ICS TRIPLEX T8846 Speed Monitor Input FTA

The Trusted® Speed Monitor Input Field Termination Assembly (SIFTA) T8846 is a DIN rail assembly. It provides the input field interface for three rotating machine groups when used as part of a Trusted T8442 Triple Modular Redundant (TMR) Speed Monitor system.

T8846 Features:

• Provides all necessary input interfaces for a Trusted T8442 TMR Speed Monitor.

• Nine speed input channels arranged as three groups of three inputs.

• Separate field power inputs for each of the three speed input groups.

• Field power and signal isolation between input groups.

• Versatile input connectivity allows interfacing with:

    Active speed sensors with totem-pole outputs.

   Active speed sensors with open-collector outputs.

   Passive magnetic, inductive speed sensors.

• Standard DIN Rail mounting.

• All fuses can be replaced in situ.

T8846 Assembly:

The T8846 Speed Input Field Termination Assembly (SIFTA) is an integral part of the overall T8442 Speed monitor system. It is DIN rail mounted, containing passive signal conditioning, power distribution and protection components.

Each T8442 Speed Monitor Module hot swap pair requires a single T8846 SIFTA when installed in a Trusted system.

The SIFTA has nine identical speed transducer signal conditioning circuits arranged as three groups of three.

Each of the three groups is a galvanically isolated entity, with its own field power and I/O signal interfaces.

Multiple sensors must be employed for SIL 3 applications.
