Dwyer Series EDA Electronic Pressure Controller

Dwyer Series EDA Electronic Pressure Control is an extremely versatile compact package that can replace a separate gage, two switches, and a transmitter in a system saving money, installation time, and panel space. The EDA incorporates two SPDT relays that have the on and off points fully adjustable over the range for control or alarm use. The front face has LED indicators for switch status and a large backlight two-line display showing process value and indication units. Programming is easy with a simple menu structure, two-line display, and external programming buttons. The weatherproof housing is ideal for a wide variety of applications with panel mount, flush-mount, or pipe mount ability. Features include zero sets, adjustable dampening, menu lockout, peak and valley indication, removable terminal blocks, adjustable time delay, and scalable transmitter output.
