The Allen-Bradley 1719-PSDC Ex I/O DC Power Supply delivers 24 VDC at up to 45 W to power 1719 Ex I/O modules in hazardous locations. This intrinsically safe DC power module is rated Zone 2/Class I, Division 2 and has dimensions of 32 x 100 x 103 mm with an approximate mass of 220 g. Operating temperature ranges from -4 to 140°F (-20 to 60°C), and the unit dissipates about 15% of its rated power as heat. For reliability in critical applications, up to three PSDC supplies can be used in an N+1 configuration to back up the same 1719 Ex I/O network.
