ELECTRONIC PRESSURE CONTROLLER
FEATURES/BENEFITS
• Versatile compact package that can replace a separate gage, two
switches, and a transmitter in a system saving money, installation time,
and panel space
• Fully programmable to meet simple or complex application needs
APPLICATIONS
• Process control
• Compressor control
DESCRIPTION
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. 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 simple menu structure, two-line
display, and external programming buttons. Weatherproof housing is ideal for a wide variety
of applications with panel mount, ush mount, or pipe mount ability
