1 Introduction
1.7.2 Modules
The proven input and output modules are available as module variants (type 7050xx; incl. controller
module).
For example: the analog input module with universal inputs for thermocouples, RTD temperature probes,
and voltage or current standard signals. As a result the same hardware can be used to precisely acquire
and digitize a highly diverse range of process variables.
JUMO variTRON 300 enables simultaneous operation of up to 32 control loops so that it can also be
used for sophisticated processes. Through expansion slots the inputs and outputs of each controller
module can be individually expanded and adapted. The control loops here operate fully independently,
which means they do not require resources from the central processing unit.
Thyristor power controllers can also be connected via EtherCAT or PROFINET. In addition, JUMO dig-
iLine sensors for liquid analysis can be connected to the central processing unit.
Wireless transmission of measured values
As of system version 5, the central processing unit JUMO variTRON 300 is also available with a wireless
interface that enables wireless transmission of measured values. The transmitters of the JUMO Wtrans
series are available as measuring probes (Wtrans T, Wtrans B, Wtrans p). A maximum of 32 transmitters
can be operated on the central processing unit.
During startup, the display of the RSSI value (Received Signal Strength Indicator) in the Web Cockpit is
helpful as an indicator of the signal strength of a received radio telegram.
