SUMMIT 8800 FIELD DEVICE CONNECTION 06
6. Connecting To Field Devices
This chapter details connectivity to the commonly available field instruments that can be con-
nected to the SUMMIT 8800. The following connections are generic, not specific to any brand or
manufacturer. For detailed connections, please refer to the instruments manufacturer installa-
tion manual.
6 .1 Transmitters & Transducers
Typically these devices will be used for temperature, pressure, density.
6 .1 .1 HART Transmitter Input Connections
The HART transmitters are connected in parallel as a multidrop system and each transmitter
must have a unique address.
It is essential that the transmitters have their address programmed and the burst mode opera-
tion turned off before they are connected to the SUMMIT 8800. All transmitters on the same
HART Loop must be assigned different short addresses. It is recommended that the pressure
transmitter be programmed with a short address of 01 and the temperature transmitter with a
short address of 02.
Refer to the transmitter operating manual for their programming procedures.
A typical method of connecting transmitters is given in the figure below and the terminal pin
designations refer to the connections of the I/O board used.
