Agilent E3120-66512, a plug-in pin board that switches signals through twelve Sanyu Switch relays. The relays sit in rows between aluminum shield boxes, with gold coax connectors on the edges and a multi-row backplane connector at the other end. Also searched as E312066512 and E3120 66512.
What is on the E3120-66512 board?
Eight Sanyu URT-P12912GTN-04 and four URM-P22912GTN-04 relays, designators K10 to K42 on the back. A logic section with one large QFP chip (U5) and two smaller ICs (U1, U2) drives them. A short gray coax jumper links two shielded bays, and a white lever helps pull the card from its slot.
Which Agilent instrument does it fit?
We could not find an Agilent document for E3120-66512, so we do not name a system. The "-66512" suffix is Agilent's style for a PC assembly. Match the number on your old card: E3120-66512 is silkscreened on the front and printed on the back label.
What does a relay board like this do?
It connects and disconnects signal paths on command, so one instrument can reach many test points. The shield boxes around each relay pair keep the switched lines apart.

What is a relay board?
A circuit board of switches that an instrument opens and closes electronically to route signals between test points.
Is a Sanyu reed relay the same as the relays fitted here?
Sanyu Switch makes reed relays, but we found no public datasheet for URT-P12912GTN-04 or URM-P22912GTN-04, so we do not state the relay type.
Is E3120-66512 the same board as E312066512?
Yes. It is the same part number written without the dash.
