The Honeywell 51204166-175 Digital Output FTA - (MC-TDOY23). The 240 Vac/125 Vdc relay Digital Output (DO) FTA has 16 independent electromechanical relays for ac or dc power outputs. The + and - output polarity must be strictly observed for each output. Signals from the 51204166-175 FTA are normally considered as power circuits and, therefore, are subject to electrical codes.

CE Compliant and non-CE Compliant FTAs have unique model numbers. CE compliance refers to the adherence to the CE marking requirements, which are a certification standard indicating that a product meets the essential health, safety, and environmental protection requirements defined by European Union (EU) legislation. The CE mark is a key indicator that a product can be legally sold in the European Economic Area (EEA).

There are also conformal coated and non-conformal coated FTAs. Conformal coating is a specially engineered polymeric film-forming product that protects circuit boards, components, and other electronic devices from harmful environmental conditions like moisture, thermal shock, static, vibration, and contamination.

Most standard FTA types are available with either compression-type or screw-type terminal connectors. The number of terminals for both the compression-type and screw-type terminal connector can vary depending on the type of standard FTA.
