Franklin 1292S Synchro Transmitter
The Franklin Energy Systems 1292S Synchro Transmitter is an absolute position sensor specifically designed for integration with 1250B and 1250-LTC INCON programmable position monitors. Engineered to provide high-accuracy output signals that strictly correspond to rotary position, this transmitter ensures precision monitoring without zero-position loss after power-down events. It features onboard surge protection to safeguard critical position monitoring infrastructure.
Operating with high stability over variations in time and temperature, the 1292S requires no periodic calibration or re-zeroing. It incorporates a synchro flange for secure mounting and can be successfully retrofitted into legacy Load Tap Changers (LTCs) lacking existing synchros.
Key Specifications and Features
- Compatibility: Designed for use with INCON 1250B and 1250-LTC programmable position monitors
- Protection: Integrated fuse protection and three 150V 14mm metal oxide varistors (MOVs) for active surge protection
- Terminal Type: Phoenix terminal blocks accommodating 28-14 AWG wire termination for reliable circuit board connections
- Sensor Type: Absolute position sensor with fine resolution and excellent signal-to-noise immunity
- Mounting: Synchro flange included for physical installation
- Calibration: Stable operation over time and temperature requiring no re-zeroing
Installation Warning
CRITICAL REQUIREMENT: The 1250 position monitor and the 1292S synchro transmitter MUST be wired to the exact same AC source to function properly.
Frequently Asked Questions
Q: Does the 1292S lose its position data during a power outage?
A: No. The 1292S functions as an absolute position sensor and experiences no zero-position loss after a power-down event.
Q: Can the 1292S be used on older Load Tap Changers (LTCs)?
A: Yes, the 1292S unit can be retrofitted to legacy LTCs that do not currently have existing synchro transmitters installed.
Q: What size wire is supported by the transmitter's terminal blocks?
A: The integrated Phoenix terminal blocks are designed to accept and terminate 28-14 AWG wire.
