Temperature Controller- Series 8500
1/8 DIN, Horizontal or Vertical Format. Microprocessor Based, Fully Programmable, Self-Tune® PID
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.
