SD Series Guide to applications and selection

The SD Series of signal protection devices includes models for a full range of applications operating at voltages up to
250V ac. The optional fuse/disconnect package provides both fused protection against fault currents and a convenient
method of isolating field circuitry from protected circuitry without requiring additional disconnect terminals. The standard
fuse (replaceable) is rated 250mA. 50mA fuses are available by special request. Solid links can be used in applications
where only the disconnect feature is required.
This feature is important in applications where a signal protection device is used with a bulk power supply feeding multiple
loops. The individual fuse module prevents a fault or follow on current on one loop disrupting the power supply
to the others. In addition, loops can be removed from the circuit for maintenance or added without requiring additional
disconnect terminals.
The following guide provides application information for the SD series. For technical information, see page 9.

Transmitter and sensor protection

Transmitters and sensors are widely used in highly exposed areas and where lightning damage is common. In many
cases, the ideal solution for 2-wire transmitters or sensors is the TP48, which mounts directly onto the transmitter via
spare conduit entries or a tee fitting. Where these entries are not available or 3-wire devices are used, the compact
design and simple installation of the SD Series makes it an ideal choice for transmitter protection.

The SDs within the junction box should be installed as close as possible to the sensor or transmitter they are protecting,
but no further than one meter away. A bond is required from the general mass of steelwork to the sensor or transmitter
housing, using either a flat short braid or a cable at least 0.16 inch2 (4mm2) cross sectional area. In most instances, this
bond is made automatically by fixing the metallic transmitter housing to the plant structure and ensures the voltage
difference between the signal conductors and the transmitter housing is below the transmitter’s insulation rating.
Please note that the transmitters or sensors are connected to the SD protected equipment terminals, not the field cables.
