ECA - Economy Current and Voltage Alarm
 |
The 4-wire (line-powered) ECA Economy Alarm Trip is the low-cost solution when an alarm trip output is needed to indicate a high or low process condition.
Available models accept current and voltage input from field transmitters, transducers, and other process instruments. When the input falls outside of a pre-set limit (user configurable), the ECA provides a contact closure output ideal for indicating a high and/or low condition via a bell, buzzer, light or other annunciating device.
Single and Dual Alarms - The ECA is offered in both single and dual alarm models. The single alarm provides one output when a trip point is exceeded. The dual alarm accepts one input, and provides two separate trip points per module.
