    Wiring Diagram:

    The Javelin D is an easy-to-use, 1/8 DIN digital voltmeter that accepts a DC voltage input up to 300 VDC. It features a built-in 4-20 mA isolated transmitter, RS-485 serial communication capability, and a NEMA 4X/IP65 rated front. The four front panel buttons provide quick and simple access to programming and operation functions. There are no jumpers, and no need to ever open the case. After completing setup of one meter, additional meters can be cloned using the time-saving copy function. The optional Form C relays can be used for alarm indication or process control applications. The Modbus® RTU serial communication upgrade enables the Javelin D Digital Voltmeter to operate as a Modbus® slave in RS-485 multi-point data acquisition systems.
