It accepts 0 to 20 mA, 4 to 20 mA, and -20 to +20 mA current signals, with a 125 Ω input resistance across all ranges, and supports both 2-wire and 4-wire transducer connections. Resolution reaches 16 bit including sign with overrange, and the module provides diagnostic alarms, limit value alarms, and a group error SF (red) LED for fault indication. ## Power draw and isolation The module draws up to 120 mA from the 5 V DC backplane bus and up to 20 mA from the load voltage L+ (without load), with a typical power loss of 1.5 W. Isolation is tested at 500 V between channels and backplane bus, and between channels and the power supply of the electronics, though there is no channel-to-channel isolation within the 8-channel group.","metaTitle":"Siemens 6ES7331-7TF00-0AB0 Analog Input Module, 8 AI HART","metaDescription":"Siemens 6ES7331-7TF00-0AB0 SIMATIC DP HART analog input SM 331, 8 AI, 0/4-20 mA, 16-bit.
