Option H – Hart Serial Communications CP-10/CP-11
 |
Provides an interface to devices supporting the Hart protocol. |
Features:
The Hart option board provides a Bell 202 interface to devices supporting the Hart protocol.
Each Hart option board can be used to communicate with up to 15 Hart devices. When communicating with a single Hart device (point to point installation), both analog and digital data can be read. When communicating with multiple Hart devices (multidrop installation) only digital data can be read.
Up to two Hart option boards can be installed on the one RTU allowing up to 2 point to point circuits or 2 multidrop circuits.
If using two separate point to point circuits and reading analog data, the RTU analog input channels must be isolated from each other.
