The ECA DIN-style Alarm features a solid metal housing that stands up to the continual rigors of process control and factory automation applications. Rugged and reliable, the 4-wire (line-powered) ECA is the low-cost solution when alarm trip outputs are needed to indicate high or low process conditions. 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 contact closure outputs ideal for indicating a high and/or low condition via a bell, buzzer, light or other annunciating device.
