Franklin INCON 1250-LTC-4-I-M Programmable LTC Position Monitor
The Franklin INCON® 1250-LTC-4-I-M is an advanced programmable Load Tap Changer (LTC) Position Monitor designed for precise transformer monitoring and grid reliability. It bridges the critical data gap between the LTC and its controller by relaying precise position information and tracking continuous LTC movement, which allows for active predictive maintenance.
Engineered for utility-grade electrical infrastructure, this specific model features a 4-20 mA analog output, comprehensive input isolation, and robust RS-485 MODBUS communication. It calculates absolute position data directly from a Synchro Transmitter and triggers programmable alarms during key operating conditions, ensuring operations teams are proactively alerted to scheduled maintenance needs.
Key Capabilities
- Absolute Position Monitoring: Accurately measures and relays absolute tap position directly from a connected Synchro Transmitter.
- Predictive Maintenance: Tracks physical LTC movement continuously to help operators schedule required service prior to failure.
- Programmable Alarms: Configurable alerts tailored to key operating parameters and environmental thresholds.
- Data Integration: Outfitted with an isolated input, standard RS-485 MODBUS communication, and 4-20 mA analog output for straightforward integration into existing SCADA or facility control systems.
