16. DUAL RELAY OPERATION
Dual AC/DC solid state relays rated 120 mA are standard for alarm or setpoint control and are
independently set up via the “Relay Alarms” tab of Instrument Setup Software. For online help
with any data entry field, press the F1 key.
• Setpoint. The number to which the current reading is compared if deviation is set to zero. The
reading is the count in engineering units that is transmitted digitally and is also used for analog
output. For example, if the transmitted reading is in gallons/minute, the setpoint will be
referenced to that reading, not to the raw pulse rate sent from a turbine flow meter.
