FrmrSpecialist may be right but I would just check to see if they require similar voltage, to little it wont work, to much you may fry it out after a while. Typically you can look that info up pretty easy.
The nt solenoid is 5 volt .8 watt solenoid, while PE's geo 2 board is designed to run a 5volt 1.8 watt solenoid. While the board may push a higher wattage i highly doubt it will cause the solenoid coil to burnout prematurely... well at least not noticeably.
Thanks. For future reference, where do I go to look this stuff up? The place where I got most of my information was zdspb.com, but that doesn't contain stuff like that. I also couldn't tell if the NT solenoid was a bespoke solenoid as opposed to just a humphrey or something.
