Series 2500 Temperature Process Controller |
| |
| |
 The
Dwyer Series 2500 Temperature Control provides an impressive
array of features in an economical 1/4 DIN package. Features
include on-off, time proportioning, proportional, PI, PD, or
full PID control, programmable from the front panel, or use
Self-Tune® PID. Input types are selectable from a
variety of thermocouple types (J, K, T, E, N or L) or DIN, NIST
or Ni RTD's. Outputs include solid state relay, mechanical relay,
5 VDC (ideal for driving an external SSR) or isolated 4-20 mA
proportional current. Optional programmable alarm can act as
high or low or high/low guardband alarm.
A water and corrosion resistant front panel (NEMA 4X; IP
65), 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 field replaceable without wiring changes thanks
to removable front panel. See

| *When ordering a control to operate contactor
or solenoid loads greater than 100 mA, the SSR output should
be selected instead of the Relay. If the Relay is selected,
also order part number A-600, R/C Snubber. |
