Additional Notes

• Fail-to-Safe Nature: The input stage is designed to de-energize the input signal to the processor in the event of a component failure, ensuring a safe condition in a normally energized system.
• Self-Test Functions: The module's remaining logic circuitry is covered by the system's self-test functions, ensuring the ability to receive logic level '0' and '1' signals and detect crosstalk between inputs.
• Supply Circuitry: The module features two galvanically isolated groups of eight inputs each, allowing for independent power supply groups to support segregation in process units and subunits.
• Common 0 Vdc Connection: The 24 Vdc (internal) and 60 Vdc (external) must share a common 0 Vdc connection.
