Remote On/Off Signal Interface
(VIN=VIN, min to VIN, max , Signal referenced to VIN- terminal)
Negative Logic: device code suffix “1”
Logic LO = module On, Logic HI = module Off
Positive Logic: No device code suffix required
Logic LO = module Off, Logic HI = module On
Logic LO Specification
On/Off Thresholds:
Remote On/Off Current – Logic LO (Vin =100V)
Logic LO Voltage
Logic HI Voltage – (Typ = Open Collector)
