Vega TP-11 / User Manual
For connect an external sensor contacts CL+ и CL- are used. Connection scheme see
on the picture below.
To save the battery life of the converter, the 24 V supply voltage is not continuously
supplied. The 24 V voltage is applied to the 4-20 mA device a few seconds before the polling
is performed so that the sensor can turn on and set the current corresponding to the
measured parameter. This time, the so-called "startup time", is a configurable parameter from
the configurator and can be set from 1 to 60 seconds.
The outputs OUT_1 and OUT_2 operate on the principle of open-drain and can be
used to control external devices, such as electric cranes, lighting, sirens and so on. The load
capacity of each output is no more than 200 mA.
Permissible load for each digital output is 200 mА
To increase the load on the device outputs, it is necessary to use an external relay. The
relay connection scheme is shown below.
