15 mm slice, 4 A at 60 °C — the panel-fit and load ceiling
The 6AG1132-6BF60-7AA0: At 73 mm tall and 58 mm deep, it fits standard control cabinet enclosures without crowding adjacent slices. The continuous output ceiling is 4 A per module at 60 °C ambient — that's the total current across all channels, not per point. The response threshold for short-circuit detection is 1.5 A typical, with built-in short-circuit protection that eliminates the need for per-channel fusing in most 24 VDC control circuits. Power loss is 1.5 W typical, which keeps the thermal contribution to the enclosure budget low even in a densely packed row of I/O slices.
DQ output, 300 µs on — timing and diagnostics for the control loop
The module provides DQ (digital output) with a 0-to-1 transition in 300 µs max and a 1-to-0 transition in 600 µs max. These switching times are fast enough for most discrete control sequences but not for high-speed PWM or oversampling — MSO and PWM are both listed as No, and oversampling is not supported. Diagnostics include a group error signal, diagnostic alarm, and per-module green/red DIAG LED plus per-channel green LED status display. I&M data from I&M0 through I&M3 is supported, which means the module can carry manufacturer, location, and maintenance identifiers readable over the backplane for asset tracking. The module is current-sinking (PNP sourcing is not supported), so confirm the load common matches a sinking output configuration. Redundancy capability is listed as Yes, which supports applications requiring a backup output path.
Active lifecycle — no obsolescence clock ticking yet
The module supports firmware updates (FW update possible), which extends its service life in the field as Siemens releases bug fixes or feature enhancements for the platform. Cable length limits are 1000 m shielded and 600 m unshielded — these are the maximum distances from the module to the field device, not the bus length. Plan the field wiring within these spans to avoid signal degradation or false triggers.
