16 INPUTS · 16 RELAY OUTPUTS · 2 A CONTACTS
Siemens 6ES7223-1PL32-0XB0 SIMATIC S7-1200 SM 1223 Relay I/O Module
The high-density relay SM 1223 pairing sixteen 24 VDC inputs with sixteen mechanical outputs.
Product Identification
6ES7223-1PL32-0XB0 combines sixteen 24 VDC sink/source inputs with sixteen relay outputs in the S7-1200 SM 1223 family. It is the relay counterpart to the 1BL32 transistor module and is intended for field circuits that fit the published mechanical-contact limits.
The module uses a 24 VDC supply from 20.4 to 28.8 V, draws up to 180 mA from the 5 V backplane bus and dissipates 10 W typically. Cabinet thermal planning and contact-load documentation are therefore important parts of the installed record.
Engineering Data

FAQ
Q01
Why should 6ES7223-1PL32-0XB0 not be confused with 6ES7223-1BL32-0XB0?
+
6ES7223-1PL32-0XB0 has 2 A relay outputs; 1BL32 has 0.5 A transistor outputs. Their load voltages, timing and protection are different.
Q02
What makes an 6ES7223-1PL32-0XB0 thermal review important?
+
Sixteen relay coils contribute to a typical 10 W power loss, so enclosure temperature and simultaneous operation must be considered.
Q03
Which records are essential before an 6ES7223-1PL32-0XB0 exchange?
+
Keep the STEP 7 archive, complete label, 32-point address map, load schedule, common wiring and cabinet thermal information.
Q04
Can 6ES7223-1PL32-0XB0 handle fast repetitive pulse duties like a transistor module?
+
Do not assume so. Mechanical relay lifetime and switching frequency must be evaluated for the actual load cycle.
Q05
How is an 6ES7223-1PL32-0XB0 service return demonstrated?
+
Correct input states, point-by-point relay operation, stable supplies, expected diagnostics and updated loop records complete acceptance.
