Operating from 10-30 V DC (nominal 24 V DC), each output delivers 0.5 A (0.25 A when all 32 outputs active). With 190 mA backplane current at 5 V DC and electronic short circuit\/overload protection, this module provides reliable high-current output control. Weighing approximately 0.45 kg (1.0 lbs), it operates from -13°F to 140°F.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #0056b3; margin-top: 24px;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
