Schneider TAC Xenta 421A versatile universal input and digital output module designed for building automation systems

The TAC Xenta 421A is indeed a versatile module designed for building automation systems. Let me break down the key details for you:

Functionality: The Xenta 421A operates as a standalone LonWorks node, which means it can function independently within a LonWorks network. This flexibility makes it suitable for various applications.

Input Types: You can configure the Xenta 421A for different input types, including:

• 1.8 kohm thermistor

• Digital input (DI) with green indication

• 0-10 VDC

• 0-20 mA

• 10 kohm thermistor

• DI with red indication

• DI with green inverted indication

• DI with red inverted indication

• Scanning Time: The scan time for all inputs is calculated using the formula: scan time = 200 ms × number of inputs used. For example, if you have 3 inputs, the entire module will be scanned every 600 ms.
