It accepts 24 V DC signals from switches, pushbuttons, or 2-wire proximity sensors. Each input is reverse-polarity protected and optically isolated from the backplane bus. The sensor supply output provides up to 500 mA total for the 2-wire loop — enough for four standard sensors at 7 mA each plus reserve. Compliance: CE marked, isolation tested at 500 V DC. ## Input characteristics and field wiring Signal '0' threshold: -30 to +5 V. Signal '1' guaranteed from +15 to +30 V. Typical current draw per channel at 24 V is 7 mA. Response time 2 ms to 4.5 ms for both on-to-off and off-to-on transitions — fast enough for most discrete sensing but not encoder tracking. Module dimensions: 15 mm wide, 81 mm high, 52 mm deep — fits one S7-1200 signal slot. Maximum sensor cable length 1 000 m shielded, 600 m unshielded. Address space 1 byte; parameterization not supported (fixed configuration).","metaTitle":"Siemens 6AG1131-4BD01-2AA0 SIPLUS S7-1200 SM 1221 4DI, 24V D","metaDescription":"SIPLUS digital input module for S7-1200, 4 channels 24 V DC, 2-wire sensor compatible, 500 mA sensor supply, -25 to 60 °C.
