Product Name(s): VLD-362W; VLD-362
Product Description: The VLD Series SCUs are programmable display controllers with built in temperature and humidity sensors. Each model is programmable but not expandable and can perform standalone or integrated operation.
Product Application(s): VLD-362: communication with zone HVAC equipment (roof top units, fan coil units, heat pumps, etc.). Used where a combination sensor is required in lieu of separate temperature and humidity sensors. VLD-362W: Same as VLD-362 but with integrated wireless capabilities.
Point Quantity Characteristics
Analog Input (AI): N/A
Digital Input (DI): N/A
Universal Input (AI or DI): See below Controlled voltage, current and resistive modes
Analog Output (AO): N/A
Digital Output (DO): See below Normally open contacts with a maxi switch rating of 24 VAC @ 0.5 A (12 VA).

BO-0, BO-2, and BO-5 are powered from the controller transformer.

BO-1, BO-3, and BO-4 are powered from the controller transformer through removable jumper, allowing these to be powered from a separate power source.
Universal Output (UO): See below Auto-detects for 0-10 VDC or 4-20 mA.

Automatically switches from 0-10VDC to 4-20 mA current mode when it detects a load value of less than 500 Ohms.
