HONEYWELL SDOL-0424 24 VDC output module

Description

If the SDOL-0424 input signal is identified as inconsistent through comparison, the system will switch to the safe state of the affected input and indicate this through the system flag. The fault response “system shutdown, process group shutdown, or alarm” should be programmed.

Faults in redundant central parts which are detected and localised by the self-tests result in single-central part operation for a limited time period. The mode of operation; single or redundant does not influence the coverage of the self-tests. The self-test interval is not extended for singlecentral part operation. The self-test interval shall be less than the fault tolerance period of the process (PST). The fail-to-danger-rate of an application including sensors and positioners at the controller’s ascertained MTBF figures and fault coverage rates are not significantly increased by single-channel operation for a limited period.

This period has to be defined by the manufacturers PFD calculation for a specific system The calculated maximum duration for single-central part operation depends on the specific process concerned and must be specified individually for each application. On the FSC system, this is specified by means of the system parameter “Interval time between faults”.
