General Description

BTC-9300 is a versatile PID control available with multi-input:

and multi-outputs options (must be specified at time of ordering):

The BTC-9300 is available with 3 outputs, 2 from the list above as well as an alarm output.

The unit can be powered by 11-26V, or 90-264V supply. These controls have been around for many years and have a proven track record for reliability.

The BTC-9300 has Fuzzy Logic, PID microprocessors and incorporate a dual 4-digit (programable to 0.1'C or 1'C) LED display which indicates the process and set-point values.

The Fuzzy Logic technology has an auto-tuning function that determines the correct proportional band, rate and reset values to enable the process to reach a predetermined set-point in the shortest time, with the minimum overshoot during power-up or external load disturbance. The output can be a 2 amp relay, a 5V or 14V solid state relay drive, 0-10V or 4-20mA output.

4-20mA Retransmission is also available for BTC9300.

IP65 front panel.

Manual control of the output is also possible. Offset and shift functions allow process values to be readily corrected when there is a sensor error and on-site recalibrations are required.

All BTC models have programmable rate of temperature rise and an inbuilt timer that will bring a process up to temperature at a set rate and hold it for a predetermined time before switching off.
