SIEMENS SIMATIC S7-1500 – 6ES7531-7KF00-0AB0
Overview
- 4, 8 or 16-channel analog input modules
- Optionally with extremely short conversion times
- For the connection of analog sensors without additional amplifiers
- Even solves more complex automation tasks
Application
Analog input modules record process signals such as pressure or temperature and forward them in digitalized format (16-bit format) to the PLC. They are suitable for measuring current (2-wire and 4-wire transducers), voltage, and resistance, as well as for the connection of resistance thermometers and thermocouples (measurement types depend on the module).

Design
- Mounting on the S7-1500 DIN rail using a single screw
- 35 mm modules: Standardized 40-pin front connector using screw terminal or push-in technology (cannot be used for 25 mm modules)
- 25 mm modules: Standardized 40-pin front connector using push-in technology (cannot be used for 35 mm modules)
- Connectable core cross-sections: 0.25Â mm2Â to 1.5Â mm2Â (AWG 24 to 16), regardless of front connector used
- Prewiring position of the front connector
- Front flap with expandable cable compartment, even if fully wired
- Integrated shielding concept (tool-free installation)
- Unambiguous labeling on the front of module:
- Module type
- Article number
- Hardware and firmware version
- Channel numbers labeling
- Cabling diagram
Included in the scope of delivery:
- Power supply element, shield bracket, and shield terminal
- One labeling strip for manual labeling
- One U connector
- Printed front door
Function
- Uniform display and diagnostics concept:
- Module status display for ERROR (red LED) and RUN (green LED)
- Channel status display (channel activated or deactivated, green LED) or diagnostics display (red LED)
- Display for monitoring the 24Â VÂ DC supply voltage (green LED)
- Supported functions:
- Consistently high resolution of 16 bits
- Identification and maintenance data IM0 to IM3
- Firmware update
- Channel-specific parameter assignment
- Hardware interrupts; two upper and two lower limits can be parameterized
- Channel-granular diagnostics (depends on measurement type/measuring range)
- Isochronous mode (dependent on the module)
- Calibration during runtime (dependent on the module)
