Two single-pole, double-throw (SPDT) relays. Use potentiometers and test
points on the module front panel and jumpers inside the module to
configure relays.
• Relay 1 is assigned to the Convectron gauge, which indicates vacuum
chamber pressure
• Relay 1 activates with decreasing and deactivates with increasing
vacuum chamber pressure
• Hysteresis: 30 mV
• Range: 1 x 10
• Relay 2 is assigned to the differential pressure sensor, which indicates
pressure differential between atmospheric and vacuum chamber
pressures
• In default mode, relay 2 activates with increasing and deactivates with
decreasing differential between atmospheric and vacuum chamber
pressures
• Hysteresis: 8 Torr
• Range: –750 to +125 Torr
