In 1989 SattControl Instruments bought NAF instruments, at this time, two new instruments were introduced

We still have spare parts for both instruments and would be able to repair and calibrate them.


ECA40x Controllers

Contains of ECA40, ECA04 & ECA400 controllers.
(Fisher Controls DPR900,  & DPR910)

  • PID control

  • Autotuner

  • Gain scheduling

  • Feed forward

  • Analogue or pulse output

  • Serial communication

  • Configuration from front or PC

  • Process value alarm

  • Deviation alarm

The ECA40 is a single-loop sampling PID controller with both autotuner, gain scheduling and configurable functions.  Function configuration means that the user can decide how different input and output signals can be utilized, and choose externa] control possibilities, whether the output signal shall be analog, two- or three-state pulses, if temperature sensors should be directly connected etc.  The controller is delivered with a basic configuration, so that it can be used immediately as a standard PID controller. The sampling time is 200 ms, i.e. all the inputs and outputs are checked and updated five times a second. The controller can communicate with a centralcontrolling system via an RS485 serial data communication channel.  The host system can both read and control the ECA40.The output signal and set point can also be controlled by two digital inputs.  A remote analog set point, or an additional internat set point, can be used instead.  Switching between different modes, such as Auto/Manual or Local/Remote, can be controlled by externat digital signals.  Alarms and choice of mode are indicated externally by digital output signals. The terminal block, to which all signals and the mains supply are connected, is mounted in the controller cassette.  The controller unit is connected automatically via plug-in contacts when inserted in the casing.  When a controller has to be changed, there is thus no need to disconnect any cables or disturb the electrical installation in any way. All settings, controls, readings etc. are on the front panel. Condensed operating instructions, which can be used as a memory aid during day-to-day operation, are located in a slot above the controller.
