750-486 4AI 0/4-20 mA, Ex i 4-Channel Analog Input, 0/4-20 mA,NAMUR NE43, Ex i

PublishTime：2021-01-26

The I/O module 750-486 (4AI 0/4-20 mA, Ex i) measures currents with standardized values of 0 ... 20 mA, 4 ... 20 mA and 3.6 ... 21 mA (Namur NE43) from the field range. Up to 4 currents can be measured. This I/O module connects to 2- and 3-wire sensors. Two-wire sensors are connected via UV and AI and in three-wire technic via UV, AI and 0V. The sensors are basically supplied from the I/O module's field-side power supply.
The I/O module has 4 input channels for field signals. The sensors are connected to the CAGE CLAMP® connectors AI 1 to AI 4. The intrinsically safe supply of the transducer is done with a noninherently short-circuit proof transmitter supply via the connections UV 1 or UV 4. The channels have a common reference potential and a shield connection. The shield connection is fed directly to the carrier rail and contact is made automatically by snapping the module onto the rail.
The assignment of the connections is described in the “Connectors” section.
Connection examples are shown in section “Connect Devices” > ... > “Connection Example(s)”. The Output signal is electrically isolated and will be transmitted with a resolution of 12 bits.
The field voltage and the system voltage are electrically isolated from each other. The operational readiness and the trouble-free local bus communication of the channels are indicated via a green function LED. A red error LED per channel indicates a wire break, a short circuit or that the signal is outside the measuring range. For sensor types 3.6 ..... 21 mA and 4 ... 20 mA, the red error LED also indicates a wire break. The meaning of the LEDs is described in the “Display Elements” section.
Power to the internal electronics is supplied via both the internal data bus and the field supply.
The I/O module 750-486 (4AI 0/4-20 mA, Ex i) 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.
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.
The 750-486 module can be used with the fieldbus couplers and controllers of the WAGO I/O SYSTEM 750 of the specified version or higher listed in the “Compatibility list” table.
