CSD Series Current Devices
Code No. LIT
Issued August 12, 2008
Description
The Current Switch Device (CSD) Series of
digital output current switches are
non-intrusive devices designed to detect
current flowing through a cable or wire. A
cost-effective solution for monitoring on and
off status or proof of operation, these units are
ideal for monitoring very small current loads
on motors driving fans, blowers, pumps,
heating coils, and lighting.
The CSD models with command relays not
only monitor the current flowing through the
cable but also facilitate the start and stopping
of the motor.
These units also provide a universal
solid-state output and do not require a power
supply. Completely self-powered, these units
draw their power from current induced from
the cable or line being monitored.
CSD Series Current Devices are available in
the following types:
?solid core, setpoint fixed
?solid core, setpoint adjustable
?solid core with command relay,
setpoint adjustable
?split core, setpoint fixed
?split core, setpoint adjustable
?split core with command relay,
setpoint fixed
?split core with command relay,
setpoint adjustable
Refer to the CSD Series Current Devices
Product Bulletin (LIT) for important
product application information.
