Elec tronic Controller TR870 Series
Features PID and Auto-Tuning
The Trerice TR870 Series Electronic PID Controller is designed for use on applications where large load changes are expected, or the need for extreme accuracy and fast response time exists. With full auto-tune capabilities and a large selection of available inputs, the TR870 Series is ideally suited for use with a Trerice Control Valve.
