Digital Indicating Controller DB2000 - 1

DIGITAL INDICATING CONTROLLER The DB2000 series is a 96×96mm digital indicating controller with the indicating accuracy of ±0.1% and the control cycle of approximately 0.1 seconds. The configuration of highly functional system is enabled by various options including 2 transmission signal outputs, 2 communications ports and arbitrarily-allocation of digital inputs. FEATURES Large easy-to-view 5-digit display Process value (PV) and set value (SV) are displayed by large easy-to-view 5-digit display indicators. The resolution of 0.1°C is enabled for more than 1000°C. Highly-functional operation screen and settings screen The controller inherits the operation screen and the settings screen adopting the LCD (liquidcrystal-display) which has been familiarized for long time. Furthermore, the screens have become high-definition and highly sophisticated. READY function provided Although the DB2000 series is the constant value controller, switching to the state (READY) that any control is not wanted is enabled. In addition, the output value (MV) at READY can be set arbitrarily. Outstanding controllability Two types of PID algorithms, the position-type PID algorithm and the speed-type PID algorithm, have been installed. You can select the optimum PID algorithm for an object controlled. DI arbitrarily-allocation When the digital input (DI) is added, arbitrarily-allocation for assigning functions to those DI's is enabled. It is the function enabling allocations such as [READY/RUN] to DI1 and [Manual output operation/Automatic output operation] to DI2. Versatile control functions provided Versatile control functions, such as the automatic PID system, which executes control by PID parameters preset at every SV sections, and selection of the 2-output control system from PID system and split system for 2-output types, are available. Communications 2-port type provided Models with 2 communications ports are available. In addition, speeding up and highly-functionalization of communications have been realized. For example, you can use 1 port for high order communications with a personal computer and another port for the communications remote (digital remote) function. The communications protocol can be arbitrarily selected from [MODBUS] and [PRIVATE]. Transmission signal 2-output type available 2 types of transmission signal output, the high-precision type (0.1% of full scale) and the general type (0.3% of full scale), are available. Transmission signal 2-output types with these 2 transmission signal outputs and models with transmitter power supply are available. Heater disconnection alarm The heater disconnection alarm can be added to ON-OFF pulse types or SSR drive pulse types only. By connecting the designated CT externally, the current value of heater is measured and can be indicated on the operation screen. Other functions Various functions including multiple auto-tuning, timer function using the digital input (DI), control loop abnormality alarm and user calibration are built-in. Conforming to international safety standards and European directives (CE) The controller is in conformity with European directives (CE), and is UL and c-UL approved. Conforming to RoHS The controller is an environmental consideration product which does not contain directed hazardous substances such as lead, etc.
