Frequently Asked Questions

What is the key advantage of this 32-channel module?

• The 140DAI35300 doubles the input density in one slot. It provides 32 channels for space-constrained Quantum systems needing high I/O counts.

How does grouping affect wiring and isolation?

• The 4 isolated groups allow separate wiring sections. Each group has 1780 Vrms isolation from other groups and the backplane for safety.

What is the main difference from the 16-channel version?

• This module has twice as many inputs (32 vs 16). It requires 2 input words for addressing and has higher power dissipation at 10.9W.
