• Digital Input: Model LXV404.99.00502 includes one digital sensor input for seamless connection to Hach digital sensors.
• Analog Outputs: It comes with two 4-20 mA isolated outputs standard, expandable to five with an optional module.
• Communication Ready: Supports various protocols for easy system integration (protocol modules sold separately).
• Direct Replacement: This SC200 replaces older SC100 and GLI53 controllers with advanced features and backward compatibility.

Key Features & Benefits

• Intuitive Interface: A large graphic dot matrix LCD with LED backlighting provides clear readings. Step-by-step menus reduce operator errors.
• Flexible Output Configuration: The two 4-20 mA outputs transmit primary or secondary measurements. Users can select linear, logarithmic, bi-linear, or PID functional modes.
• Robust Environmental Tolerance: With an operating range of -20 to 60 °C and 0 to 95% RH (non-condensing), it performs reliably in harsh conditions.
• Durable Enclosure: The NEMA 4X/IP66 rated housing protects against dust, wash-downs, and corrosion.
• Multiple Mounting Options: Supports wall, pole, and panel mounting configurations for versatile installation.

FAQ

• Q: How many sensors can I connect to the LXV404.99.00502?
  A: This model features one digital sensor input, designed for a single Hach digital sensor.
• Q: Can I expand the number of analog outputs?
  A: Yes. The SC200 supports an optional expansion module to increase from two to five isolated 4-20 mA outputs.
• Q: What functional modes are available for the analog outputs?
  A: Users can select Linear, Logarithmic, Bi-linear, or PID modes for the 4-20 mA outputs.
• Q: Is this controller suitable for outdoor installation?
  A: Yes. The Hach SC200 has an IP66/NEMA 4X rating, making it suitable for outdoor or wash-down environments.
• Q: Does it come with communication protocols like MODBUS?
  A: Communication modules (MODBUS, Profibus, HART) are available as optional accessories and are sold separately.
