Ahlborn ALMEMO 2290-8, Руководство по эксплуатации

Страница: 16 / 52

The 5 analogue inputs are electrically isolated by using
photovoltaic relays and a potential difference of 50V DC or 60V
AC, at maximum, is permissible between them. However,
sensors combined within one connector and sensors with an
own power supply are electrically connected to each other and
must, therefore, be operated in isolation. The voltage applied
to the measuring inputs must not exceed
±
5V (between B,C,D
and A or - respectively).
The cold junction compensation for thermocouple measurement is integrated
in socket CH0 of the device.
