463-4U... Analog Input Module
When the AE 463 is used in a central configurated ER 701-3 with IM 306 please notice:
•
the 705 connecting cable must not longer than 0.5 m
•
it is not allowedto use the AE 463 in the third expansion unit (EU)
6.3.1
Connecting Sensors to the 463 Analog Input Module
Connecting sensors
Sensors are connected to the analog input module by shielded cables with a max. length of 200 m
(650 ft.). If the cables are run separately from power cables, distances of up to 500 m (1650 ft.) are
possible.
Voltage sensors, current sensors, two-wire and four-wire transducers can be connected in any
combination. There are four short-circuit proof terminals on the front connector for two-wire
transducers.
!
Important
When two-wire transducers are used, the common input of these channels must be
connected to L-. This cancels the galvanic isolation between the channels and the
supply voltage L+/L-. ( 10.11.2 )
It must be noted that the module is enabled via the enable lines F+ and F- on the front connector
with a 24 V DC signal.
Installing the front connector
You must execute the following steps to install the front connector on the analog input module:
1.
Unscrew the connector cover.
2.
Hook the front connector into the pivot at the bottom of the module.
3.
Swing the front connector up and in until it engages with the module.
4.
Tighten the screw at the top of the front connector to secure it.
5.
Screw on the connector cover.
