TEC Controller

[Photonbeam]

TE Technology TC-24-25 temperature controller.
Features:
● Input voltage from (12 to 28) VDC
● Self-contained, (0.1 to 25) A current rating
● computer programmable via RS-485 communications port
● Bi-directional, solid state H-bridge operation for heating and cooling applications
● Control temperature of –20 °C to +100 °C using MP-2379 thermistor (supplied with controller)
● Proportional (P), Integral (I), and Derivative (D) control that can be selected as P, PI, PD, or PID; or
Deadband (on/off) with an adjustable hysteresis
● Temperature resolution of 0.1 °C or 0.1 °F
● Control stability of up to ±0.1 °C or ±0.1 °F (when controlling a cold plate)
● Pulse-width modulation of output:
● Selectable modulation frequency of 675 Hz or 2700Hz
● Controls up to 680 W
● 1500 VAC isolated RS-485 communications interface
● Set temperature selectable:
● computer set with controller stand alone operation
● Remote user set temperature using a potentiometer
● 0 mA to 20 mA current loop
● 0 VDC to 5 VDC adjustable range
● Differential temperature control
● No computer programming experience required to use the communications software program
(Supplied software is compatible with Windows 95/98/XP/NT)
● Command set is provided so programmers may create their own software interface or embedded
controller applications
● Versatile alarm system:
● Hardware output 5 VDC at 25 mA
● Alarm cancel is selectable via computer-software communication or remote contacts
● Second sensor also configurable as a heat-sink over-temperature shut-down
● Non-volatile memory retention of parameters (1,000,000 write cycles maximum; see command #31
in Appendix C for further details.)
● Operating temperature range of 0 °C to 65 °C
● Storage temperature range of -55 °C to +105 °C
RS485 to USB adapters are less than $10.
