SK08_T8

KNX sensor / controller 8-channel temperature for measuring and controlling up to eight temperatures.
The SK08-T8 can be used to connect platinum measuring resistors PT1000, PT500 or PT100 of any design.
Mixing the different measuring resistors is not possible.

Application:
Monitoring and control of temperatures for heating and cooling purposes as well as for logging. 
The KNX sensors are commissioned using the ETS (Tool Software) in conjunction with the associated application program.
The devices are unprogrammed when delivered.
All functions are configured and programmed via the ETS.
The controllers can be switched on or off via activation or blocking objects via the KNX bus.

Features:
8x temperature readings with:
Two-point controller with switched or pulsed 1-bit output or
PI controller with continuous 8-bit or pulse-width modulated 1-bit Output
Cyclic sending of the manipulated variable (parameterizable)
All controllers with enable or disable object (parameterizable)
Limit alarm for upper and lower limits
Auxiliary variable for changing the setpoint or limit values ​​via the bus
Calibration of the sensors (offset adjustment)
