Don't know what happened to the links, but here are the Digikey part
numbers:

P&B KUEP11D15-12: PB840-ND (DPDT, 3A @ 150VDC, 12V coil: overkill for
KSI signal switching, but usable; recommend using the SPST KUEP3D15-12
equivalent part from EV Source for higher current (10A @ 150VDC)
switching applications)

Reed relay: 306-1024-ND (0.5A @ 200VDC, 12V coil: suitable for KSI
signal switching)

If you browse the Digikey catalog you will find other reed relays rated
to switch 300VDC (and one up to 7500VDC, I believe), but 200VDC should
be fine for the Curtis KSI since the Curtis only supports up to a 144V
pack.

If you are looking for a relay to control a heater element, the P&B
PRD-series relay is a good one to search for. I'm pretty sure Randy at
CEV will sell you one (he's also the place to go for the best quality
heater elements)

Hope this helps,

Roger.

For the PRD series I wound up going with the Potter & Brumfield PRD-11DH0-12. I've seen these anywhere from $10-$20 in various places.
Its rated for the task. For more than 120VDC you'd need to get the DPDT version (which is the part number above) and run serially though both sets of contacts. You'll wind up paying about $15 for a box/cover for this open frame relay.
