3.12 4-20 mA Isolated Outputs
Channel 1 and Channel 2
(LCD MENU SECTIONS - pH: 4.21 & 4.22, ORP: 5.20 & 5.21,
Conductivity: 6.21 & 6.22, Flow: 7.18 & 7.19)
The Shark Controller has two 4 to
20mA outputs, electrically isolated
from each other and ground. Either
output can source current into a
maximum of 800 ohms.
Channel 1 (the primary output) is
located on the flip out door, terminal
plug P6. Channel 1 is dedicated to
track the process and has fully inde-
pendent and fully adjustable 4 & 20
mA output setpoints. This will enable
the operator to span the output over
the desired range.
Channel 2 (the secondary output) is
located in the enclosure terminal
plug P1. Channel 2 can be selected
to track the process value or tem-
perature and has fully independent
and adjustable 4 & 20 mA output
setpoints.
Both Channel 1 and 2 can be pre-
cisely trimmed through the LCD
menu for precision applications.
The drawing shows the connections
for both outputs.

Note: Leave 4” to 6” slack for all
wires connected to the terminals of
P6. Slack required so that wires do
not interfere with opening or closing
of the front door.
