4-20 mA HART Loop Protocol
Although primarily a USB keyboard, the AIP827-2 integrates seamlessly into Yokogawa HIS environments where peripheral devices often rely on 4-20 mA HART loop communication. The keyboard’s design ensures compatibility with operator consoles that manage hybrid signal environments, maintaining channel-to-channel isolation and stable input recognition under varying load conditions.
Frequently Asked Questions (FAQ)
Q: Can the AIP827-2 be connected to non-Yokogawa PCs? A: It is designed for HIS stations; generic PC compatibility may vary.
Q: Does the keyboard support hot-swap via USB? A: Yes. The USB interface allows plug-and-play recognition within HIS systems.
Q: What environmental protections are applied? A: The keyboard is dust- and drip-proof, suitable for control room environments.
Field Installation Guidelines
Connect the keyboard via the USB A-type port to the HIS workstation.
Ensure AC supply voltage matches suffix code requirements before powering.
Place the keyboard on a stable console surface; adjust feet height if required.
Maintain ambient temperature within 5 to 40 deg C and humidity between 20 to 80 %RH.
Verify grounding of HIS system to prevent electrical interference.
