This is the most frequent use case. The "VLC" prefix often stands for or Voltage Laser Controller , and "1600" typically denotes optical output power in milliwatts (mW) or the peak wavelength (e.g., 1600 nm). In many datasheets, the VLC 1600 is a 1650nm to 1680nm Fabry-Perot laser diode designed for fiber optic sensing or medical applications.
The 16 universal inputs on the VLC-1600 line can be field-configured depending on the sensor type. Physical wiring termination blocks consist of removable header-type screw terminals engineered for . Sensor Support Profiles vlc 1600 datasheet
The VLC 1600 datasheet will explicitly state the front facet material. For this power level, expect an or a nitride-passivated facet to withstand high power density.
The is more than a specification sheet—it is a contract between the component and the engineer. It tells you the maximum current you can push, the temperature it can survive, and the light it will emit. Whether you are designing a free-space optical link, a fiber laser, or a LIDAR system, studying the datasheet carefully is non-negotiable. Laser Anode ──> Vcc (>3V) │ [Current Sense
Monitoring complex processes to identify inefficiencies or failures.
Acts as a specialized input node in large-scale HVAC systems. 5. Conclusion The 16 universal inputs on the VLC-1600 line
: Supports 10k Type II thermistors as well as legacy 3k (Ibex) temperature elements.
It is crucial to note that the VLC-1600 is designed primarily as an and, according to official Honeywell documentation, "has no control outputs". The VLC-1600 offers 16 universal inputs that are jumper-selectable to accept a variety of signal types. The older VLC-1600 model features 16 10-bit universal inputs . Input 0 is specifically designed for a BACtalk Microset sensor, while inputs 1-15 can be configured for thermistor, dry contact, 0-5 VDC, 0-10 VDC, or 4-20 mA signals. Some inputs also support pulse-type signals.
