Product Overview

The Watlow 997D-11CC-JURG is a legendary Dual Channel Temperature/Process Controller from the 997 Series. Although now considered a "Legacy" product by the manufacturer, it remains the heartbeat of many semiconductor furnaces, environmental chambers, and heat-treat ovens that have been running for decades.
At Xiongba Automation, we specialize in the "Hard-to-Find" Legacy Market. We know that upgrading to a modern controller (like the F4T) requires expensive rewiring and panel modification. The most cost-effective solution is a direct, verified replacement. We stock and source these discontinued units to keep your vintage production lines running without a retrofit headache.

Technical Configuration Breakdown (The DNA):

1. Series: 997D (Auto-tuning, Microprocessor-based).
2. Configuration: Dual Channel (Control two separate loops or heat/cool logic).
3. Suffix "11CC-JURG": This specific string defines the Input Type (e.g., Thermocouple/RTD), Output Hardware (Relay vs. Solid State), and Power Supply.

Warning: You cannot swap this with a "997D-22..." or other variants. The internal output cards are physically different.

Verification & Risk Control

Since the 997D-11CC-JURG is out of production, most units on the market are used or refurbished. Xiongba Automation enforces a strict "Revival Protocol" to ensure quality:
1. Display Brightness Check: These units use older LED/VFD displays that dim over 10+ years of service. We power up every unit and reject any with "Ghosting" or Dim Segments. You need to read the numbers clearly from across the room.
2. Tactile Button Audit: The front membrane keys often lose their "click" or become unresponsive. We manually test the Up/Down/Set keys to ensure they register every press.
3. Output Logic Test: We don't just power it on; we simulate a signal to ensure the Output Relays (Click) or SSR Drivers (Voltage) actually trigger when the setpoint is raised.
4. 12-Month Hardware Warranty: Even for legacy goods, we offer a 1-year warranty. Note: This covers electronic failure. It does not cover damage from connecting 110V to a low-voltage logic output.

Project Lifecycle Support

We support maintenance managers dealing with "End-of-Life" (EOL) equipment:
1. Maintenance Spares (Stocking):
Running a semiconductor fab with 20-year-old furnaces? We recommend keeping at least one 997D-11CC-JURG on the shelf. Availability of this specific part number is shrinking globally.
2. Emergency Replacement (Machine Down):
Instant Verification: If your line is stopped, ask for a Live Video Test. We will power up the specific unit allocated to you and walk through the menu to prove it works.
Fast Shipping: We treat legacy replacements as priority shipments.

RFQ Checklist

5. Fault on old unit: Display / Output / Power (Helps us advise)

FAQ

Q: Is the 997D-11CC-JURG brand new from the Watlow factory?
A: This series is Obsolete (Discontinued). "Factory New" units are extremely rare. Xiongba Automation primarily supplies Verified Surplus or Refurbished units. We are transparent about the condition (e.g., cosmetic scratches) before you pay.

Q: Can I replace this with a modern Watlow PM or F4T controller?

A: Yes, but it is not plug-and-play. The wiring terminals, panel cutout size, and programming logic are different. Unless you have an electrical engineer to redesign the panel, we recommend replacing "Like-for-Like" with the 997D.

Q: How do I unlock the menu? It asks for a password.

A: We ship units reset to factory defaults where possible. However, if your old unit had a custom lock code, you need to consult your original machine manual. We supply the hardware, not the process engineering password.
