Applications for the HACH SC200 Controller
In water treatment facilities, the LXV404.99.00502 monitors and controls critical parameters like pH, chlorine, or turbidity. Its two 4-20 mA outputs can transmit measurement data to a PLC or SCADA system. The digital sensor input connects directly to HACH digital sensors for fast, accurate readings.
For industrial wastewater applications, the controller’s wide operating temperature range (-20 to 60 °C) ensures reliable performance in harsh conditions. The NEMA 4X/IP66 enclosure protects against dust and water jets, making it suitable for outdoor or washdown areas.
In chemical processing, the LXV404.99.00502 can be configured for PID control to maintain setpoints precisely. The relay output can trigger alarms or actuate valves, providing a complete control solution.
Installation & Setup
Mount the LXV404.99.00502 on a wall, pole, or panel using the included hardware. Ensure the conduit openings (1/2 in NPT) are properly sealed to maintain the IP66 rating. Connect power to the 100-240 V AC or 24 V DC terminals as per the wiring diagram.
For the digital sensor input, use a compatible HACH digital sensor and follow the sensor’s manual for wiring. The two 4-20 mA outputs are isolated current outputs with a maximum load of 550 Ω. Configure the analog output functional mode (linear, logarithmic, bi-linear, or PID) through the controller’s menu.
Set the security levels to protect configuration settings. Two password-protected levels are available to prevent unauthorized changes.
Maintenance & Reliability
Routine inspection of the LXV404.99.00502 ensures long-term reliability. Check the enclosure seals and conduit connections periodically to maintain the NEMA 4X/IP66 rating. Clean the display with a soft, dry cloth as needed.
The controller’s solid-state design minimizes wear, and the isolated analog outputs protect against ground loops. With proper care, the SC200 series delivers years of accurate measurement and control.
Compatibility & Integration
The LXV404.99.00502 works with HACH digital sensors and standard 4-20 mA transmitters. The two analog outputs can connect to any device accepting isolated current signals, such as PLCs, DCS systems, or chart recorders. For additional outputs, an optional expansion module increases the count to five.
The relay output (240 V AC, 5 A) can drive alarms, solenoid valves, or motor starters. The controller also supports dual-channel operation, allowing two measurements to be displayed and controlled simultaneously.
