Function

Composition

Application
The KFD0-HMS-16 can operate up to
16 analogue transmitters. The slave
KFD0-HMS-16 can only be operated inconjunction with the HART multiplexer
master KFD2-HMM-16 .
The connection between the KFD0HMS-16 and the KFD2-HMM-16 isaccomplished via a 14-pin flat cable.
The slave address is set by means of a
16 position rotary switch.

Subject to reasonable modifications due to technical advances.

The Hart multiplexer slave is suppliedby the HART multiplexer master via a14-pin flat cable. Connection to the flat
cable is performed with IDC connectors
so that the cable can be tapped at anylocation. In this manner, the power
supply and data lines are linked fromone component to the next. Theaddress (≠ 0) is set by means of a 16
position rotary switch. If the master isonly operated with one slave, then theslave address should be set to 1. If
more than one slave is connected to theKFD2-HMM-16, then the addresses areto be assigned in ascending order.
The analogue signals are fed into theKFD0-HMS-16 by means of a 26-pin
flat cable. 16 leads are designated for
the HART signal of the analoguemeasurement circuit (the remaining 10
leads are sent to ground).
The minimum load resistance of theanalogue measurement circuit is
230 Ohm (minimum load resistance per
HART specifications), the maximum
load resistance is 500 Ohm. It is
possible to have load resistances of up
to 1000 Ohm although resistances of
500 Ohm or greater may cause HART
communication faults.
