The Triconex 3504E, also known as HDDI3504E by Invensys, is a high - density digital input module engineered for safety - critical applications up to SIL 3 and PL e (Cat. 4).

With 64 channels grouped in sets of 8, it offers extensive connectivity. It's highly versatile, compatible with a wide range of input signal types such as dry contacts, 

switches, and sensors. The module guarantees high accuracy, with ± 0.5% precision, and reliable operation even in harsh industrial environments.

Its fault - tolerant design, based on triple modular redundancy (TMR), ensures continuous operation. It provides isolation between channels and the field devices, and also supports Modbus communication for remote monitoring and diagnostics. This makes the 3504E suitable for various safety - critical applications, including emergency shutdown systems, fire and gas detection systems, burner management systems, turbine control systems, and process control systems in industries like oil and gas, chemical, and power generation.

Technical specifications include an input voltage range of 24 VDC or 48 VDC, an input current of 2 mA, a response time of ≤ 2 ms, an MTBF of > 100 years per channel, and a safe failure fraction of > 0.9999.
