Terminal Blocks
The IB1004 and the SB1004 have four terminal blocks in total, two on each board. There are nine terminals in each terminal block.
- All A/D inputs are grouped into terminal blocks 1 and 2
- All D/A outputs are on terminal block 3
- Relay outputs and the serial port are on terminal block 4
