Technical Details of the RS485\4-20mA Connecter (CON066)
SAFE AREA ONLY - Connecting unapproved equipment to the terminals of the instrument
could cause the instrument to become unsafe for use in the hazardous area and will
invalidate the intrinsically safe certification.
The CON066 connecter can be wired as a 4-20mA connector or as a dedicated RS485
connecter. The CON066 is a kit of parts consisting of 2 half shells (1), 2 locating screws (2),
2 fixing screws (3), a ‘D’ type connecter and 4 assorted size clamps (4).
To assemble the CON066 follow the sequence below using the diagram for reference:-

Solder wires to the correct bucket pins of the ‘D’ connecter – see appropriate
section for pinouts,16.1 for “4-20mA” and 16.2 for “RS485”.
2.
Select the appropriate clamps (4) for the cable being used.
3.
Insert 1 half of the clamp (4) in the bottom half shell (1).
4.
Place the ‘D’ connecter in the bottom half shell (1), ensuring the bottom edge of
the connecter is situated in the slot.
5.
Pass the cable over the half clamp (4). Connect the top half of the clamp.
6.
Insert the 2 locating screws (2) ensuring the screw threads protrude through the
‘D’ connecter.
7.
