Working Principle:
The KJ2201X1-JA1 provides the physical terminal interface between field devices and the SLS1508 logic solver in a redundant safety system configuration. It routes sensor signals to the logic solver for safety evaluation and distributes safety output commands to field actuators. The redundant configuration ensures that a single point of failure does not compromise the safety function.
Installation Requirements:
- Install the terminal block in the designated SLS1508 redundant configuration slot
- Connect sensor and actuator wiring to the appropriate terminals
- Connect the RS-485 communication interface to the control network
- Ensure proper 24 VDC power supply connection
- Verify redundant configuration through the DeltaV SIS engineering tools
Usage Precautions:
- Follow all safety system installation and commissioning procedures
- Verify redundant configuration is properly established before commissioning
- Do not disassemble the module as it contains no user-serviceable parts
- Perform regular functional proof-tests as required by the safety integrity level
- Ensure proper grounding and shielding of field wiring
