HT 55 - Self-Optimizing Microprocessor Regulator
Small format powerful regulator at a reasonable price.
After mounting into a front panel, the regulator front will achieve protection category IP 65. For measuring value input you can choose from 15 sensor types and linear signals. The regulator output is designed to trigger an electronic relay. Two further relay outputs can be used as alarm contacts or for direct switching of small loads. The “self-optimization” function determines the optimal regulating parameters for the heating task – on demand, the setpoint is approached with a ramp function. HT 55 can be operated with 4 buttons or with a service interface and optional Windows software. With LED display for actual value, setpoint value, control deviation and switching state of the outputs. The regulator configurations can be protected using passwords.
With order number 065515 current monitoring can be realised.
Prepared for triggering an electronic relay. The available relay contact is used as an alarm contact for current control.
