Frequently Asked Questions (FAQ)

What makes this module different from basic analog inputs?

It supports the HART protocol, allowing you to access detailed diagnostic and configuration data from your smart field instruments directly through the 4-20mA loop.

Is the terminal board included?

No. The module includes the KS Cable Interface Adapter (ATK4A-00), which is designed specifically for connecting to the separate AEA4D Terminal Board.

Can I use it with old non-HART transmitters?

Yes. It is fully compatible with standard 4-20mA transmitters. The HART functionality is an added benefit for smart devices.

How do I set up the wiring for each channel?

Each channel has a setting pin that you must configure to match your transmitter, choosing either 2-wire or 4-wire mode.

Why is the high withstand voltage important?

The 1500V AC isolation protects your sensitive control system from dangerous voltage spikes that can occur in industrial environments, ensuring system safety.
