Two channels configurable for 0(4)-20 mA or ±20 V outputs, 12-bit resolution plus sign. Diagnostics per channel cover wire-break and short-circuit, with a red group error LED and parameterizable diagnostic alarm. Crosstalk between outputs is at least 45 dB; cycle time max 1 ms. Resolution with overrange is 11 bit plus sign, linearity error ±0.08%, repeat accuracy ±0.05%. For current outputs, maximum load is 500 Ω; for voltage outputs, two-wire connection supported. ## Integration notes Power draw: typical 2.3 W, max 110 mA from L+. Supports S7 or S5 analog value format; data exchange happens within the ET200X backplane. Connect via two 5-pin M12 connectors for the outputs.","metaTitle":"Siemens 6ES7145-1GB31-0XB0 SIMATIC DP EM 145, 2 AO, M12, IP6","metaDescription":"Current-production SIMATIC DP expansion module for ET200X. 2 analog outputs, ±20V/0(4)-20mA, 12-bit+sign, diagnostics per channel, M12 connectors, IP66/67.
