Transmitter Supply Unit with Limit Values
Series 9162
4
Function and device design
4.1
Function
Application range
The transmitter supply unit with limiting values is used for operation of 2- and 3-wire
transmitters or for connection to mA sources. It is suitable for use in Zone 2, Zone 22
or in the safe area.
The device type 9162/13-11-14 is solely used for operation of intrinsically safe
transmitters or for connection of intrinsically safe mA sources.
In contrast, the device type 9162/13-11-64 can either be used for intrinsically safe
and for non-intrinsically safe transmitters or mA sources.
Mode of operation
The 2- and 3-wire transmitters are supplied with auxiliary power by the transmitter supply
unit. Two limiting values can be defined with which the analog input signal is compared.
Exceeding or falling below the limiting values controls the electrical contacts.
The device can transmit a superimposed HART communication signal bidirectionally.
The parameters of the device can be adjusted using the ISpac Wizard software.
