4.2 HART ® Connections
HART ® connections are made using two standard banana jacks (3/4” center) located at the top end of the
communicator. Refer to the following diagram. Polarity is not a concern for HART ® connections, therefore,
both jack collars are black. Meriam supplies a HART ® lead kit (P/N ZA900529-00014) complete with mini-
grabber connections and a 250 Ω load resistor with each unit.
Consult your transmitter manual for proper connection in hazardous locations.
For non-IS loops that are low load (less than 250 Ω), a 250 Ω resistor may be needed in the loop to insure
reliable HART
® communication. Meriam supplies a 250 Ω load resistor in the form of a standard adaptor
(P/N ZA36821). Refer to the following diagram for connection details.
