for pneumatic and electric actuators Process controller 110-240V Process controller dtron 316 in Rittal-cabinet with current loop sensor input for controlling pneumatic and electric actuators with a position controller via the 4-20 ma output Features Rittal cabinet RAL 7035 dtron 316 process controller Sensor input for current loop Power supply 110 V-240 VAC On / off switch Options: -Profibus card Data sheet 000023 englisch
Working principle The controller has two four-digit, 7-segment displays for process values (red) and setpoints (green). The displays can be used to add comments when you program your inputs. The controller has one analog input for any common transducer type, two relay outputs, two combined binary inputs / logic outputs and one 4-20 ma analog output for controlling actuators. One free slot is provided to allow an additional option, such as a Profibus card, to be retrofitted if required. The controller is also equipped with four limit comparators that can be assigned to the source signals. You can choose between eight different limit comparator functions. One program function with eight program segments and two autotuning (self-optimization) methods (oscillation and step response) are provided as standard. Process controller dtron 316 Key features - Programmable analog input - 2 autotuning methods - Program function with 8 segments or ramp function - 2 timer functions - 4 limit comparators - Key and level inhibit - 4 programmable setpoints, 2 parameter sets - 4-digit resolution (max. 2 decimal places) - Controller structures: P, PD, PI or PID - Process value inputs for all common transducer types (see technical data) - 2 relay outputs 230 V / 3 A (NO) - 2 combinable binary inputs / logic outputs - Analog output 4-20 ma Function diagram Input resistance thermometer Resistancetransmitter Thermocouple Current 0(4)...20mA Voltage 0(2)...10V 4... 20 ma or 2
