3D Models3 Ch, RS-485 Only
OSENSA’s FTX-310-PWR fiber optic temperature transmitters provide continuous real-time temperature monitoring of switchgear, busbars, and other medium voltage electrical equipment rated up to 38kV.
FTX-310-PWR accepts three optical fiber sensor inputs. It is powered by 12~24VDC and include isolated RS-485 serial connectivity over industry standard Modbus RTU protocol. Multiple transmitters can be connected in series on a standard 35mm DIN rail with power and RS-485 communication supplied by the five-pin T-Bus connector. Optionally included are two programmable 2A relays for over-temperature alarms.
