Common Questions

• What is the HART protocol used for?

HART allows digital communication with smart field devices. It enables device configuration and diagnostics.

• How many input channels does this module have?

The module provides 16 fully isolated input channels. Each channel works independently.

• What is the measurement accuracy?

Accuracy is ±16 microamps across the entire 4-20 mA range. This ensures reliable data.

• Can I use 2-wire and 4-wire transmitters together?

Yes, you can mix transmitter types. Set each channel individually using configuration pins.

• What power supplies does the module need?

It requires both 5V DC (230 mA) and 24V DC (540 mA) power supplies for operation.
