16 outputs, 24 VDC, with derating that governs real load
The Siemens 6ES7132-1BH00-0XB0 is a SIMATIC ET 200S digital output module packing 16 channels at 24 VDC nominal, with a total current ceiling of 4 000 mA up to 30 °C — that is 250 mA per channel if evenly loaded, but the real limit is the module total, not per-point. Above 30 °C the total drops to 2 A at 40 °C and 2 000 mA at 60 °C, so an enclosure running warm forces a load rebalance or a second module. The module fits a 145 mm wide by 60 mm tall by 60.5 mm deep footprint — standard ET 200S slice dimensions that slot into the DIN-rail mounted terminal block assembly.
Switching speed, protection, and wiring constraints
Outputs switch on in 50 µs max and off in 200 µs max, fast enough for most valve and contactor banks but not for high-speed indexing — the 100 Hz resistive load limit and 0.5 Hz inductive load ceiling confirm this is a general-purpose block, not a high-speed cam output. Short-circuit protection is built in, with a response threshold of 0.7 A typ, and the module signals diagnostics via the bus fault BF (red) LED. Reverse polarity protection is included on the supply, and the module draws 70 mA max from the backplane bus (L4+/L5+). Cable runs: shielded up to 1 000 m, unshielded up to 600 m — the unshielded figure is the one that bites in a noisy cabinet if you skip the screen termination.
