WATLOW ANAFaZe 997D-11CC-JURG – Multi-loop Temperature Controller for Demanding Thermal Processes
The WATLOW ANAFaZe 997D-11CC-JURG is part of Watlow’s proven Anafaze multi-loop PID platform, designed to stabilize multiple heat zones with tight control and fast recovery. From my experience, this family is a go-to when you need stable, repeatable temperature across several zones without tying up a PLC for core PID duty. You might notice that it drops in neatly where older Anafaze 97-series units lived, which makes replacements and upgrades straightforward in many cases.

- Flexible I/O configuration – Typically supports TC/RTD inputs with a mix of SSR drive, relay, or analog outputs depending on option code.
- Fast autotune and stable control – Shortens commissioning time and improves thermal stability during load changes.
- RS‑485 connectivity – Modbus RTU style communication for SCADA/MES integration and parameter backups.
- Profile ramp/soak capability – Enables heat-up, hold, and cooldown recipes for ovens, chambers, and process tools.
- Noise immunity – Designed for industrial panels with good EMC practice; typically reliable near high-current heaters.
- Service-friendly – Front-panel access and status indicators simplify troubleshooting in the field.
Technical Specifications
The following reflects typical specifications for Watlow Anafaze 97‑series multi-loop controllers; exact details may vary by the -11CC-JURG option build.
| Brand / Model | Watlow Anafaze 997D-11CC-JURG |
| HS Code | 9032.89.00 – Automatic regulating or controlling instruments |
| Power Requirements | 100–240 VAC, 50/60 Hz, approx. 15 VA |
| Dimensions & Weight | 1/4 DIN front (96 × 96 mm), panel cutout ~92 × 92 mm; depth ~150 mm; ~0.7 kg |
| Operating Temperature | 0 to 50 °C (storage −20 to 70 °C) |
| Signal Inputs | Thermocouple (e.g., J/K/T/E) and/or RTD Pt100; optional analog (4–20 mA / 0–10 V) per option code |
| Outputs | SSR drive (typically 12 VDC), Form C relay, and/or 4–20 mA control outputs depending on configuration |
| Communication Interfaces | RS‑485 (Modbus RTU style) for supervisory control and data logging |
| Installation Method | Panel mount, 1/4 DIN; rear screw terminals; shielded sensor wiring recommended |
Application Fields
This controller fits well in industrial ovens, heat-treat lines, thermal chambers, plastics extrusion and die zone control, food processing ovens, textiles heat-setting, and semiconductor sub-systems where several heaters need coordinated ramp/soak and stable hold. One thing I appreciate is how it handles mixed zones—band heaters, cartridge heaters, and IR panels—without fighting overshoot in adjacent loops.
“We swapped a legacy Anafaze unit with this 997D variant and reused the panel cutout and most wiring—downtime was under two hours.” – Maintenance Supervisor, batch oven retrofit
Advantages & Value
- Reduced panel footprint – Multi-loop control in one unit often replaces multiple single-loop controllers.
- Compatibility – Works well with Watlow power controllers (e.g., DIN‑A‑MITE) and standard industrial sensors.
- Lifecycle cost savings – Fewer devices to maintain, and parameter backups over RS‑485 help speed service.
- Reliable sourcing – Lead times that typically stay inside a month, with in‑stock options shipping in a week.
- Support – Parameter guidance and start-up assistance on request to shorten commissioning time.
Installation & Maintenance
- Panel/cabinet – 1/4 DIN cutout; allow rear clearance and ventilation. Keep ambient below 50 °C.
- Wiring practice – Separate high-current heater wiring from low-level sensor leads; use shielded TC/RTD cable and earth the shield at one end.
- Protection – Fused AC supply, proper earth ground, and SSR heat-sinking sized to load.
- Tuning – Run autotune after installation or major process changes; verify ramp/soak recipes at reduced setpoints first.
- Routine care – Annual calibration check, clean ventilation slots, verify alarm setpoints, and back up parameters via RS‑485.
Quality & Certifications
- Typically compliant with CE and UL/cUL for industrial control equipment; RoHS status generally supported for current builds.
- Manufacturer warranty is commonly 1 year; our coverage: 365 days.
- Traceable documentation and test reports available upon request.
Recommended Supporting Components
- Watlow DIN-A-MITE A/B/C – Solid state power controllers for single/three-phase heater loads; ideal with SSR drive outputs.
- Watlow EZ-ZONE RM I/O modules – When you need expanded I/O or integrated safety limits alongside the Anafaze control strategy.
- Watlow Type K and Type J thermocouples – Matched sensors with industrial connectors for quick replacement in the field.
- Panel accessories – DIN rail terminal blocks, shielded cable, and proper fusing to meet panel best practices.
It typically denotes a specific mix of inputs/outputs and firmware options for the 997D family. If you share your existing unit’s label photo or I/O needs (sensor type, number of loops, output types), we’ll match the exact configuration to ensure a drop‑in replacement.
