5.3 Typical Application Cases
Case 1: Temperature Control of Chemical Reactor
Application: Convert millivolt thermocouple signals to standard 4-20mA signals; set dual thresholds for high temperature alarm (85°C) and over-temperature shutdown (95°C)
Configuration: CC-U/STDR + Type K thermocouple adapter, 24VDC power supply
Advantages: Triple isolation eliminates ground loop interference; dual relay outputs realize hierarchical control and improve operational safety
Case 2: Pressure Monitoring for Building HVAC System

- Selection Tips & Quick Reference Rules
Selection Rhythm
The CC series includes U (Universal) and E (Economy);
STD for standard signals, R for relay output, check power supply carefully;
24/48V for low voltage, 110/240V for high voltage;
Triple isolation against interference, 10-millisecond response;
This series is discontinued, plan upgrade in advance.
Quick Reference Rules
- Model Identification: CC-U/STDR = Universal type + Standard signal + Relay output
- Order Number Distinction: 1SVR040010R0000 = 24-48V power supply; 1SVR040011R2500 = 110-240V power supply
- Core Advantages: Triple isolation, independently adjustable dual relays, 7 selectable input signals
- Status Reminder: All legacy CC-U series products are discontinued. Select ABB TTH300 series or third-party alternatives for new projects.
- Troubleshooting & Maintenance
| Fault Phenomenon | Possible Causes | Solutions |
| No Output Signal | 1. Power supply disconnected or abnormal voltage | 1. Check 24-48VDC/24VAC power supply |
| 2. Incorrect DIP switch settings | 2. Reconfigure DIP switches (input type, output mode) | |
| 3. Input signal out of range | 3. Measure input signal and ensure it is within 0-20mA/0-10V range | |
| Relay Fails to Actuate | 1. Threshold set too high/low | 1. Readjust threshold potentiometer |
| 2. Excessively large hysteresis value | 2. Reduce hysteresis value | |
| 3. Damaged relay contacts | 3. Measure contact resistance; replace unit if contacts are damaged | |
| Fluctuating Output Signal | 1. Interference on input signal | 1. Check shield wiring and add filter |
| 2. Excessive power supply ripple | 2. Connect a 100渭F capacitor in parallel to power terminals | |
| 3. Poor contact of potentiometer | 3. Clean or replace the potentiometer | |
| Loss of Isolation | 1. Wrong wiring across isolation zones | 1. Rewire strictly to separate input, output and power circuits |
| 2. Equipment aging | 2. Replace with new device (select replacement model due to discontinuation) |
