Product performance description Portable toolkits Various connection accessories Fast reading Supports all HART instruments USB and RS232 Interface optional Industrial upgrade Welcome to contact us. Microcyber

In the instruments industry, the traditional 4 20 mA analog transmitters are upgrading to the fieldbus with digital communication. HART fieldbus communication has digital communication capability with compatible analog signal. HART MODEM is a necessary and convenient tool for the analog products upgrading and signal exchanging in the control plant. We provide two kinds of HART modem. HART-RS232 is the converter for HART signal to RS-232 signal. HART-USB is the converter for HART signal to PC virtual series port. Product characteristic: According to the HART physical layer specification Isolated transformer prevents the influence of earthing. Voltage signal modulator/demodulator Low power consumption designation Powered by series port or USB port Interface Type: DB9 female mount Ambient Temperature: 0 ~ 50 °C Compressive Strength :500 V AC HART bus and serial port (UART,USB) Receiving Impedance : â?¥5 K Ω, end-to-end Output Signal VPP: 600 mV â?¥ VPP â?¥ 400 mV, 500 Ω load resistance Receiving Sensitivity: 120 mV, 500 Ω test resistance HART-RS232 is the protocol converter between HART device and configurator on PC. The figure above is a sample basic case. To connect multiple HART device, please connect the other devices parallel with the Transmiter. Please note that the power should support multiple devices and the terminator should be set in the middle of the power and parallel point. HART-RS232 is a HART MODEM with voltage modulator/demodulator. To communicate with a HART device, please connect the clincher of HART port of HART-RS232 to the two terminals of the network adaptor resistance or the power of HART device. To communicate with a PC, please connect the other port of HART-RS232 to the series port of PC. The USB driver installation program should be run for HART-USB. The driver provides a virtual series ports for HART configurator software. The indication light shows the state of modem. Green LED indicates the power is working well and the modem is sending data. Red LED indicates the modem is receiving data
