Signal Alarm Trips
An alarm trip accepts an input signal from a monitoring or control instrument, such as a signal transmitter or sensor. When the monitored variable falls outside of a user-set “Trip” (also called “Set”) Point, the alarm trip activates one or more of its relay outputs.

|
Strain Gauge, Bridge, Load Cell Input | The change in resistance of the strain gauge provides an electrical value change that is calibrated to the load placed on the load cell. A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. |
|
DC Input | A DC input has 2 connections for the input signal. These are the signal input and the common connection |
|
AC Input | AC voltage transmitters accept direct voltage inputs. Current models include an external AC current sensor. |
|
Frequency Input | The rate at which something occurs or is repeated over a particular period of time or in a given sample. |
|
Potentiometer Input | A potentiometer is a passive device that provides an adjustable electrical resistance. |
|
RTD Input | RTD input alarm with dual setpoints and two contact closure outputs. The field configurable input and alarm functions offer flexible setpoint capability. |
|
Thermocouple Input | Thermocouple Input alarm provides relay contact closures at a preset temperature input Level |
