Honeywell 1010121 Fail-Safe Digital Input Module
Honeywell 1010121 Fail-Safe Digital Input Module.pdf
Product Details:
The fail-safe digital input module 10101/2/1 has sixteen 24 Vdc digital input channels. The input stage of the module is of a 'fail-to-safe' nature. This means that a component failure results in a de-energized input signal to the processor, which is the safe condition in a normally energized system.
The remaining logic circuitry on the module is completely covered by the self-test functions of the system. Within the configured process safety time, the modules are tested for:
• ability to receive logic level '0' signals,
• ability to receive logic level '1' signals, and
• crosstalk between inputs.
