Compliant with EC requirements:
BS EN61000-6-4 - Generic Emissions Standard – Industrial environment
BS EN61000-6-2 - Generic Standards – Immunity for industrial environments
To meet the EMC specifications, screened cable should be used for installation. The
cable screen should be connected to the internal earth bonding point of the I/P. An
earth strap should also be connected from the external earth bonding point of the
I/P to a common earth point. The cable screen should not be connected at the signal
source when used in IS environments.
Span and Zero and tight shut-off trimpots with 10% adjustment
1/4" NPT supply and output; 1/8" NPT exhaust baffles to allow for captured bleed
1/2" NPT (M20 option); 2 internal screw terminals for 2.5mm
