Explosion-proof instrument

The basic function
High - speed high performance ARM processor, 32-bit precision floating-point operation.
Industrial grade high reliable isolation power, 24V DC/220V AC wide input, multiple protection.
The change table does not need to be re-calibrated, only the parameters of the original instrument can be used.
It is completely isolated from 0-5v / 0-10v / 4-20ma analog output, and can be calibrated in multi-mode.
Total isolation RS485 and RS232 double serial port high-speed output; Standard communication protocol (modbus-rtu)
External large screen current loop output interface.
The isolation switch is 3 out of 3 control.
The sensor signal acquisition and conversion circuit adds patent technology, which can be self-diagnosis and self-protection, and it is more comfortable to use.
