The 998 / 999 series offers two
independent loops of PID control in one horizontal or vertical
1/8 DIN package. The control features two thermocouple or universal
process inputs with an 5 Hz sampling rate. Auto-tuning PID and
burst fired outputs make for smooth precise control. The optional
six outputs allow up to two zones with heat / cool and alarm outputs.
All of these features packaged behind a rugged NEMA 4X front panel
make the 998/999 a useful process control tool.
