• Protection features: Reverse polarity protection, short‑circuit protection

• Low‑battery detection threshold: Approximately 2.5 V (monitored by the PLC CPU)

4. Mechanical Specifications

• Dimensions (H × W × D): 130 mm × 17 mm × 125 mm (5.12 in × 0.67 in × 4.92 in)

• Front panel protection: IP20

• Backplane compatibility: All Quantum 140XBP series (10‑slot, 16‑slot)

• Mounting: Standard Quantum rack slot; hot‑swap capable

• Indicators: No onboard LEDs (status reported via CPU or HMI)

• Battery access: Front‑loading slide‑out tray for easy replacement

5. Environmental Ratings (Coated Version)

• Operating temperature: 0 °C to +60 °C, non‑condensing

• Storage temperature: −40 °C to +70 °C

• Humidity: 5 % to 95 % RH, condensing allowed (due to conformal coating)

• Maximum altitude: 2,000 m (6,562 ft) above sea level

• Shock and vibration: Compliant with IEC 60068‑2‑6; coating improves resistance in high‑vibration environments

• Corrosion resistance: Conformal coating protects against dust, moisture, and common industrial gases

6. Compatibility

• CPUs: All Modicon Quantum 140CPU models

• Battery: 3.6 V 1/2 AA lithium (user‑supplied)

• Applications: Chemical processing, food and beverage, marine, outdoor cabinets, and other severe environments

7. Installation and Battery Replacement

Module Installation

1. Align the 140XCP90000C with an empty slot on the Quantum backplane.

2. Push the module firmly until it clicks into place.

3. Tighten the captive screw to 0.8–1.0 N·m.

Battery Insertion

1. Slide open the front battery tray.

2. Insert a 3.6 V lithium battery, observing polarity (positive terminal upward).

3. Close the tray to engage the contacts.

Replacement Interval

• Replace the battery every 5 years, or when the CPU indicates a low‑battery alarm.

• Always replace the battery while the PLC is powered ON to prevent data loss.

8. Maintenance

• Inspection: Every 6 months, check tray closure, contact condition, and coating integrity.

• Cleaning: Wipe the front panel with a dry cloth; do not use solvents (may damage conformal coating).

• Coating care: Avoid scratching or puncturing the PCB coating.

• Disposal: Follow local regulations for lithium battery disposal.

9. Safety Instructions

• Installation and replacement must be performed by qualified personnel.

• Incorrect battery polarity may damage the module or CPU.

• The conformal coating provides environmental protection only; do not modify or remove it.

• Back up the PLC application program before replacing the battery.

10. Warranty

• 12‑month manufacturer warranty (excludes user‑supplied battery; coating defects are covered).

Key Difference: 140XCP90000 vs 140XCP90000C

• 140XCP90000: Standard, non‑coated version for clean, indoor environments.

• 140XCP90000C: Conformal‑coated PCB for enhanced reliability in humid, dusty, or corrosive severe environments。
