The Pixsys ATR243 is a microprocessor controlled controller with one selectable input, configurable outputs and a power supply in the range of 4...230 Vacdc. 18 types of sensors can be connected and the outputs are configurable: 3x relays, 1x SSR or analog output 4...20 mA and 0...10V. Specific features include Soft-Start function expressed by step/time ratio, logic for servo drive control (double PID control), possibility to set up to 4 setpoints, pre-programmed Start/Stop cycle with two/three steps. Configuration is possible using a Memory card key with internal battery and it is not necessary to connect the controller to the power supply. This model is also equipped with RS485 Modbus RTU serial communication link and, using a measuring transformer, a load fault monitoring function. Configuration is possible using either pushbuttons or a Memory card key with an internal battery, where the controller does not need to be connected to the power supply as is usual with competing controllers.
