4.8.4 Analogue Input Module 4-20 mA

Note: The Analogue Input Module mA operates in current sink mode only.
Note: Channel wiring is from left to right for terminals on the top and bottom of the module. It is not
possible to move a plug from top to bottom of a module after wiring.
Please ensure correct wiring by system verification tests. See Commissioning, First Time Switch On, and
Maintenance, Testing the Touchpoint Pro System
The Analogue Input Module mA (AIM mA) accepts 4-20 mA current source signals from field devices (the
module operates in current sink mode only).
The module can supply 18-32 Vdc (24 Vdc nominal) to the field devices at a maximum current of 1 A per
channel, with the additional limitation that the total current drawn from the module must not exceed 2 A at
65 °C ambient or 4 A at 55 °C ambient.
