Roc-2015 Controller Manual Pdf Link
The relay outputs are dry contacts (no internal voltage). While they are rated for 5A/250V, the manual stresses that these are suitable for "阻性负载" (resistive loads). For inductive loads (coils, contactors, solenoid valves with high inrush current), engineers must install external arc suppression (snubbers) or intermediate relays to protect the controller's internal contacts.
ROC-2015 Controller: The Ultimate Guide and Operation Manual
The ROC-2015 controller uses a "dry contact" system for its inputs and outputs, meaning it works with switches that do not supply power to the controller. Detailed wiring diagrams and explanations are provided in the official manual, but here is a summary of its connection points. roc-2015 controller manual pdf
Drives the raw water input solenoid valve.
Allows remote manual overrides or master PLC linkages to stop or start the RO run program. 2. Relay Output Control Assignments The relay outputs are dry contacts (no internal voltage)
Terminals for controlling the booster pump and low-pressure pump. 4. Troubleshooting Common Issues
The ROC-2015 serves as the central brain for single-stage reverse osmosis systems. It is designed to provide automatic operation management for small-scale RO water treatment systems by integrating electrical conductivity monitoring with electromechanical sequencing. The controller is the successor to earlier models such as the RO-2008 and RO-2003, offering improved reliability and graphical interface updates. ROC-2015 Controller: The Ultimate Guide and Operation Manual
After conducting a thorough search, I found that the "ROC-2015" controller is a product of the company "Delta Electronics". The ROC-2015 is a programmable logic controller (PLC) that is widely used in industrial automation applications.
Proper execution of the electrical terminal layout prevents back-EMF feedback and protects internal microchips from voltage surges. The terminal layout is divided into digital sensor inputs (low voltage) and relay control outputs (high voltage).
