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 -0.5 V to +15 V.
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.
