Technical Specifications

Key Features & Benefits

1. Modular plug‑and‑play input‑card design: Field‑replaceable analytical input cards; this variant is configured for pH‑ORP single‑channel operation, can later retrofit conductivity or dissolved‑oxygen cards on‑site without sending unit back to factory.
2. Integrated PID closed‑loop control: Built‑in PID algorithm directly drives dosing valves / chemical metering pumps for pH neutralization treatment, reduces requirement for external PLC control loops.
3. Rich local human‑machine interface: Backlit graphic LCD, multi‑language menu, local calibration wizard, on‑board event log stores calibration records, alarm history and diagnostic faults.
4. Flexible alarm relay logic: Two configurable alarm relays support high‑pH / low‑pH, sensor fault, temperature alarm; relay dry‑contacts connect to local annunciator or DCS interlock.
5. Harsh‑environment robust construction: NEMA4X front panel, Class I Div2 hazardous‑area certification, suitable for chemical plant, water‑treatment cabinet field installation.
6. Traceable calibration documentation: Factory calibration conformance certificate included (‑C0 option), satisfies pharmaceutical, power‑plant QA audit requirements.
7. Local IR service interface: Wireless infrared port supports handheld tool for parameter upload/download without opening cabinet wiring terminals.

Application Fields

‑ Power‑generation plants: Boiler feed‑water, condensate water, pure‑water system pH & ORP monitoring and chemical dosing control. ‑ Waste‑water treatment plant: pH neutralization process control for influent‑effluent discharge. ‑ Chemical & petrochemical industry: Liquid‑phase pH/ORP continuous analysis for reaction vessels. ‑ Pharmaceutical & food‑beverage: Process water quality monitoring with calibration‑audit requirement. ‑ Pulp‑and‑paper mill: Bleaching‑process ORP monitoring. ‑ Spare‑part replacement for existing UDA2182 installed base with single‑channel pH‑ORP measurement demand.

Installation Guidance

1. Mechanical panel‑mount installation: Cut standard 1/4‑DIN panel cut‑out 138×138 mm; insert UDA2182 unit from front of panel; fasten rear mounting clamps securely; keep sufficient rear‑side ventilation clearance for heat dissipation. This part number 00 suffix: no pipe‑wall mounting accessories supplied.
2. Sensor field wiring: Connect pH/ORP glass electrode and RTD temperature compensation sensor to rear Ch‑1 input terminals; strictly follow Honeywell sensor wiring diagram; use shielded low‑noise cable for pH probe signal wiring, separate from high‑power AC power cables to avoid interference.
3. Power wiring: Connect 90‑264 VAC power supply to rear power terminals; install external fuse per electrical safety requirement.
4. Output‑relay & analog‑output wiring: Wire 4‑20 mA analog outputs to DCS / recorder; wire alarm‑relay dry‑contacts to external alarm interlock circuit, respect relay contact load rating.
5. Commissioning & configuration: Power‑on unit; navigate front‑panel menu, define sensor type, set PID control parameters, configure alarm threshold; perform two‑point buffer‑solution pH calibration. Review event‑log after calibration completion.

Important Notes ‑ Channel‑2 slot on this unit is empty (NN2); if second‑parameter measurement is required, purchase and install corresponding plug‑in input card locally. ‑ This specific part number has NO Ethernet / Modbus communication card fitted; only IR local service interface available. ‑ Sensor cable shall not be bundled together with motor power cables to prevent high‑frequency noise drifting pH readings.

Maintenance Recommendations

1. Routine inspection: Check front‑panel display status, inspect rear terminals for loose wiring and dust accumulation.
2. Periodic calibration: Perform pH two‑point buffer calibration on site following plant maintenance schedule. Download event log via IR handheld tool to review calibration history and sensor‑fault records.
3. Replace pH glass electrode according to process medium fouling condition.
4. For input‑card upgrade: Power‑off analyzer before swapping plug‑in input modules.
5. Refer to Honeywell official manual document 51‑52‑16U‑85 for complete installation constraints, calibration procedure and troubleshooting guidance.
