FAQ

What type of signals does the 51202901-300 support?

The harness is intended for low-voltage control signals or low-power distribution commonly used within DCS controller and I/O assemblies.

Is this harness suitable for field power distribution?

No. It is designed for internal system wiring and signal integrity, not for high-current or high-voltage field power applications.

Can this connector be reused after removal?

While mechanically reusable, Honeywell recommends inspection for connector wear and shielding integrity prior to reinstallation.
