Manual
Version 1.0.2
The meaning of the LEDs is described in the “Display Elements” section.
Ensuring Immunity to Interference
Place a field-side power supply filter (surge) (750-624/020-001) before the HART
I/O module to ensure immunity to interference!
The I/O module 750-482/000-001 (2AI 4-20mA HART NAMUR NE43) receives
the 24 V power supply and 0 V potential for the field level from the upstream
field-side power supply filter (surge) (750-624/020-001) via the power jumper
contacts designed as blade contacts. It then provides the potential to subsequent
I/O modules via power jumper contacts designed as spring 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.
The 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”.
