The 1336F-MCB-SP1F PCB Main Control Board by Allen-Bradley is the main control board for the Allen-Bradley 1336 Plus II Frame B to G drives, which houses the control interface boards and other RIO boards. The main control board coordinates all the functions of the drive, and it has various ports for connection to peripheral devices (for example an HIM is connected to the drive-through Port 1 on the main control board) and a drive nameplate is located on the face of the main control board. The 1336F-MCB-SP1F main control board connects to the control interface board using the J2 and J4 jumper connectors located on the lower side of the board and also on the bottom of the main control board is the terminal block (TB2) with 22 positions and with 0.3 mm2 (14 and 22 AWG) wire size. The 1336F-MCB-SP1F is installed by placing the board on the mounting plate and by tightening the 11 screws holding the main control board to the mounting plate with a 26in-lb (3N-m) rating. Various wires from the terminal block (TB2) are connected and ground wires, an 8-pin connector from HIM Mounting Plate, and the J1, J2, J6, and J8 jumper connectors are connected to the main control. Also, wires from the TB3 terminal block are connected and the board has LED indicators that show the status of various connected boards. The HIM cradle is installed on the board with 4 tightening screws, with the control interface board also installed on the main control board, and the communication connector on the J3 connector is also attached.
