Terminal blocks

Top Previous Next

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.
