FAQ
-
Does the AAI135-H53 support configuration through Yokogawa’s PRM (Plant Resource Manager)?
Yes, the module supports configuration and diagnostics via PRM, enabling access to HART device parameters. -
Can each channel support simultaneous analog and digital communication?
Yes, HART enables simultaneous analog signal transmission and digital diagnostics per channel. -
Is there redundancy support in this model?
Yes, when installed in a redundant I/O configuration, this module supports redundant signal processing. -
What is the input loop impedance, and why does it matter?
The input impedance is 250 Ω, critical for proper current loop operation and HART communication. -
How are faults communicated to the control system?
The module uses status flags, system alarms, and error codes visible in the engineering workstation. -
Does this module allow live hot-swap during operation?
No, it must be removed or installed with the system powered down to avoid potential disruptions. -
Can HART communication be disabled per channel?
Yes, HART can be enabled or disabled per channel depending on configuration requirements. -
Is there a built-in self-test mechanism?
Yes, the module performs continuous diagnostics and loop health monitoring. -
Can this module operate in environments with explosive gases?
Yes, with appropriate system certifications (ATEX, CSA), it can be used in Zone 2 environments. -
Is external signal conditioning required for other input types?
Yes, only 4–20 mA signals are accepted; voltage or thermocouple signals require conditioning.
