Dwyer Series 8500 Temperature/Process
Control |
| 1/8 DIN, Microprocessor Based,
Horizontal or Vertical Format, Fully Programmable |
| |
The Dwyer Series 8500 Temperature/Process
Control provides an impressive selection in a compact,
economical 1/8 DIN package. Choose from two case styles
in horizontal or vertical formats. 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, ,
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. |
