Frequently Asked Questions
Can this module read thermocouples directly?
Yes—it supports most thermocouple types (J, K, T, B, E, N, etc.) and RTDs via built-in cold-junction compensation.
Is HART communication supported?
Yes—the module includes HART AOP support for compatible field transmitters.
Can I replace while powered?
Yes—with RIUP lever capability—but you must turn off SA field power first to prevent arcing.
