Transmitter Supply Unit with Limit Contact Field Circuit Ex i - Series 9162
The transmitter supply unit with limit value contacts is used for intrinsically safe operation of 2- and 3-wires transmitters or for connection to intrinsically safe mA sources. Furthermore, the device gives the opportunity to compare the analogue signal with two adjustable limiting values.
Exceeding the limiting values or falling below them is reported by the contacts.
The transmitter supply unit can be easily parameterised by means of the ISpac Wizard software.
