- Safety Instrumented Systems (SIS) discrete output loops
System Compatibility
The 2MLQ-TR2A-CC is designed for integration within Honeywell’s DCS I/O subsystems. Confirm compatibility with your specific system generation before ordering:
- Honeywell TDC 3000 / TPS systems
- Honeywell Experion PKS (with appropriate I/O link)
- Honeywell Safety Manager (SIS applications)
- Honeywell HC900 hybrid controller (verify I/O bus compatibility)
If you are unsure of system compatibility, provide your rack model and controller revision to support@konmask.com for a pre-purchase compatibility check.
Selection Guide
Use the following criteria to confirm the 2MLQ-TR2A-CC is the correct module for your application:
- Step 1 – Confirm output type: Relay contact output required? (vs. transistor/solid-state DO)
- Step 2 – Verify channel count: Match required discrete output channel count to module specification
- Step 3 – Check load voltage/current: Ensure relay contact ratings meet your field device requirements
- Step 4 – Confirm rack/backplane: Verify physical slot and backplane bus compatibility with your DCS rack
- Step 5 – Review SIL requirements: If used in a safety loop, confirm SIL rating meets your SIS design basis
- Step 6 – Check firmware revision: Confirm controller firmware supports this module revision
