Honeywell 9782 Series manual Input, Outputs, Relays

Conductivity/Resistivity Analyzer/Controller

Input

Input to the 9782 can be from any Honeywell conductivity cell at distances up to 1500 feet.

Outputs

Optional isolated 0 to 1 V, 0 to 10 V and 4 to 20 mA outputs are available. Use these analog outputs for retransmission of process variables, or for Current Adjusting Type control using an output signal that is directly proportional to the input (see 1.5.3).

Relays

Two 2A SPDT alarm/control relays are standard, with an additional two 3A relays (either general purpose or hermetically sealed) available as an option (see Sub-Section 2.17). These relays can be used to:

∙take advantage of special features such as automatic cleaning of cells

∙control process variables (see 1.5.3)

∙annunciate alarms

More details about use of relays are provided in 1.5.2.
