CSD Series Current Devices

Code No. LIT-1900454

Issued April 5, 2013

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 and 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

• 12 VAC/VDC and 24 VAC/VDC accessory

command relays

Refer to the CSD Series Current Devices

Product Bulletin (LIT-12011292) for important

product application information.

Features

• dual function — monitors current and motor

start and stop

• 100% solid-state output — has no moving

parts to fail

• polarity insensitive output — provides

easier wiring

• snap-in mounting bracket — simplifies

installation

• small size — fits in tight enclosures
