Electrical connections label

The DPA Series of instruments are often customised specifically for

your application. Check the label on top of the case for the correct

connections.

larm connections

The DPA has a high inbuilt immunity to noise spikes caused by

switching inductive loads like solenoids or relay coils. However, it

is important to use suppression capacitors across inductive loads

to preserve the relay contacts and to reduce the effect of switching

spikes on nearby circuits. The alarm outputs are dual SPDT relay

contacts with built in suppression capacitors fitted across the normally

open and common contacts.

able preparation and installation

For effective protection from electromagnetic noise, all signal cables

must be shielded, or located on conductive trays or in conduits.

se 12-28 AWG Cu Wire rated for temperatures above 70 °C Only,

tighten to 4.5 lb-In. Strip wires to 7 mm from the ends. Use a suitable

ferrule for multistranded wires (do not solder).

nput Signal Cabling

Use suitable twisted pair cable for the input signal connection.
