INFICON modules: PGE300, PGE500,
RS485 / RS232 - ASCII protocol
IG sensor on/off status message is displayed on the front panel, by serial commu-
nications and by SPDT relay (DIGITAL I/O Connector) rated at 1 A at 30 V (dc)
resistive, or 1 A at 30 V (ac) non-inductive.
IG degas on/off status or IG error conditions are displayed on the front panel, by
serial communications and by an open collector transistor output (ground emitter)
rated at 40 V max. VCE, 50 mA IC max.
IG filament switching User selectable between filament 1 or 2 using
the front panel soft-keys or RS232 / RS485
