PLICSRADIO T61 • Wireless emitting unit (single channel)
32865-EN-130322
Information:
Two-wire or four-wire instruments can be connected. In the menu you
can switch over between active (standard setting) and passive opera-
tion of the measuring data input. The connection assignment is the
same for both modes.
•
In active mode, PLICSRADIO T61 provides the voltage supply for
the connected sensors. This mode is for connection of pressure
transmitters without separate operating voltage (sensors in two-
wire version).
•
In the passive mode, the sensors are not powered - only the meas-
ured value is transmitted. This input is for sensors with their own,
separate operating voltage (sensors in four-wire version). On a
PLICSRADIO T61 in Ex version, the passive input is not available
for approval/technical reasons.
