← Back to productsProduct overview
The Allen-Bradley 1756-OH8I is a ControlLogix DC (90…146V) isolated output module for the 1756 chassis. It has eight individually isolated outputs for 125V DC loads, wired sinking or sourcing, with an operating range of 90…146V DC, up to 2 A per point and 8 A per module at 60 °C (140 °F). It draws 210 mA at 5.1V DC and 2 mA at 24V DC from the backplane. Field wiring goes through a 1756-TBCH or 1756-TBS6H removable terminal block, which is ordered separately. 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.
