Switch reference document number: 5968-9653E 34946A Option 001 contains cables and connectors to support two of the supported switches listed above. 34947A Option 001 contains cables and connectors to support three Keysight N1810UL switches. The 34946A and 34947A modules do not connect to the analog buses. Instead, all connections are made through the visible SMA connectors via external cables. - Page 12 Micro-Coax http://www.micro-coax.com S. M. Electronics L.L.C. http://www.smelectronics.us The 34946A and 34947A support only 24 VDC coil options for the N1810 CAUTION switches. If the proper voltage option (Opt. 124) is not used, the switches could be damaged. The 34946A module (Options 004, 020, 026) has two independent Keysight N1810TL switches.
