Core Performance Indicators
100‑micron fiber optic compatibility; supports LCN extension; simplex upgrade kit; designed for TDC3000/PKS/TPS systems; stainless steel fiber interface
4-20 mA HART Loop Protocol
Although primarily a fiber‑optic extender, integration within Honeywell process control systems ensures:
FOUNDATION Fieldbus / Profibus PA connectivity maintained through upstream controllers.
Channel‑to‑channel isolation preserved across extended LCN nodes.
Cold junction compensation (CJC) applied in interfaced I/O modules, unaffected by extender operation.
4‑20 mA HART loop protocol signals remain transparent when routed through extended LCN paths.
Frequently Asked Questions (FAQ)
Q: Can the TP‑ZEN100 be installed while the LCN is active? A: No. Fiber optic connections must be isolated before insertion to prevent signal loss or transient errors.
Q: What fiber specification is required? A: The TP‑ZEN100‑100 is optimized for 100‑micron fiber optic cable. Other fiber sizes are not supported.
Q: Is the extender compatible with redundant LCN configurations? A: Yes. It can be deployed in both simplex and redundant LCN architectures, provided fiber routing and controller assignments are correctly configured.
Field Installation Guidelines
Verify fiber optic cleanliness before insertion; contamination can cause attenuation.
Maintain bend radius limits for 100‑micron fiber to prevent signal degradation.
Ensure extender board is mounted near controller racks for minimal fiber routing.
Ground extender chassis to plant earth to reduce EMI coupling.
Confirm LCN node addressing after installation to avoid duplicate assignments.
Perform optical link diagnostics post‑installation to validate signal integrity.
