The Allen-Bradley 1756-OB8K is a ControlLogix DC (10…30V) output module for the 1756 chassis. It has eight sourcing outputs in two groups of four for 12/24V DC loads, with an operating range of 10…30V DC, up to 2 A per point and 8 A per module at 60 °C (140 °F). It draws 165 mA at 5.1V DC and 2 mA at 24V DC from the backplane. Field wiring goes through a 1756-TBNH or 1756-TBSH removable terminal block, which is ordered separately. This K version adds conformal coating for harsh, corrosive environments. ControlLogix I/O modules can sit in any slot of a local ControlLogix chassis or in a remote chassis linked over EtherNet/IP or ControlNet, and their input data and output status can be shared by more than one controller.
