PID controller Tecnologic TLK94 LIRRR with analogue current output and three relays

Ascon Tecnologic TLK 94 is a microprocessor controller with ON/OFF control, neutral zone ON/OFF, PID with single or double acting control (direct or inverse function) and PID for servo drives. It is also equipped with fast AUTOTUNING function, SELFTUNING function and automatic parameter calculation for FUZZY CONTROL in PID control.
PID control is performed in a two degree-of-freedom algorithm and optimizes the function of the instrument independently of disturbances in the controlled processes and changes in the setpoint.
Furthermore, the controller optionally allows communication over the RS485 serial communication link via the MODBUSRTU public protocol with a baud rate of up to 38,400 baud.
The actual value is shown in red on the upper 4-digit display and the setpoint in green on the lower 4-digit display. The status of the outputs is indicated by 4 LEDs.
The controller allows 4 setpoints to be stored in memory and can have up to four outputs: relay, solid state relay SSR or up to two analog outputs.
The input of the device is universal, programmable and it is possible to connect thermocouples (J,K,S,B,C,E,L,N,R,T), resistance sensors Pt 100, thermistors PTC and NTC, infrared sensors Tecnologic IRS and all standardized analog signals (0/4...20 mA, 0/1..the controller can be equipped with a current transformer at the input that measures the current through the load - HEATER BREAK ALARM function and a programmable digital input instead of the OUT4 output.

Other important features of the Ascon Tecnologic TLK 94 controller are:

• control loop failure alarm
• control power regulation
• control of control power speed change
• reaching the setpoint at the selected speed
• ramp and delay function
• softStart function
• pC configuration and parameter protection with different access levels
