A Rational 8720.155 Wire Harness/Cable channels electrical signals between components for coordinated system function.
The wire harness/cable transfers electrical signals between the control board and the solid state relay so commands are delivered accurately within the equipment. Its dedicated PC board-to-relay construction matters because secure, correctly matched connections support reliable communication, consistent switching and reduced risk of electrical interruption.
The wire harness/cable could need to be replaced if the equipment shows intermittent operation, inconsistent relay response or unexpected loss of control signals during use. Physical signs can include worn insulation, loose or damaged terminals, while environmental signs may include heat exposure, discoloration or brittleness from prolonged operating conditions.
