The Honeywell CC-TPIX11, also cataloged as the CC-TPIX11 Redundant Pulse Input Module, operates as a dedicated hardware component for high-speed pulse processing and frequency metering within Experion Series C DCS platforms. It interfaces directly with field flow meters and turbine generators, converting differential voltage pulse trains into precise digital telemetry over dual channels.

Channel-to-Channel Isolation and Differential Signal Conditioning
Configured with 1000 VDC optical isolation, the Honeywell CC-TPIX11 isolates incoming field pulses from backplane control logic to eliminate ground potential differences across field instrumentation. The internal differential voltage inputs provide dynamic noise filtration, maintaining precise tracking from 0.5 Hz up to 100 KHz on single-channel operations. Built-in cold-junction and isolation signal paths ensure deterministic pulse totalization and custody transfer calculations across the Experion C I/O architecture.
Frequently Asked Questions
Q: How does the optical isolation on the CC-TPIX11 shield system electronics?
A: The internal 1000 VDC optical isolation decouples the high-impedance field input circuit from the backplane, blocking common-mode voltage spikes and high-frequency noise from entering the Series C controller logic.
Q: What frequency constraints apply when operating the CC-TPIX11 in dual-channel mode?
A: In dual-channel mode, the processing threshold is 0 to 10 KHz per channel, whereas single-channel mode supports higher high-speed counting up to 100 KHz with a resolution of 0.1 pulse.
Field Installation Guidelines
Snap the CC-TPIX11 module onto a grounded standard 35 mm DIN rail inside the field enclosure cabinet.
Connect the primary 24 VDC system power lines, verifying supply stability within specified voltage tolerances.
Terminate shielded twisted-pair signal wiring from flow sensors to the designated high-impedance differential input screw terminals.
Earth the cable shield line at the enclosure ground point only, leaving the sensor-side shield floating to prevent ground loops.
Secure all field wiring strain reliefs, ensuring signal cables remain separated from high-voltage power conduits by a minimum of 50 mm.
