Installation notes
- The DI Mass Connection Board (single) provides an interface to the simplex Series 2 DI, 32-Channel, 24 VDC, Dry Contact card used with the M-series 40-Pin Mass Termination Block.
- Two DI Mass Connection Boards (single) (DI Mass Connection Solution (two)) are required to provide the interface to all 32 channels on the Series 2 DI, 32-Channel, 24 VDC, Dry Contact card.
- Two, 20-pin ribbon cables (one per board) connect between the DI Mass Connection Solution (two) and the 40-pin Mass Termination Blocks.
- Four screw terminals provide the connections for +24 VDC power and ground.
- For dry contact mode, connect your device to the screw terminals labeled A1 - A16 and to the screw terminals labeled B1-B16. Refer to Figure: Wiring for dry contact mode for a wiring diagram.
- For isolated power mode, connect your device to the even numbered screw terminals labeled B1-B16 and connect external ground to the ground bar. Refer to Figure: Wiring for isolated mode for a wiring diagram.
