FAQs

How does this differ from a high-level analog input module?
The MU-TLPA02 is designed for millivolt-level signals (e.g., thermocouples) without pre-amplification, whereas high-level modules typically handle 4–20 mA or 1–5 V signals.

Does this module support STI communication?
No. This model is dedicated to low-level analog multiplexing. For STI support, consider the MU-TAIH series or compatible I/O processors.

Can it replace older MU-TLPA02 revisions?
Yes. The 51304467-100 is a standard replacement within TDC 3000 systems. Ensure proper software configuration for channel mapping.

Is the unit factory new?
Yes. It is supplied as a 100% brand new, factory-sealed unit in original Honeywell packaging to ensure full compliance with manufacturer specifications.
