Electrical safety
EEx ia IIC T4, Ceq=O, Leq=0; the unit can be connected
without further certification into any intrinsically safe loop
with open circuit voltage <60V and input power <1.2W.
EEx d IIC T4; the unit is apparatus-approved to flame proof
(explosionproof) standards, and can be fitted into a similarly
approved housing.
The TP Series protection network
consists of
high-power, solid-state electronics and a gas-lled
discharge
tube capable of diverting 20kA impulses.
The whole unit is encased in an ANSI 316 stainless
steel housing, threaded for the common conduit
entries used on process transmitters. Versions are
available for 1/2” NPT, 20mm ISO, and G1/2”
(BSP 1/2 inch) threaded entries.

Approvals
The TP units are designed for mounting directly into
an unused conduit entry on a process transmitter
housing. Generally, two such entries are provided,
one of which is used for the loop wiring. On the
unused entry, the blanking plug or other closure
device is removed and an appropriately threaded TP
screwed into its place. The transmitter specication
should provide information indicating the required
thread type. TP units can be installed using thread
adaptors if necessary, including certied adaptors in
hazardous area applications.
For applications where two conduit entries are
not provided or where both are used for electrical
connections, TP units can be housed in conventional
conduit hub or junction boxes, provided access
to the loop terminals is possible. Figure 2 shows
connection details for 3 & 4 wire process transmitter.
