Temperature/Controller

1/4 DIN Fully Programmable, Self-TunePID

The Love Series 2500 Temperature Control provides an im-

pressive array of features in an economical 1/4 DIN package.

tures include on-off, time proportioning, proportional, PI, PD, or full

Temperature

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 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 pass-

word 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.

SPECIFICATIONS

Inputs: Thermocouple or RTD.
Input Impedance: Thermocouple = 3 megohms minimum, RTD current =

200 µA maximum.

Operating Temperature: 14 to 131°F (-10 to 55°C).
Memory Backup: Non-volatile memory. No batteries required.
Control Output Ratings:

SSR: 2.5A @ 240 VAC resistive at 77°F (25°C). De-rates to 1.25A

@ 130°F (55°C).

Relay: SPDT, 10 A @ 240 VAC resistive.
Switched Voltage (non-isolated): 5 VDC @ 20 mA.
Proportional Isolated Current: 0-20 mA, selectable, into 600

Ohms maximum.

Control Action: Selectable for reverse (usually heating) or direct (usually

cooling).

Ramp: One ramp time adjustable from 0-100 hours.
Isolation: Relay and SSR outputs; 1500 VAC. 0-20 mA output; 500 VAC.

5 VDC output is not isolated.

Front Panel Rating: NEMA 4X (IP65).

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