The CN9000A Series has been designed to be as immune as
possible to electrical interference. However, electrical noise
suppression may be required in some applications, particularly if
the output of the controller is firing a contactor or coil. A noise
suppression kit is available for use with 115VAC, OMEGA part
no. 1821-101 (consists of an RC network or metal oxide varistor
(MOV)).
