DMC10 Distributed Multi-channel Controller - 1

Distributed Multi-Channel Controller The DigitroniK DMC10 is a module type 2 or 4-channel compact digital controller. Inputs are full multiple, supporting thermocouple, RTD, DC voltage and DC current inputs. Control mode is time proportional (ON/OFF) PID control. Control outputs are relay output and voltage pulse output. Continuous PID control is attained by an auxiliary output, A dedicated PC loader configures setup, control parameters • Full multiple input function is equipped, supporting vari- ous analog input sensors. • Communication function (RS-485) is provided as stan- dard. Communication performance is enhanced by sup- • Two event outputs are available for each channel. "AND/ OR" logic is used as an event between channels by the internal event function. (Under development) • Current transformer (CT) input is provided for each chan- Easy setting by a personal computer loader, also enabling monitoring of trial operation. Connector type and terminal type models available for the A side-face connector is used to connect modules, there- fore communication and power wiring is not required. "Quick-FITTER" Control, a high-speed recovery control function is equipped as standard. This function enables the quick recovery of setpoint temperature and over-shoot suppression at the occurrence of disturbances.
