42 – 53Vdc input; 12Vdc Output; 25A output current
Feature Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions. See Feature Descriptions for additional information.
Parameter
Remote On/Off Signal Interface
(V_IN=V_{IN, min} to V_{IN, max} ; open collector or equivalent,
Signal referenced to V_IN- terminal)
Negative Logic: device code suffix “1”
Logic Low = module On, Logic High = module Off
Positive Logic: No device code suffix required
Logic Low = module Off, Logic High = module On
Logic Low Specification
Remote On/Off Current – Logic Low
On/Off Voltage:
Logic Low
Logic High – (Typ = Open Collector)
Logic High maximum allowable leakage current
