• Terminals - Screw
• Size C - 18 inches (462 mm)

The 24 Vdc Digital Input (DI) FTA (51304441-275) accommodate up to 32 switch or proximity detector inputs from a hazardous area, isolate the signal, and presents them to the FTA's associated 24 Vdc Digital Input FTA in the safe area. The 120 Vac Digital Input (DI) FTA accommodates 32 individually isolated ac inputs.

The 240 Vac Digital Input (DI) FTA is similar to the 120 Vac Digital Input FTA, except it accommodates a higher operating voltage, a lower sense current, and the inputs of all 240 Vac DI FTA models are arranged in groups of eight channels, each with a common return for the group.

Digital Input (DI) Field Termination Assemblies are CE Compliant, while others are not CE Compliant. The CE Compliant assemblies are generally identified by a part number tab number that ends in '25' or '75.' They do not have a unique model number.

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.
