PIC16F877 based controller with 4x20 LCD, 10base-T ethernet, 512KB SRAM, up to 512KB serial eeprom, 24 bit address and 8 bit data buses, and analog input.

Allows 1/4 watt 10 ohm resistors to be used as igniters. LED blinks the number of channels with conductivity. Independently opto-isolated inputs allow one IPB to be used with more than one altimeter/timer.

Reduces the holding current on valve solenoids to keep the coil cool and save the battery. Works on 12 to 20 volts.

Usually used in pairs to drop strap-on boosters. Bolt is a weakened 1/4-20 Nylon bolt. A small pyro charge (<0.2g on Pyrodex-P) is used to break the bolt. A new "015" o-ring and bolt is required for each use.

GSE for One hybrid pad. Temperature sensing for fill vent. Pad to LCO Sound/Voice. Up to 3000 feet over 4 pair CAT 3 or better cable. Outputs:Igniter (8 Amps), Fill valve, Dump valve, and Oxygen valve.

GSE for One hybrid pad. Temperature sensing for fill vent. Pad to LCO Sound/Voice. Up to 3000 feet over 4 pair CAT 3 or better cable. Outputs:Igniter (8 Amps), Fill valve, Dump valve, and Oxygen valve. Two auxiliary outputs and one input at the pad.

Uses 12 Volt "A23" battery for apogee only deployment with a low current igniter. PIC12F675 based, can be reprogrammed as a timer or camera trigger.

They come with a 1-1/2" cap and a bolt to hold them together. You supply the pipe that fits into the motor tube. They're clean, painted gray, new, 12" diameter V-belt pulleys found in the recycle bin. I machine the hub to hold the 1/2" nut.
They weigh ten pounds, so you're pay'n the shipp'n. Or, I'll deliver to a ROC or TCC launch.
