Each transmitter accepts from three to nine optical fiber sensor inputs. The FTX-910/610/310-PWR+ transmitters are powered by 12~24VDC and include isolated RS485 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. Also included are two programmable 2A relays for over-temperature alarms.

Medium voltage rated fiber optic temperature probes can be installed on switchgear contacts, bus bars, cast resin transformers, motors, and generator windings to provide reliable 24/7 thermal monitoring with noise-free performance.

The probes are constructed from durable, high dielectric strength materials and have been tested to safely operate on equipment rated up to 38 kV (3 phase). They install quickly and can be ordered with optional probe-tip attachments suitable for various applications.
