DeviceNet Starter Network
Adapter Product (DSNAP)
The DeviceNet Starter Network
Adapter Product (DSNAP) is a front-
mount device that serves as a single
node on DeviceNet, providing commu-
nication capability, control and moni-
toring to Eaton’s Cutler-Hammer
Intelligent Technologies (IT.) Electro-
mechanical Starters, as well as
the S751 Soft Start, as listed in
Tables 18 – 19.
When HAND/OFF/AUTO is required,
the HOA option will allow for the con-
nection of hard wired operators. This
option allows for Hand Control even if
the DSNAP is not connected.
The product greatly increases the func-
tionality of the IT. Electromechanical
Starter and S751 Soft Start with the
addition of enhanced features.
The IT. DSNAP is designed for use with
the same 24V DC power as the starter.
A starter power sensing circuit indi-
cates to the user that the starter does
not have 24V DC power, signaling a
fault or an E-Stop.

Application
In a typical application, the DSNAP
front mounts to an IT. starter or soft
start. The DSNAP connects directly to
DeviceNet, allowing for control and
monitoring of the starter/soft start. A
PC or PLC serves as the central control
and scans the DSNAP for motor con-
trol and monitoring information.
