Can you have more than one alarm trip?
Alarm Trips with Multiple Relay Outputs A limit alarm trip can have one, two or even four relay outputs. Typically, each relay output can be set to respond to a different trip point. This would include any combination of high or low alarm trips, with different trip point settings for each.
What is the purpose of a limit alarm trip?
This type of alarm trip monitors temperature, pressure, level, flow, position or status variables, and is typically used to warn of unwanted process conditions or to provide emergency shutdown. A limit alarm trip can have one, two or even four relay outputs.

How many relay outputs does an alarm trip have?
This type of alarm trip monitors temperature, pressure, level, flow, position or status variables, and is typically used to warn of unwanted process conditions or to provide emergency shutdown. Alarm Trips with Multiple Relay Outputs. A limit alarm trip can have one, two or even four relay outputs.
When to use trip or high alarm settings?
This would include any combination of high or low alarm trips, with different trip point settings for each. Some alarm trips also offer the option of setting the relay to trip if there is an input fault (such as a broken sensor), or to alert that there is a problem with the alarm trip itself (Figure 4).
If the process signal moves to an undesirable high or low condition, the alarm activates a relay output to warn of trouble, provide on/off control or institute an emergency shutdown.
