PRODUCT DESCRIPTION
Compact digital I/O expansion in the CPU board slot
Siemens 6ES7223-0BD30-0XB0 is the SIMATIC S7-1200 SB 1223 signal board with two 24 V DC digital inputs and two 24 V DC digital outputs. It adds a small number of local signals through the compatible CPU's signal-board slot rather than a separate side-mounted module.
The inputs are current-sinking and the outputs are sourcing MOSFET channels, rated for loads within the documented limits. Check CPU compatibility, signal polarity, output current and protection before installation. Configure the board and its required operating behavior in the engineering project before returning the machine to service.

ACTUAL APPLICATIONS
Small I/O additions in S7-1200-controlled equipment
These scenarios draw on Siemens S7-1200 application materials. The signal board's proposed role is limited to compatible 24 V discrete signals; no source confirms this exact order code in the cited series examples.
-
01 · PUMP CONTROL SYSTEMS
Adding discrete status and command connections
In an S7-1200 pump-control station, a compatible SB 1223 can provide a small number of additional 24 V status inputs and command outputs. The PLC program performs the control logic, while suitable interposing equipment handles loads beyond the board's electrical ratings. -
02 · CONTAINER SORTING MACHINES
Connecting local detection and rejection signals
An S7-1200-controlled sorting machine may need a few extra discrete connections for compatible detection signals and actuator commands. This board supplies two inputs and two outputs when the CPU slot and project support it; it does not perform barcode recognition, weighing or motor-power switching itself. -
03 · WATER-BASED PROCESS EQUIPMENT
Extending a compact local control panel
For equipment using S7-1200 control in a water-supply or snowmaking process, the board can add compatible status contacts and low-power control commands inside a protected panel. Environmental suitability, circuit protection and the complete control design must be checked for the actual installation.

Manuals & support
SIMATIC S7-1200 / LOCAL SIGNAL-BOARD I/O
Match board-slot expansion to the field signal circuits
This SB 1223 occupies the supported signal-board position in the CPU. It adds local discrete channels but does not create a separate PLC or a networked remote-I/O station. Confirm the CPU and configured hardware support before wiring.
Follow the X19 assignment for the DC supply and four signal channels. Current-sinking inputs must be connected to compatible signal sources, while sourcing MOSFET outputs require loads and external protective measures within the published DC ratings.
Set the required input configuration and output response in the engineering project. In particular, verify the configured RUN-to-STOP behavior and test the external process response; a default value must not be assumed to make the complete machine safe.
Features:
- Exact article: 6ES7223-0BD30-0XB0
- Confirm the CPU board slot and configured hardware support
- Provide circuit protection within the output ratings
The Siemens 6ES7223-0BD30-0XB0 SB 1223 digital input/output signal board requires CPU support, signal polarity, connector assignment and output-load protection to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Keep the complete 6ES7223-0BD30-0XB0 article in replacement records. SB 1223 variants include different signal voltages and high-speed functions, so a shared board designation does not establish matching electrical behavior.
Disconnect the CPU and all S7-1200 equipment from electrical power before installing or removing the board. Record channel addresses, connector assignment and output-load protection, then inspect seating and wiring before controlled commissioning.
The reviewed catalog contains a future phase-out date of 1 November 2026. This draft does not describe the product as already discontinued or invent a replacement article. Recheck the current Siemens lifecycle record when ordering.
Features:
- Match the complete 6ES7223-0BD30-0XB0 article
- Match the standard SB 1223 article, not a high-speed variant
- Check sinking input polarity and sourcing output loads
The Siemens 6ES7223-0BD30-0XB0 SB 1223 digital input/output signal board requires replacement verification against CPU support, signal polarity, connector assignment and output-load protection before commissioning.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7223-0BD30-0XB0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Does this board mount beside the CPU like an SM module?
No. It fits the signal-board position in a compatible S7-1200 CPU. Siemens gives separate procedures for SB installation and side-mounted SM installation; confirm the available board slot before ordering. -
Are the digital inputs sourcing or sinking?
The two inputs are current-sinking inputs. The exact wiring table states that this board supports sinking inputs only. Match the external signal circuit and common reference to that arrangement. -
Can an output switch an AC load directly?
The outputs are sourcing MOSFET channels for the documented DC voltage range, not relay contacts. An AC load requires an appropriately engineered interface and protection; it must not be connected directly as if this were an AC relay board. -
What output load current is permitted?
The maximum is 0.5 A per channel, with a 1 A limit per common. Check load type and switching behavior as well: the manual specifies a 5 W lamp load limit and does not provide output overload protection. -
Can two outputs be paralleled for a larger load?
No. Siemens marks parallel connection for increased load and parallel connection for redundant load control as not permitted for this board. Use a suitable external interface or a correctly rated output device. -
What happens to outputs when the CPU changes from RUN to STOP?
The documented behavior is the last value or a configured substitute value, with zero as the default substitute. Verify the project setting and machine response rather than relying on an assumed shutdown state. -
May the board be inserted while the CPU is powered?
No. The installation and removal procedures require the CPU and all S7-1200 equipment to be disconnected from electrical power. Secure the process and follow the complete system instructions before working on the board. -
Which field connector pins are the input and output channels?
On X19, pins 1 and 2 are L+ and M. Pins 3 and 4 are DI e.0 and DI e.1; pins 5 and 6 are DQ e.0 and DQ e.1. Follow the exact-model diagram and configured addresses.
