Weidmuller AI8 - Multi channel signal transmitter - Handbuch (Seite 22)


Power Supply Requirements
Check the power supply against the model number before applying
power to the instrument. AI8 modules must be used with a suitable
mains Power Supply, ratings are as follows:
Voltage Range Nominal Voltage Maximum Power Frequency Fuse value
90-250 V AC - 14 VA 47-63 Hz 500 mA
90-250 V DC* - 14 VA -
20-35 V DC* 24 V DC 14 W (at 24 V DC) - 1 A
*Using a DC power supply that provides this voltage will comply with
the instrument’s UL/CSA listing.
Since the power supply is permanently connected, the building wiring
must be connected through a suitably marked switch or circuit breaker
in close proximity and within easy reach of an operator.
Symbols
The instrument labels use symbols in accordance with IEC61010-1:
- Consult documentation; - Direct Current; - Both direct
and alternating current;
Connections
Strip wires to 7 mm from the ends. Use a suitable ferrule for multi-
stranded wires (do not solder).
Use 1-8 AWG Cu Wire rated for temperatures above 70 °C Only,
tighten to .5 lb-In.
For effective protection from electromagnetic noise, all signal cables
must be shielded, or located on conductive trays or in conduits.
