Delta DTC1000R & Delta DTC2000

Description

The Delta DTC1000R & delta DTC2000 is a temperature controller from Delta Electronics, designed for precise temperature regulation in various industrial applications. It is part of Delta’s DTC series, which includes digital temperature controllers known for their accuracy, reliability, and ease of use. Below is a comprehensive overview of the DTC1000 temperature controller, including its features, specifications, applications, and usage.

DTC1000 is an OPEN-TYPE PROCESS CONTROL EQUIPMENT and DTC2000 is an OPEN-TYPE PROCESS CONTROL ACCESSORY. These devices are microprocessor-based temperature control controllers that can be provided with normally closed and/or open contacts.

Temperature can be controlled separately by two group outputs: cooling (forward) or heating (reverse). When dual loop output control is used, the two output controls will be designed for cooling (forward) or heating (reverse). If two control outputs are conducted in the same direction, only the 1st group control period is valid. Control methods: PID control, ON/OFF control, manual control and PID program control.
