The UTP28CH6BU series active and reliable dual-channel HART multiplexers can be used in a wide range of applications, such as chemical, petrochemical, pharmaceutical, power and refineries applications. They are designed for transmitting and receiving HART communications in all two-wire systems. UTP28CH6BU is an ideal choice for complex multi-point HART networks with two-wire systems, providing dual-channel HART multiplexing capability.UTP28CH6BU is basically composed of two parts, a two-channel multiplexer and a receiver. The multiplexer has two inputs and one output. Both inputs on the UTP28CH6BU can be used to receive data from two different HART devices. The output is AC coupled and can be used to transmit HART data to another HART device. The UL approved receiver module is designed to properly receive the transmitted signal, and the received signal is then processed by the multiplexer to produce a filtered output. This output can be used to monitor and control any remote HART field device with its respective output.The working principle of UTP28CH6BU is based on the pulse-width modulation (PWM) technique. Each of the two multiplexers contains eight switches which enable high PWM resolution. In the multiplexer, signals from both inputs are first filtered by a low-pass filter then input into an oscillator. The oscillator generates a square pulse which modulates the signal so that the PWM pulses can be detected accurately by the receiver. The received signals are then monitored and filtered before delivering the output to the application being monitored.The UTP28CH6BU series allows the user to monitor and control multiple HART field devices from a single control station. The input on the multiplexer can be used to gather data from multiple HART field devices while the output on the multiplexer can be used to monitor and control the selected device. The output on the receiver is connected to the application being monitored. This allows the user to send and receive data in both directions with the field device and the control station.The UTP28CH6BU provides high accuracy and reliability due to its two-stage filtering and modulation technique. This technique helps to ensure that the data transmitted through the two-wire system is of the highest quality and accuracy. The use of the UTP28CH6BU series is not limited to HART applications, and it can also be used in a variety of industrial applications where multiple IO devices need to be monitored and controlled.The UTP28CH6BU series is a highly reliable and versatile solution for multiplexing up to two HART field devices in a two-wire system. It provides a versatile means of monitoring and controlling multiple HART field devices from a single location. The series provides improved accuracy and reliability due to its two-stage filtering and modulation. The UTP28CH6BU series is also easy to install and configure, making it an ideal choice for complex monitoring and control applications involving multiple HART field devices.
