Overview

HD-484ZL Intelligent pressure / differential pressure transmitter controller is a fully digital measurement and control product that integrates pressure/differential pressure measurement, display, contact control and transmission output, and has an RS485 digital interface. It can be directly installed at the on-site pressure/differential pressure measurement point or on the test bench control panel. It can use buttons to set various parameters such as zero point value, full scale value, contact pressure/differential pressure value, etc. on-site, and can also use RS485 bus function to realize network, digital signal transmission and remote setting and adjustment of transmitter parameters. It is widely used in the automatic control field of hydropower, metallurgy and chemical industries to measure and control the pressure/differential pressure of fluid media.

     Features

     Φ150mm design, ultra-high brightness LED full four-digit pressure display. AC and DC power supply options.

    RS485 interface, standard Modbus RTU protocol, convenient for networking and data transmission.

    It can realize remote setting of product zero point, full scale display value, control contact value and other parameters

    Press the button to set the parameters of the transmitter controller on site, reset to zero, and manage passwords by category

    Can output standard analog signal 4mA ~ 20mA DC or 0V ~ 10V DC

    Up to 5 control contacts, contact value and contact status can be set arbitrarily

    The control contact can set the hysteresis value to eliminate the contact jitter phenomenon and ensure reliable control
