Panel fit and output capacity
The 6AG1132-6HD01-7BB1: This is an 8-channel relay output module for the SIMATIC S7-1200 system — 20 mm wide, 73 mm tall, 58 mm deep. It snaps onto the standard DIN rail in the same footprint as the CPU and other signal modules, so it shares the backplane bus without extra wiring for the I/O data. Each relay output is rated 20 A continuous up to 40 °C, derating to 16 A at 50 °C and 60 °C. That current capacity is unusual for a compact S7-1200 module — it directly drives small motors, contactor coils, or valve solenoids without an interposing relay. The outputs accept both AC (230 V rated) and DC (24 V rated) loads, with channel-to-channel isolation and a tested isolation voltage of 2,500 V DC. This means mixed-voltage wiring in the same module is safe — one channel can switch a 24 V DC pilot light while another switches a 230 V AC contactor.
Sourcing and lifecycle for the BOM line
It uses the type B0 or base unit (BU) for the S7-1200 system, which is the same mechanical interface as the standard 6ES7132-6HD01-0BB0. The 6AG1 prefix indicates the SIPLUS variant, rated for extended temperature range and harsh environments — confirm the base unit part number separately if you are replacing a standard module.
Diagnostics and wiring notes
The module provides a diagnostic alarm and a green/red DIAG LED for module-level fault indication, plus a green LED per channel for status. That is enough to isolate a failed output without a handheld meter — the DIAG LED flashes on a short-circuit or wire-break condition. Power dissipation is 1.5 W typical — negligible for cabinet thermal budgeting, but worth noting if the module sits in a sealed enclosure with other high-current relay modules. The unshielded cable run is limited to 200 m; shielded cable extends that to 1,000 m.
