The Series
8500 Temperature/Process Control provides an
impressive selection of features in a compact, economical
1/8 DIN package. Features include on-off, time proportioning,
proportional, PI, PD or full PID control - fully programmable
from the front panel - or use Self-Tune PID. Inputs are
selectable from a variety of thermocouple types including
J, K, T, E, N or L; DIN NIST or Ni RTD’s. Output choices
include solid state relay, mechanical relay, 5 VDC - ideal
for driving an external SSR - or isolated 4-20 mA proportional
current. An optional programmable alarm provides a full
array of alarm action configurations including high alarm,
low alarm and high/low guardband alarm. Manual reset, power-up
inhibit and power interrupt reset provide additional alarm
flexibility.
A water and corrosion resistant front panel
(NEMA 4X, IP65), input fault timer, digital input filter,
Self-Tune ramp to setpoint, four password protected security
levels and °F or °C display selection are all standard.
Entire electronics package is easily field replaceable without
wiring changes thanks to the removable front panel.
