Basic Application Default I/O Configuration
GND terminals 3, 7 and 13 are internally connected.
For the STANDARD Application, input signals at DIN1 and DIN2 are
programmed as a pair using parameter 2.1.
Connect CMA/CMB inputs to either logic high or logic low depending
upon your application. Refer to the
SVX9000 User Manual
and
SVReady Application Manual
for additional information.
Maximum Switching Voltage: 300V DC, 250V AC
Maximum Switching Load: 8A/24V DC; 0.4A/250V DC; 2 kVA/250V AC
Maximum Continuous Load: 2A rms
