Product-Specific FAQ
Model-specific scope, verified data and ordering boundaries.
01

What measurement current is used for resistance-type transmitters?

The Siemens record gives a typical constant measurement current of 1.67 mA.

02

Can thermocouple temperature compensation be configured?

Yes. Internal compensation, an external compensation socket and a definable comparison-point temperature are listed.

03

What are the input destruction limits?

The voltage input permits 20 V continuously or 75 V for one second at the stated duty ratio; the current-input limit is 40 mA.

04

Which interference frequencies correspond to the selectable integration modes?

The published suppression frequencies are 400, 60, 50 and 10 Hz.
