Ryan Spooner, Manager of Instrumentation and Automation for Singer Valve said, “Everything you can think of wanting in a control panel, we have incorporated into this Single Process Controller and we’ve made it easy for anyone to use with a colour touch screen interface.” The SCP-TP is easy to setup in the field and Singer also offers onsite commissioning assistance and training for utility staff if needed.
The SCP-TP Controller is designed to complement a dual solenoid control valve and can switch easily between settings for level control, upstream and downstream pressure management, flow control and position control. The SCP-TP also offers ON/OFF control and can be configured with a 4 – 20mA control motor such as the Singer 420 DC pilot mounted control motor. The SCP-TP is equipped with easy to use digital input controls and user selectable digital output alarms. Added features such as data logging, which logs all sensor feedback and set-point data as well as trending graphs, can be used for system analysis for water loss prevention and overall system pressure management.
The SCP-TP Controller reads and compares the process feedback (process variable) 4 to 20 mA signal to the desired setting (set-point) which is set either locally on touch screen or remotely via 4 to 20 mA signal. The SCP-TP then accurately positions the valve to bring the process variable towards the set-point until they coincide. The SCP-TP has the capability to retransmit the process variable via a 4 – 20mA signal and is equipped with both Serial and Ethernet Modbus capabilities for remote SCADA control and monitoring.
