The Siemens 6AG1131-4BD01-7AB0 is a SIPLUS S7-1200 digital input module providing 4 channels rated for 24 V DC input, designed for the extended temperature range from -25°C to 70°C. Input signal threshold: a solid '1' at +11 V to +30 V, '0' at -30 V to +5 V. Typical input current is 8 mA per channel. The module draws 0.7 W from the backplane, leaving headroom for additional I/O modules. Diagnostics are onboard – a red group-error LED (SF) for fault indication, and electronically protected outputs against short-circuit to ground (module-by-module). The diagnostic function is parameterizable, as are input filter times (0.1 / 0.5 / 3 / 15 ms). Physical footprint is slim at 15 mm width, 81 mm height, 52 mm depth. Unshielded cable runs up to 600 m; shielded up to 1 000 m. Isolation tested at 500 V DC.

Frequently asked questions
What is the maximum operating temperature?
70 °C; = Tmax. That’s the upper limit for the extended SIPLUS range.
What is the minimum operating temperature?
-25 °C; = Tmin, well below standard S7-1200 limits for cold environments.
What compliance documentation does this module carry?
CE marking is confirmed; the module is tested for isolation at 500 V DC.
Does the module support diagnostics?
Yes – a red group error LED (SF) indicates faults, and short-circuit protection is electronic and can be enabled or disabled per module.
