Wiring Notes:
•
Refer to Figures 4-21 and 4-22 for Analog Input wiring connections on the
ATMs.
•
Only 4–20 mA signals are accepted.
•
A jumper is required between a channel’s circuit common terminal and “IN
(–)” terminal when interfacing to a loop powered transducer.
•
All analog inputs have an input impedance of 200 Ω .
•
Each 24 Vdc source terminal has an internal 100 mA fuse in series with it
(located on the ATM). To meet CENELEC ratings, power for sensors and
contacts must be supplied either by the 5009 power supplies, or the external
power supply outputs must be rated for 30 Vdc or less and have its outputs
fused with appropriate sized fuses (a maximum current rating of 100/V,
where V is the supply’s rated voltage or 5 A, whichever is less).
•
It is recommended that 0.75 mm² (20 AWG) or larger twisted/ shielded wire
be used between each transducer and ATM.
•
Shields should be connected to earth ground at all intermediate terminal
blocks, as well as terminated at the control terminal block. The exposed wire
length, beyond the shield, should be limited to 25 mm (1”).
•
Do not place shielded wires in the same cable conduit with high-voltage or
large-current-carrying cables.
•
Cable shields must be electrically continuous from the signal source to the
point the signal wire enters the 5009 Analog Termination Module.
•
ATM terminals accept wires from 0.08–2.5 mm² (27–12 AWG).
