The Profile Controller offers both switching outputs in the form of SSR driver or Triac to drive external single or three-phase Solid-state relays or load contactors and linear analog control outputs in the form of (4-20)mA or (0-5)volt or (0-10)VDC, which can be used to control heater power through Thyristor Power Regulators (for an electrical heating system) or to control the position of a modulating motor valve (for oil or gas-fired heating systems). The analog outputs can be directly connected to Libratherm make single-phase/three-phase SCR based phase angle fired power controllers, which are ideally suitable for both resistive and inductive heating load. Additional 4 relays are also provided for time or temperature-dependent event outputs as per the system requirement. The programmed profile and other parameters are retained in the nonvolatile flash memory in the event of power failure.
To monitor the online temperature profile of the heating system, a serial communication port on the RS485 interface can also be optionally provided, the same can be connected to the computer.
Libratherm offers Microsoft Window-based Software to view the online behavior of the heating system in both graphical and tabular format on the computer screen.
