8 DIGITAL INPUTS · 8 RELAY OUTPUTS · 2 A CONTACTS
Siemens 6ES7223-1PH32-0XB0 SIMATIC S7-1200 SM 1223 Relay I/O Module
An SM 1223 mixed-I/O module combining sink/source inputs with eight mechanical relay outputs.
Overview
6ES7223-1PH32-0XB0 integrates eight IEC Type 1 digital inputs and eight relay outputs in a SIMATIC S7-1200 signal module. The 24 VDC input channels accept documented sink/source arrangements, while the relay contacts switch suitable AC or DC loads up to 2 A.
The relay execution consumes 11 mA per energized relay from the load supply and has different speed, lifetime and protection requirements from the transistor-output 1BH32 variant. The complete order number and STEP 7 hardware record therefore control substitution.
Specifications
Features
Two signal types in one module
Acquires eight field states while switching eight relay loads from the same S7-1200 expansion position.
Sink/source input support
Input commons can follow the approved field-device polarity documented for the machine.
Relay load range
Mechanical contacts support suitable AC or DC circuits rather than only 24 VDC sourcing loads.
Configurable input filtering
STEP 7 parameters can balance response speed and noise rejection for the connected sensors.

FAQ
Is 6ES7223-1PH32-0XB0 a transistor-output SM 1223?
No. It uses eight 2 A relay outputs; the 1BH32 version uses eight 0.5 A transistor outputs.
What information is needed to quote 6ES7223-1PH32-0XB0 correctly?
Send the full label, STEP 7 hardware entry, input polarity, output voltages, load currents, commons and enclosure photographs.
How should frequent switching be evaluated for 6ES7223-1PH32-0XB0?
Mechanical contact life depends on load and switching rate, so record the duty cycle and compare it with the manufacturer limits before approval.
Can 6ES7223-1PH32-0XB0 relay contacts switch both AC and DC loads?
Yes, within the published contact-voltage, current, lamp-load and suppression requirements for the actual circuit.
What proves 6ES7223-1PH32-0XB0 is commissioned correctly?
Verified input states, correct output addresses, stable commons, expected load operation and a completed point test establish the service record.
