There are others. I use a SERDO8R purchased from EasyDAQ.com. It has an
RS232 interface and eight DPDT relays on a PC104 stackable profile. Current
price is $81, which I think is a bit much, but it is a well-constructed
board and is supported by National Instruments LabVIEW drivers (which I why
I have it). For $97 you can order it with eight programmable digital inputs
or outputs that operate in parallel with the eight relays.
I think Denkovi has a broader range of products with more interfaces and
lower prices. If I needed another relay interface I would buy the Denkovi
USB Eight Channel Relay Board ForAutomation, currently selling for $41, but
I have no experience with them.

Subject: [Elecraft] Relay boards for remote control?
Hi
Can anyone tell me what would be the most popular rs232 (or USB) relay
board for use in computer control of a k3 setup? I use the canakit 4 relay
USB board. Are there others?
Thanks
