- Eight field pulse-input circuits for the PPIX02 processor.
- Compression terminations for the documented sensor and contact arrangements.
- Waveform, cable length and filter settings determine usable pulse frequency.
Honeywell MU-TPIX12 is the field termination assembly for eight PPIX02 pulse-input circuits. The published processor/FTA table includes self-powered two-wire sensors, system-powered three-wire sensors, pulse-voltage signals and contact inputs. Rectangular and sine-wave signals are specified, but the manufacturer prohibits mixing sine waves with square waves or contacts on the same FTA. Compression terminals provide the field connections on the uncoated size-B board; the associated processor performs rate measurement and totalization.
The headline frequency range is 1 Hz to 20 kHz under the stated conditions. With mixed signal amplitudes, the allowed maximum falls with FTA cable length, reaching 9 kHz for a 50 m cable. Filter-jumper settings also change the minimum pulse dwell and usable frequency. The specification gives a 20 ms field scan and 500 ms process-value update for eight channels. These are system processing figures, not independent timing guarantees from a passive terminal connection.
The MU-TPIX12 51304084-100 Honeywell Pulse Input Field Termination Assembly may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell MU-TPIX12 51304084-100 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Rectangular and sinusoidal inputs are documented, but sine waves must not be mixed with square-wave or contact signals on the same FTA. Identify all eight connected sensor types before assigning channels. Mechanical terminal compatibility does not establish that the complete waveform combination meets the processor specification.
For mixed signal amplitudes, the manufacturer reduces the maximum frequency to 9 kHz with 50 m FTA cables, 13 kHz at 30 m, 15 kHz at 20 m and 18 kHz at 10 m. The 20 kHz figure applies at 5 m under the stated conditions.
For the documented three-wire connection, transmitter power is 23-25 V DC at open circuit and 21 V at 115 mA load, with a 150 mA maximum short-circuit current. Compare the sensor requirement and field wiring with that specific arrangement before applying system power.
