Simplex Discrete Output 40-Pin Mass Termination Block

Installation notes

The Simplex Discrete Output 40-Pin Mass Termination Block provides wiring terminations for a DO, 32-Channel, 24 VDC, High-Side, Series 2 Plus card.
Set the keys on the terminal block to B4 to match the DO, 32-Channel, 24 VDC, High-Side, Series 2 Plus card.
The mass termination block has two, 20-pin IDC headers that split the 32 channels into two, 16-channel headers. Each of the two-row headers accept a 20-pin 1-for-1 passthrough cable with 2x10 header connectors.
The return connection is made internally between the mass termination block and the DO, 32-Channel, 24 VDC, High-Side, Series 2 Plus card. No external wire is required.
