Three panel formats are available: CP‑04(96×96 cutout 92×92 mm), CP‑08(horizontal 96×48), CP‑H8(vertical 48×96). Equipped with 3.5‑inch IPS TFT color LCD and dust‑proof tactile keys, front‑panel IP66 rating. Full galvanic isolation among input, output and power supply delivers excellent noise immunity for industrial cabinet environments.
Key Features
✅ Specialized Oxygen‑probe Measurement & Health Diagnosis Dedicated measuring circuit for zirconia oxygen probe; probe internal resistance detection and soot alarm. Supports auto‑clean & manual‑clean function with safety‑temperature interlock to extend probe service life and simplify field wiring.
✅ AI‑optimized Online Case‑depth Calculation with Alloy Correction Alloy coefficients (Si, Cr, Ni, Mn, Mo) are configurable. Accept real‑time CO/H₂ analyzer input or fixed‑gas‑concentration calculation. Real‑time case‑depth display and data recording for precise carburizing evaluation.
✅ Powerful Multi‑segment Program Profiles Stores up to 50 recipes, max.16 segments per recipe. Supports deviation‑wait, program cycle, power‑off resume, ramp‑back and reset. Each segment assigns independent DIO timing outputs for enriching/carrier gas solenoid‑valve sequential control for complete carburizing‑diffusion cycles.
✅ 5‑Group Switchable PID Control Five sets of independent PID parameters can be auto‑switched based on PV, SV or program segments. Auto‑tune AT, output limit and over‑shoot suppression reduce oscillation for stable carbon potential regulation across heating, soaking and cooling phases.
✅ Flexible I/O Configuration Oxygen‑probe 0‑2V dedicated input; second channel supports 43 universal sensor signal types; third channel configurable as CO/H₂ analyzer input or retransmission output. 16‑point user‑defined linearization for non‑standard sensors. Multiple analog/relay/SSR outputs; up to 9 alarm & DIO channels (2‑relay dry‑contact +7 open‑collector DIO). DIO pins freely configured as DI input or DO output for external trigger, program reset, segment skip, manual probe cleaning. Interlock logic for carrier‑gas / enriching‑gas and safety‑temperature cut‑off.
✅ Dual‑port Industrial Communication Dual RS485 Modbus‑RTU as standard; optional Modbus‑TCP Ethernet. Supports parameter modification and real‑time data upload for HMI, PLC, SCADA and MES system integration.
✅ Industrial‑grade Hardware Reliability 1800V AC isolation between I/O and power. Wide‑range power supply AC86‑260V / DC24V. Domestic real‑time multi‑task OS with strong noise immunity, IP66 front‑panel protection. OEM & ODM customization available.
