The 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. Programmable alarm can act as high or low or high/low guard band alarm. 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 field replaceable without wiring changes thanks to removable front panel.
