Network Interface: Dual UCN (A/B) 75Ω coaxial connectors (RG‑6/RG‑11)
Redundancy: Supports redundant UCN (A/B channels) for fault tolerance
Diagnostics: On‑board LEDs for link/channel health; remote configuration compatible
Wiring: 75Ω coaxial cable for UCN trunk; shielded connectors required
Hot Swap: Yes (replace NIM modem without system shutdown)
Core Functions
UCN Communication Hub: Connects NIM to TDC3000 controllers, IOPs, and field devices via 1 Mbps UCN.
Legacy Modernization: Replaces outdated PNM, PNM I/O, PNI I/O, and mini‑coax components.
Dual‑Channel Redundancy: A/B UCN channels ensure seamless failover if one link fails.
Signal Conditioning: Amplifies and conditions UCN signals for reliable long‑distance transmission.
Network Diagnostics: Monitors UCN link health; detects cable breaks/signal loss and reports alarms.
Protocol Support: NIM protocol integration with TDC/UCN systems; compatible with Honeywell firmware/tools.
Application Scenarios
TDC3000/TPS DCS: Core modem card for NIM chassis in process industries.
Legacy System Upgrades: Replacement for aging PNM/PNI modems in operational TDC3000 plants.
Remote Communications: Enables UCN connectivity for distributed field equipment.
Redundant Control Networks: Critical loops requiring 100% uptime (chemical, power, pulp & paper).
DCS Maintenance: Spare part for NIM chassis in existing Honeywell installations.
Compatibility Note
System Compatibility: Honeywell TDC3000/TPS (NIM chassis PNI I/O slot only).
Network Compatibility: UCN (Universal Control Network) 1 Mbps protocol.
Replacement: Direct replacement for legacy PNM/PNI modem components.
Firmware: Requires compatible NIM firmware (Rev H+ for EPNI).
