The Allen-Bradley 1756-OB16I is a ControlLogix DC digital output module that has Sixteen (16) individually isolated points. It does not have internal however, external IFM can be used to protect outputs. The recommended fuse type for this module is the 5x20mm 4 A quick-acting fuse supplied by with part number SOC p/n MQ2-4A. For the 1756-OB16I module, compatible Remote Terminal Blocks (RTB) are 1756-TBCH 1756-TBS6H, which both have 36 pins. RTB are required to provide signal termination point. The output channels of this module feature a configurable safe state position ne the controller’s mode is changed to Program and Controller fault.
