Product Description
Key Features
- Exact product identity: SIPLUS S7-300 SM 331 analog input module, based on 6ES7331-7KB02-0AB0, with conformal coating and -25…+70 °C.
- Analog input capacity: 2 analog inputs; 1 input is available for resistance measurement, and the analog inputs are not potential-separated from each other.
- Supported input types: Supports voltage, current, thermocouple, resistance thermometer, and resistance measurement, with parameterizable characteristic linearization.
- Supply and protection: Rated load voltage L+ is 24 V DC; reverse polarity protection is provided. Input current is max. 80 mA from L+ without load.
- Connection and diagnostics: 1x 20-pole connection; supports active-backplane-bus removing/inserting, diagnostic functions, diagnostic and limit value alarms, and a red group error SF LED.
Applications
- Voltage measurement: Measures voltage signals through supported voltage input ranges, including 1 V to 5 V, -1 V to +1 V, and -10 V to +10 V.
- Current measurement: Measures current signals through supported ranges including 0 to 20 mA, 4 mA to 20 mA, and -20 mA to +20 mA.
- Temperature and resistance measurement: Measures thermocouple, resistance thermometer, and resistance signals using supported sensor types and two-, three-, or four-wire connections.
