Product Features

• 8-Channel Analog Input:
  Supports 8 analog current input channels, suitable for industrial control systems that require multiple analog signals. Each input range is configurable to either 0-20 mA or 4-20 mA, adapting to different sensors and application requirements.

• Precision and Resolution:
  The module features a 12-bit digital resolution with an analog resolution of 5.0 microamps, ensuring precise current measurements, especially effective for processing small signals.

• Built-In Diagnostics:
  Integrated diagnostics provide over-range and open-wire detection for 4-20 mA loops. Fault conditions such as over-range input or broken wires are indicated through status LEDs, ensuring system reliability.

• Input Filtering and Signal Conditioning:
  Each input channel is equipped with an RC filter to suppress high-frequency noise. Operational amplifiers are used to buffer the input signals, enhancing stability before passing them to the analog-to-digital converter (A/D Converter).

• Independent Power Supply Design:
  The input channels are powered by a 24V DC supply, which can be shared with the Bus Interface Unit or supplied separately for isolation, offering greater flexibility in field wiring.

• Over-Voltage Protection:
  Each input channel has built-in over-voltage protection, with typical over-range fault indication ranging from 20.000 mA to 20.500 mA, ensuring the module remains undamaged in case of faulty inputs.
