General Description

BTC-8100 is a versatile PID control available with multi-input:

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

The BTC-8100 is available with 3 outputs, 2 from the list above as well as an alarm output relay.

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-8100 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 BTC-8100.

RS-485 communication port available.

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.
