PLICSRADIO T62 • Wireless emitting unit (multiple channel)

32624-EN-130228

PLICSRADIO T62 offers connection options for max. three continu-

ous sensors and two switching instruments.
Individual instruments with switching output can be used. The output

can be a relay, NAMUR or transistor output (Open Collector)

Up to three HART sensors in multidrop mode can be connected to the

HART input (terminals 3/4) (input 1 … 3 corresponds to HART addr.

1 … 3). If in addition the 4 … 20 mA input (terminals 1/2) is used, only

two sensors can be operated on the HART input (HART addr. 1 … 2).

If HART addr. 3 is used and a current is detected on the 4 … 20 mA

input, a failure message is triggered.
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 T62 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 T62 in Ex version, the passive input is not available

for approval/technical reasons.
