Module overview
The Siemens 6AG1134-6TD00-2CA1 is a 4-channel analog input module for the S7-1200 F failsafe system, accepting 4-20 mA signals with 15-bit plus sign resolution across differential inputs. It operates on a 24 V DC rated supply, drawing 25 mA max without sensor power, and consumes 0.65 W typical.
Diagnostics per channel
Each channel can report wire-break (4 mA > wire-break threshold) and short-circuit (input or encoder supply to ground) individually. Diagnostic and limit-value alarms are generated, with a dedicated group error output.
Mounting and wiring
Module width is 15 mm, depth 58 mm, height 73 mm, and it mounts on a DIN rail via BU type A0 or A1 base units. Maximum cable length for shielded twisted pair is 800 m.
