1. Power ( 3 Ph.electric motor, full load current 4.9A ) : Multistrand copper cable 2.5 Sq.mm (Rating 1100V and 25A when laid inside a hose) 2. Digital I/O ( max solenoid current 1.28A) : Multistrand copper cable 1.0 Sq.mm x 2 core for each solenoid ( Rating :110V / 7A) 3. Analog Signal ( 4-20mA from pressure and temperature sensor) : 0.25 Sq.mm x 2 core Ragu, Without the motor spec, I'd be a bit leery of 20m cable voltage drops on startup. |
