Name: Digital Frequency Meter (Intelligent Type)
Model: AOB194F-9X1
Specification: 30-99.99 Hz (AC30-500V)
Power supply: AC/DC85~264V
Hole: 91x91mm
Usage: It can be used in any environment with high interference, such as frequency converters, soft starters, thyristor voltage regulators, inverters (for photovoltaic projects), etc.
Overview
AOB19 intelligent programmable digital display instrument is a new generation of programmable intelligent voltage and current meter, mainly used for real-time measurement and indication of AC or DC voltage and current in electrical circuits, and remote transmission of measured electricity data through RS485 interface or analog transmission output interface.
Adopting modular design and full SMT production process;
The display range (or transformer multiplier) for voltage and current measurement can be freely set;
One channel analog transmission output function (optional), the output can be programmed to be 0-10mA, 0-20mA, 4-20mA;
One way lower limit alarm output or two-way switch remote control output function (optional), the alarm action delay time can be set arbitrarily within the range of 0-60 seconds;
RS485 communication output function (optional), using standard MODBUS-RTU communication protocol;
It can simultaneously have one analog transmission, one lower limit alarm, and RS485 communication output functions;
Two or four switch input status detection function (optional), combined with RS485 communication to achieve the "remote signaling" and "telemetry" maximum and minimum value viewing function of switch status
