Select a location that allows for easy access to the US5182’s removable screw terminal blocks and connection ports. Using the four screw holes in the base of the device, mount the US5182 directly to a flat vertical or horizontal surface in an enclosure that is located away from excessive dust, heat, moisture, or direct sunlight.
Installation US5182 Wiring Connections Make wiring connections using a small screwdriver. The terminal blocks are removable, which may simplify the installation. US5182 +24VAC (R) Power AIR HANDLING UNIT CONTROLLER POWER -24VAC (C) Digital Outputs Digital Inputs +P (24VDC) Analog +P (24VDC)
The US5182 is powered from a 24 VAC +20/–5% transformer. If wiring for communications, dedicated power must be used to power the device, rather than power from the HVAC equipment. Several TCS controllers may be powered from the same transformer, provided that the transformer has enough power.
Installation Analog Inputs Connect 4 – 20mA analog inputs to the US5182 using 18AWG two-wire twisted, stranded, shielded wire. The inputs can be two-wire or self-powered. +P (24VDC) +P (24VDC) US5182 +24VAC (R) AIR HANDLING UNIT CONTROLLER POWER -24VAC (C)
Installation Temperature Inputs Connect PtRTD 1000Ω temperature inputs using 18AWG two-wire twisted, stranded, shielded wire, maximum 250 ft. length. US5182 +24VAC (R) AIR HANDLING UNIT CONTROLLER POWER -24VAC (C) TEMPERATURE (RTD) INPUTS DISCH OUTDOOR MIXED SPACE RETURN DISCH +P (24VDC)
Connect 4 – 20mA, analog output devices using 18 – 22AWG two-wire twisted, stranded, shielded, or unshielded wire. Connected actuators, motors, or drives must be powered separately from the US5182. If you desire a 2 – 10VDC output, use an included 500Ω resistor.
Earlier versions of Insight will not allow you to configure the US5182. Connect a USB-A to USB-C cable (NOT a mini-USB or micro-USB cable) between the US5182 and the PC. US5182 +24VAC (R)
