The JUMO exTHERM-DR is a two-state controller for heating or cooling applications. The intrinsically safe Ex [ia] measurement input allows the direct connection of the corresponding type tested probes. Use of a barrier is no longer required.
Other than the relay output "Controller" K1 JUMO exTHERM-DR also has the second relay output K2. It signals when limit values have been exceeded or are not met.
Alternatively, a binary signal of 0/10 V is also available for the controller output or the limit value signaling.
The current measured value or the setpoint value is issued via the standard analog output. The vibrant display for plain text and backlight shows information about measured value, setpoint value, etc. in a clearly-arranged manner. A clearly-structured operation setup enables quick configuration and thereby reduces the startup times.
Alternatively, the configuration and parameterization can also take place via a setup program and the standard USB interface.
