Dual H-bridge, 3 state, pulse width modulated (PWM) switching at 25
kHz. 0.1 - 1.2 amps/phase output current, software selectable. 48 watts
maximum output power. Automatic idle current reduction (software
programmable) reduces current to motor when idle. Minimum motor
inductance is 0.8 mH.
Accepts 12 - 42 VDC power supply. 1.2 amps typical max. load.
5 - 24 VDC, optically isolated. 2200 ohms internal resistance. Can be
configured for sinking (NPN) or sourcing (PNP) signals.
Analog Input - not currently supported by Si Programmer, may be read
in SCL mode using “RA or “IA” commands
Optically isolated. 5-24 VDC, 100 mA max.
