The analog speed control input 0-10 V (pins 4 and 5 of analog input connector) has an
impedance of 500 kOhm. The safe input voltage range is -0.5V to +15V
For the analog output 4-20 mA (pins 2 and 3 of analog I/O connector) the MAX load
resistance should not exceed 500 Ohm.
For equipment safety and to avoid possible excess noise on the speed control input
signal (pins 4, 5 of Analog I/O connector) it is recommended to include an Isolation
Amplifier in the design of the 0-10 VDC remote control external circuitry.
