermal conditions rather than considering channels independently.
Prove safe sequencing
Test outputs in an approved order so valves, motors and interlocks cannot create an unsafe transition.
Applications
High-count machine control
Operating multiple 24 V DC solenoids, contactor interfaces and indicators.
Panel consolidation
Using one sixteen-point module where the rack and wiring were designed for the density.
Planned maintenance
Replacing the exact transistor article without converting to relay technology.
FAQ
Q01
How does 6ES7222-1BH32-0XB0 differ from 6ES7222-1BF32-0XB0?
+
Both use 24 V DC transistor outputs, but 6ES7222-1BH32-0XB0 provides sixteen channels instead of eight.
Q02
Why can an eight-relay module not be assumed equivalent to 6ES7222-1BH32-0XB0?
+
Relay contacts change voltage capability, delay, protection, switching life and wiring.
Q03
What load schedule is required for 6ES7222-1BH32-0XB0?
+
List all sixteen actuators with steady current, inrush, suppression, switching frequency and output group.
Q04
What should be checked if one 6ES7222-1BH32-0XB0 group overheats?
+
Review cumulative group loading, conductor condition, cabinet temperature and duty cycle before replacing hardware.
Q05
What demonstrates a successful 6ES7222-1BH32-0XB0 exchange?
+
All sixteen commands, de-energized states, diagnostics, interlocks and safe-state responses match the released test plan.
