BTC Temperature Controls, BTC9090 BTC2220 BTC8120

The BTC9090, BTC9100, BTC8100 & BTC9300, BTC2500 Fuzzy Logic, plus PID microprocessor controllers, incorporates a dual 4-digit LED display, indicating process and set-point values. The Fuzzy Logic technology enables a process to reach a predetermined set-point in the shortest time, with the minimum of overshoot during power-up or external load disturbance. The BTC9300 & BTC2500 have an IP65 front panel

Wide selection of sensor/inputs/types (thermocouple types K, J, T, E, N, B, R, S or Pt100).

Furthermore, the BTC9300 & BTC2500 may be configured for current or voltage inputs.

Manual control of the output is also possible. Offset and shift functions allow process values to be readily corrected for sensor errors and on-site recalibrations.

The dual 4-digit LED display has a fully programmable decimal point, therefore, they can be configured for 0.1'C or 1'C temperatures. The controller incorporates an auto-tuning function that determines the correct proportional band, rate and reset values to provide accurate control with the minimal of overshoot and temperature oscillation.

Powered by 20-32V or 90-264V supply, each unit can be supplied with various outputs depending on the application. These can be a 2 amp relay, a 5V or 14V solid state relay drive, 0-10V, 4-20mA outputs.

4-20mA Retransmission is also available for BTC9100, BTC8100, BTC9300 & BTC2500

All models have programmable rate of temperature rise and an inbuilt timer that can maintain a temperature as long as required before switching off.
