Device Description 17
753-482 2AI 4-20mA 12 Bit S.E. HART
Manual
Version 1.2.0
The operating status of the channels is indicated by a green status LED per
channel.
A red error LED per channel indicates a wire break, a short circuit or that the
signal is outside the measuring range.
The meaning of the LEDs is described in the “Display Elements” section.
The I/O module 753-482 (2AI 4-20mA 12 Bit S.E. HART) receives the 24 V
voltage supply for the field level from an upstream I/O module or from the
fieldbus coupler/controller via blade-formed power jumper contacts. It then
provides these potentials to subsequent I/O modules via spring-formed power
jumper contacts.
Use supply modules for ground (earth)!
The I/O module has no power jumper contacts for receiving and transmitting the
earth potential. Use a supply module when an earth potential is needed for the
subsequent I/O modules.
Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
Avoid short circuit
A short circuit between the "HART+" connectors and ground can destroy the
module. Therefore, make sure that no grounded part of the field device housing
comes into contact with the "HART+" connector, for example, during installation.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
he HART I/O module can be used with all couplers and controllers of the WAGO-
I/O-SYSTEM 750 listed in the following table “Compatibility List”.
