Product details

Panel fit and output ratings

The Siemens 6AG1522-1BH00-7AB0 is a 24 VDC transistor-output module for the S7-1500 platform. It delivers 4 A per group and 8 A per module, with a response threshold of 1 A and clocked electronic short-circuit protection. The 35 mm width fits a standard S7-1500 slot; the 129 mm depth and 147 mm height match the form factor of the rack.

Switching speed and diagnostics

Rise time (0→1) is 100 µs max; fall time (1→0) is 500 µs max. The module supports isochronous mode for deterministic update cycles and a fast startup of 500 ms. Diagnostic alarm and a red ERROR LED flag faults; the green RUN LED and channel-status LEDs give per-point visibility. I&M data (I&M0 to I&M3) is supported for asset tracking.

Frequently asked questions

Is 6AG1522-1BH00-7AB0 a replacement for 6ES7522-1BH00-0AB0?

The 6AG1522-1BH00-7AB0 is the SIPLUS variant of the standard S7-1500 output module. The standard order code is 6ES7522-1BH00-0AB0; the SIPLUS version adds extended temperature range and conformal coating for harsh environments. Confirm the BOM position and ambient conditions before substituting.
