Series EDA Electronic Pressure Controller 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. Features include zero set, adjustable dampening, menu
lock out, peak and valley indication, removable terminal blocks, adjustable time delay,
and scalable transmitter output.
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
• Test mode function simulates input over the range without pressuring to easily test
switches and transmitter output function
• Fail-safe relay output choices in case of sensor failure, over pressure, high
temperature limit, low temperature limit, or keypad short
• Selectable alternation of set points between the relays for even wear on duplex
pump applications
• Weatherproof housing is ideal for a wide variety of applications with panel mount,
ush mount, or pipe mount ability
APPLICATIONS
• Process control
• Compressor control
• Filter status
• Duct or building static pressure
• Damper and fan control
