The Allen Bradley 1771-OBN digital DC Output Module is designed for Zone 2 environments with pollution degree 2, accessible only via appliance to protect its sensitive components from electrostatic discharge up to 4 kV on contact and 8 kV through air. It features 32 outputs divided into four groups of eight, each capable of delivering between 10 and 30 V DC at 0.5 A per output, with an impressive isolation voltage of 1500 V AC RMS tested to withstand 500 V for 60 seconds. With operational efficiency highlighted by a maximum power dissipation of 13.7 W and a thermal dissipation of 46.7 BTU/hour, it operates reliably between 32 and 140°F (0 and 60°C) with a relative humidity range up to 95% non-condensing, safeguarded by four 4.0 A, 250 V fuses for optimal protection.
