Two set point, two SPDT relay for on/off control
Reliable power supply
from 85 to 250 V AC/DC withstands voltage fluctuations
Two separately
adjustable hysteresis bands prevents rapid contact switching at either
set point
Selectable symmetrical
mode operation eliminates electrical noise
Two-point pH
calibration; offset ORP and temperature calibration
4-20 mA output for
remote monitoring or hard copy recording
Two level password
protection for calibration and setup parameters
Toggle between pH (or
mV) and temperature display
Removable terminal
strips offer quick and easy connections
Battery back-up of
memory maintains set-up if power fails
These sturdy, compact controllers withstand voltage fluctuations from
85 to 250V AC/DC! They are ideal for installation were electrical
fluctuations are common, or install them in series throughout areas of
differing electrical conditions.
Advanced setup mode lets you set relay values, select pH or ORP
control, select manual or automatic temperature compensation, and more.
It also lets you view electrode slope and offset, and previous
calibration points.
The 1/8 DIN housing is ready to install in standard panels and NEMA
rated boxes. Includes mounting hardware; accepts electrodes with BNC
connectors and 100 Pt RTD ATC elements.
