Signal module for high-speed counting and positioning
The 6ES7223-7AF50-0XB0 is a SB 1223 signal board for the SIMATIC S7-1200 G2 controller, packing four 5 V DC digital inputs and four 5 V DC digital outputs, all switching at 200 kHz. Each output is rated 0.1 A, transistor type, configurable as sinking or sourcing — this matters when the field device expects a specific current-sourcing topology, common on high-speed pick-and-place or encoder interfaces. The 200 kHz input frequency suits applications like counting fast-moving parts on a conveyor or reading incremental encoders directly, without a separate high-speed counter module.
Active lifecycle and compliance documentation
Siemens lists the 6ES7223-7AF50-0XB0 as current production — no end-of-life notice or successor has been issued, so it remains a standard BOM line for new S7-1200 G2 builds. RoHS compliant since 22-01-25, with a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w — this is typical for leaded solder terminations on the PCB and does not affect the module's functional compliance for industrial installations. Export control classification is AL: N / ECCN: EAR99H, meaning no special licensing is required for most commercial shipments outside embargoed destinations.
Physical fit and packaging
Packaged as a single piece in a box measuring 82 x 34 x 79 mm — the signal board form factor snaps onto the front of the S7-1200 G2 CPU, adding no extra DIN-rail width. Product class A means it is a standard stock item eligible for return within the stated guidelines — useful for panel builders ordering a spare for the kit.
