High speed and high-performance 32-bit ARM microprocessor, with a screen response time of less than 0.2 seconds, can simultaneously detect, record/display, and alarm multiple signals. It is a fully isolated universal input that can input multiple signals without the need for jumper wires. It can be configured through software to switch on and off the power supply. The integrated hardware real-time clock works normally within the range of 85VAC-265VAC, and the clock can accurately operate in the event of power failure. It provides 24VDC isolated power distribution for the transmitter and is equipped with a USB flash drive and cumulative report function. The large capacity FLASH flash memory chip stores historical data and never loses data in case of power failure. The true color TFT high brightness LCD display screen has clear picture and wide viewing angle
