This module performs in a rigid wiring system where the user connections are made to terminal strips attached to the front of the card basket. The I/O modules slide in slots of the card basket and make contact with the terminal strips via the mating connector.
User connections are made to standard screw-type terminals capable of securing up to two AWG 14 solid or straded wires per terminal. Terminals are numbered from one at the top to 20 at the bottom as shown in the figure.
The data bus connections are made via the standard OURBUS interface connector to a shielded backplane at the rear of the card basket. The module may be placed in any location in the I/O struction without interfering with any other module´s operation. When the module is inserted into the card basket, it picks up a low impedance earth shield ground by connecting the module´s shield to the backplane´s earth shield ground.
Terminal Numbering and Output Connections
The following figure shows typical circuit connections for power applications of the B842–008 module.
NOTE: Since each output is isolated from the remaining outputs, separate power sources can be used for each load. Each output can be wired for current source or current sink operations.
NOTE: It is possible to have the active indicator lit with one or more output channels working improperly.
