3165 - 8-Channel PC Controlled Relay Board WITH BOX
Front
|
Back
|
Essentially exactly the same as our project Order Code
3074 but supplied fully assembled in a high quality plastic case.
This PC relay board provides independently programmable 24/7 timer control
for each of the eight onboard mains rated relays. Relay outputs can be used
to automatically turn On/Off lights, motors & other devices around the home,
office, laboratory or factory. The software interface allows you to program
and save an infinite number of On/Off sequences. Alternatively, you can write your own software
with a DLL from
http://www.logix4u.cjb.net/.
Each relay output is capable of switching 5 amps (see
Relay Spec Sheet) and has an LED to indicate it's status. Relay outputs
have high quality detachable screw terminal block connectors. Can be used with
any PC parallel port on a 286 upward (remember those?).
All components provided including a high quality case with pre-punched
and silk screened front and rear panels to give the product a professional
and attractive finish as shown in the photos.
NB If this board is powered up and connected to the computer,
all of the relays will momentarily turn on when the PC first boots up. If this
is a problem, please look at our 8-Channel Serial Port Isolated
IO Relay Controller instead.
