Cold Junction Compensation & Channel Isolation
Designed for accurate temperature instrumentation, the MU-TAMR02 51304477-100 delivers precise RTD signal conversion utilizing a constant 1 mA sensor excitation current. The module architecture features high-stability analog-to-digital conversion with a temperature coefficient under +/-20 ppm per deg C, preventing thermal drift across variable ambient cabinet environments. Operating alongside 4-20 mA HART and millivolt process loops, internal channel isolation protects backplane processing logic against common-mode noise and input overvoltage conditions up to +2 V continuous.
Frequently Asked Questions
Q: What is the measurement resolution provided by the MU-TAMR02 51304477-100 RTD interface?
A: The board digitizes resistance inputs with a resolution of 8 milliohm per bit, enabling high-accuracy temperature calculation across RTD ranges.
Q: What continuous voltage limits can the input channels withstand without physical module damage?
A: The input channels tolerate continuous normal mode inputs ranging from -1 to +2 V at 100 mA without sustaining hardware damage.
Field Installation Guidelines
De-energize the I/O card file backplane before inserting or removing the MU-TAMR02 module.
Align the board edges with the target slot card guides and slide the unit inward until backplane bus contacts lock.
Terminate RTD field wiring to the corresponding termination assembly, ensuring 3-wire or 4-wire lead resistance balancing.
Ground cable shields at the single-point cabinet ground bus to eliminate inductive interference across temperature loops.
Apply backplane power and verify RTD sensor continuity and resistance readings via system diagnostic software.
