Product details

Module overview

The Siemens 6AG1550-1AA01-7AB0 is a TM Count 2x24V high-speed counting module for the S7-1500 system. It sits on the standard 35 mm mounting rail and occupies 35 mm width, 147 mm height, 129 mm depth. Power supply is 24 V DC with L+ minus 0.8 V tolerance, drawing 4 W typical. Two counter channels each handle 32 bytes input and 24 bytes output, switchable to fast mode for reduced data width.

Integration notes

Installs on S7-1500 mounting rail with 35 mm width. I&M data (I&M0 to I&M3) and diagnostic alarm support simplify commissioning. The RUN (green), ERROR (red), and MAINT (yellow) LEDs give immediate status. Isochronous mode and synchronization are available for coordinated multi-axis applications.

Frequently asked questions

What voltage supply does the 6AG1550-1AA01-7AB0 require?
