8.3 Configure the mA Input

The mA Input can be used to read temperature or pressure data from an external device. The current value of
the process variable is represented as a mA signal between 4 mA and 20 mA. In SIL installations, the mA Input
must be used to verify the operation of mA Output 1, and cannot be used for temperature or pressure data.
Depending on your purchase order and channel configuration, the transmitter may have zero or one mA
Input. Only Channel D can be configured as an mA Input.

mA Input Assignment defines the type of data that is being sent to the mA Input.
Procedure
1. Set mA Input Assignment to the type of data that is being sent to the mA Input.
Option Description
None (default) No data is received, and the mA Input is disabled.
Pressure The mA Input signal represents pressure data.
Temperature The mA Input signal represents temperature data.
Loop Current The mA Input reads back the signal from the mA Output 1 loop. This setting is
required for SIL compliance. The option is available only when SIL is licensed on the
device.
Calorific Value The amount of heat released during the combustion of a specified amount of a gas.
Measured in units of energy per units of the gas. Energy = calorific value.
2. If you set mA Input Assignment to Pressure or Temperature, ensure that the transmitter and the
external device are using the same measurement units.
