32-Channel Relay Switch Module for SCXI—The SCXI-1163R includes normally open, or Form A, optically isolated solid-state relays arranged into eight banks of four relays with one common pole for each bank. You can use the SCXI-1163R to switch high-voltage loads. The SCXI-1163R is programmed serially over the SCXIbus, so you can integrate SCXI-1163R modules into existing SCXI systems without additional devices or cabling. The modules can operate in parallel mode when cabled directly to a plug-in digital I/O device.
