FAQ
-
Does the AAI135-H00/K4A00 support redundant configurations?
Yes, it supports redundant input channels when paired with appropriate I/O bases and configurations in CENTUM VP. -
Can I use voltage signals directly with this module?
No, the AAI135-H00/K4A00 is primarily designed for current (4–20 mA) input; using voltage inputs requires signal conversion. -
What is the input impedance von the analog channels?
The input impedance is typically 250 Ω per channel to accommodate standard 4–20 mA loops. -
Is HART communication enabled on all channels?
Yes, HART is supported on all 16 channels, provided proper wiring and settings are configured in the system. -
How does the module handle open-circuit detection?
The module includes diagnostics to detect wire breaks or disconnections in 4–20 mA loops and generates system alarms. -
What is the update rate for each channel?
The standard input scan time is around 100 ms per channel, which can vary depending on system load. -
Is channel-to-channel isolation provided?
Yes, the module provides galvanic isolation between individual channels to reduce signal interference. -
Can this module be used in SIL-rated safety applications?
Yes, when used within the Yokogawa ProSafe-RS system, it is suitable for SIL2/SIL3 applications depending on configuration. -
Are there limitations to mixing HART and non-HART devices?
No, the module can communicate with both HART-enabled and conventional 4–20 mA devices simultaneously. -
Is configuration required before commissioning?
Yes, the module must be configured using Yokogawa’s system svontware (such as PRM or SENG) before becoming operational.
