Description

The LX3V-2PT2DAI-BD and LX3V-2PT2DAV-BD modules are high-performance thermal resistance input and output modules, designed to provide precise temperature monitoring and reliable analog output for industrial applications.

LX3V-2PT2DAI-BD features 2 channels of PT100 thermal resistance input, with a temperature compensation range from -100°C to 600°C and a 4-20mA analog output. It provides accurate temperature data with an overall accuracy of ±0.5%, 12-bit resolution, and a 50ms conversion rate.

LX3V-2PT2DAV-BD offers similar PT100 input capabilities, but with analog voltage output (-10V to 10V), allowing for greater flexibility in signal output. It provides a 16-bit resolution with a fast 50ms conversion rate and has an accuracy of ±0.5%.

Both modules are powered by a 24VDC or 5VDC supply (depending on model), making them suitable for integration into PLC systems for seamless operation.

Key Features:

  • LX3V-2PT2DAI-BD: PT100 input, 4-20mA analog output, accuracy ±0.5%, -100°C to 600°C range, 12-bit resolution.
  • LX3V-2PT2DAV-BD: PT100 input, -10V to 10V analog output, accuracy ±0.5%, 16-bit resolution, -100°C to 600°C range.
  • Analog output for both models: 12-bit binary, precision ±0.5% of full scale.
  • Fast AD conversion time: One PLC scanning cycle.
  • Powered by 24VDC (for analog) or 5VDC (digital)
  • No insulation between PLC channels.
