Honeywell MU-TPIX12 Pulse Input Termination Board

The Honeywell MU-TPIX12 (Part No. 51304084-100) is a pulse input Field Termination Assembly (FTA) engineered for industrial distributed control architectures. It manages up to 8 channels of pulse or contact inputs from self-powered 2-wire or PM/APM/HPM-powered 3-wire sensors, providing signal routing and conditioning for rectangular or sine wave pulse signals.

Signal Processing and Frequency Response

The termination board accommodates input frequencies up to 20 kHz for both 50% duty cycle square waves and sine waves, supported by a minimum input impedance of 10 kΩ. It defines distinct pulse level thresholds, accepting low states from -0.5 V to +1.9 V and high states from +3.5 V to +24 V, with built-in hysteresis to prevent false triggering between 1.9 V and 3.5 V.

Pulse Width and Filtering Configuration

Configurable dwell times accommodate varying frequency requirements based on input filtering. It supports minimum on/off dwell times of 25 µs at 20 kHz with the IOP filter jumper in the storage position, 50 µs at 10 kHz in the high position, and 500 µs at 1 kHz in the low position.
