Connection Of The Non-I.s; To 20 Ma Analogue Input; To 20 Ma Analogue Output; Connection Of The Discrete In And Output - Endress+Hauser Tank Side Monitor NRF590 Technical Information

Connection of the non-i.s.

4 to 20 mA analogue input

Connection of the non-i.s.

4 to 20 mA analogue output

Connection of the discrete in
and output
16
Depending on the selected fieldbus communication board, a non-i.s. self-powered or loop powered analogue
transmitter can be connected. The analogue signal for the loop powered transmitter can be connected to the
terminals 14 (-) and 15 (+24 V DC). The maximum supply current for the analogue transmitter is limited to
24 mA. The analog signal for a self powered transmitter should be connected to terminals 11 or 12 and 14.

For all field communication boards except the Modbus Option without analog in/output, a
non-i.s. 4.. .20mA output is available. Via Software settings, this analogue output can be connected to any
parameter in the Tank Side Monitor. The analogue output is available between terminals
13 (+) and 12 (-). From SW 02.01.xx onwards, an additional HART signal is available at terminal 13.
The Tank Side Monitor can be equipped with up to 2 discrete I/O modules. These modules can be used for
interfacing to non-i.s. discrete in- or outputs. Input and output voltage and current ranges depend on the type
of selected module installed in the relevant I/O slot. Terminals 4 and 5 correspond to discrete I/O slot A,
terminals 6 and 7 correspond to discrete I/O slot B. For details on available I/O modules, → ä 30.
