ELECTRIC CONTROLS
Controller
This driver is designed for applications in hazardous areas, direct connection of sensors and actuators has three analog inputs 4 to 20 mA, two analog outputs 4 to 20 mA, six digital inputs and outputs, cascade control, ratio control, control double loop control, the difference, 16 steps depending on programmer’s reference point.
The controller has special features for the jacket / heating systems products for use as station manual / automatic processing set point, Modbus interface. Intrinsic safety controller of a single loop that can be installed directly in hazardous areas. Its presentation is variable, process setpoint, deviation control, output and display Automatic / manual.
The controller operated by 8-key front panel has:
– Direct connection of sensors and actuators in the danger area.
– Three analogue inputs 4 to 20 mA (3 – wire).
– Six digital inputs to switch roles.
– Six digital outputs for alarms.
– Modbus interface for communication with a control system.
Special software functions:
– Cascade control, ratio control, contrast control, dual-loop control.
– As a dual loop controller, the controller provides two output signals in parallel or, alternatively, the lowest, respectively, the highest of each.
– Special functions for temperature control of batch reactors, for example, limiting the difference between the jacket and the temperature of the product and prevent lots of excess temperature.
– Integrated automatic 16.
– Role of the steps set point programmer.
– Special functions for use as manual-/automático station or as a regulator setpoint.
