CC-PUIO31 — Honeywell Series C 32-Channel Universal Process I/O Module
CC-PUIO31 is the electronics module — the IOP — for Honeywell’s later Series C universal process I/O. It is not a termination assembly. Honeywell documents a dedicated IOTA pair: CC-TUIO31 (non-redundant, 9 inch) and CC-TUIO41 (redundant, 12 inch). That is a different mechanical family from CC-TUIO11, which serves CC-PUIO01. HKXY Instruments is a China industrial automation trader with 15 years of export experience, not the OEM.

Per-channel configuration
From Honeywell EP03-490-520 section 5.20, each channel may be configured as analog input, analog output, digital input, DISOE (sequence of events: 1 ms resolution SOE, 20 ms PV scan), digital output, or pulse input. Pulse input is allowed on any four channels. Open-wire detection, per-channel FAILOPT for digital/analog outputs, HART 7 on analog I/O, and a HART modem per channel are documented. Fast (priority) I/O module scan and electronic short-circuit protection are listed. Module ambient: −40 to +70°C.
Selected analog, pulse, and digital ratings
Always re-check channel-count vs temperature derating in the Series C User’s Guide. Honeywell notes that mixed AO/HART configurations can require a usage calculation.
| Function | Documented specification |
|---|---|
| Analog input | 2-, 3-, or 4-wire current; up to 32 channels; 0–20 mA or 4–20 mA; 16-bit A/D; 250 Ω input impedance; 10 ms scan; hardware accuracy 0.1% FS at 23.5°C ±2°C, 0.175% FS from 0 to +70°C, 0.25% FS from −40 to +70°C; short-circuit current limit 25 mA |
| Pulse input | Any 4 channels; 0–15 kHz; minimum pulse width 25 µs |
| Analog output with HART | 4–20 mA; up to 32 channels; 12-bit resolution; calibrated accuracy < 0.35% FS at 25°C including linearity; settable 0 mA and 2.9–21.1 mA; max load 825 Ω at 20 mA; compliant voltage 16.5 VDC at 20 mA; response 80 ms in HART mode, 0.25 ms in non-HART mode; 0 ms switchover gap |
| Digital output | Solid-state source, short-circuit protected; 1 mA min to 0.5 A max per channel; 9 A max per module (configuration and temperature dependent); typical on-state 24 V at 0.5 A |
| Digital input SOE | 1 ms resolution on any/all channels, with or without open-wire detect (field resistor rules in the User’s Guide) |
RFQ checklist
- Photograph CC-PUIO31 and the IOTA (CC-TUIO31 or CC-TUIO41).
- Export the channel map, including which four channels (if any) are pulse and which analog points use HART.
- Note cabinet ambient — Honeywell requires a usage vs temperature calculation for dense AO/HART or DO loading.
- Confirm Experion release and that you are not trying to replace a CC-PUIO01 / CC-TUIO11 assembly with this generation.
- Quantity and destination. Stock, price, and lead time are [TO CONFIRM].

FAQ
Is CC-PUIO31 interchangeable with CC-PUIO01?
No. They use different IOTA sizes and have different pulse-channel rules. Treat them as separate generations.
Which IOTA do I order?
CC-TUIO31 for non-redundant 9-inch mounting, or CC-TUIO41 for redundant 12-inch mounting.
How many pulse inputs are allowed?
Any four of the 32 channels, at 0–15 kHz with a 25 µs minimum pulse width.
Does every analog channel have HART?
Honeywell documents HART 7 support and a HART modem per channel for analog I/O. Enabling HART on an energized AO can disturb the output for no more than 65 ms while the channel reloads — plan commissioning accordingly.
Can you show live inventory here?
No. Availability is [TO CONFIRM] after verification.
