Honeywell - Digital Input Module FC-SDI-1624

SDI-1624 Safe Digital Input Module

Overview: The SDI-1624 safe digital input module is designed to provide reliable digital input signals for safety-critical applications. It incorporates advanced fail-safe features and self-testing functionalities to ensure continuous monitoring and integrity of the system.

Features:

• Fail-to-Safe Input Stage: In the event of a component failure, the input signal to the processor is de-energized, ensuring the system defaults to a safe condition.
• Self-Test Functions: The remaining logic circuitry undergoes self-tests within the configured Diagnostic Test Interval, continuously monitoring system integrity.
• Diagnostic Tests: Tests include the ability to receive logic level '0' and '1' signals and checking for crosstalk between inputs.
• Current Limited Output: The 24V DC out pin serves as a current-limited output for energizing redundant inputs via a field contact.
