It accepts both 24 V AC and 24 V DC supply from the power module. The input thresholds are specified for signal 0 at -6 to +6 V DC or 0 to 5 V AC, and for signal 1 at -15 V DC to -57.6 V DC, 15 V DC to 57.6 V DC, or 15 V AC to 48 V AC. This wide range means the module can handle mixed-voltage field devices without separate input conditioners — a real time-saver when you're wiring a panel with both 24 VDC prox sensors and 48 VAC limit switches on the same slice. ## Sizing the slice and the signal chain At 15 mm wide and 52 mm deep, this module fits the standard ET 200S rail footprint — you can pack up to 16 of these across a 250 mm section. The 81 mm height clears most enclosures without a right-angle adapter. Each input draws a typical 10 mA at signal 1 (4 to 10 mA range), so the total module load at full saturation is about 40 mA from the field supply. The backplane bus draws a max of 10 mA at 3.3 V DC, leaving plenty of headroom on the power module's 500 mA rated capacity. Cable runs are rated up to 1 000 m shielded and 600 m unshielded, which covers most plant-floor distances without a repeater. ## Diagnostics and protection that save a service call The module includes parameterizable diagnostics with a group error SF (red) LED that flags a fault across all four channels. Each channel has its own green status indicator, so you can spot a missing sensor at a glance without plugging in a laptop. Short-circuit protection is built in per module, and reverse polarity protection is automatic for both AC and DC — meaning a swapped wire on a 48 VAC limit switch won't smoke the board. Isolation between the channels and the backplane bus is tested at 2 500 V DC, though there is no channel-to-channel isolation, so keep field wiring on the same potential group. The 2-wire sensor compatibility with a permissible quiescent current of up to 2 mA (0.5 to 2 mA) means it works with most standard proximity sensors; the fixed current limitation for wire-break monitoring uses an 18 kΩ resistor at 24 V or a 39 kΩ resistor at 48 V.","metaTitle":"Siemens 6ES7131-4CD00-0AB0 SIMATIC DP ET 200S","metaDescription":"Siemens 6ES7131-4CD00-0AB0 SIMATIC DP ET 200S electronic module: 4 digital inputs, UC 24V...48V, 15 mm width, 52 mm depth.
