DeviceNet Starter Network Adapter Product (DSNAP)

Catalog Number D77B-DSNAP with 54 mm IT. Starter

The DeviceNet Starter Network Adapter Product (DSNAP) is a front- mount device that serves as a single node on DeviceNet, providing communication capability, control and monitoring to Eaton’s Cutler-Hammer Intelligent Technologies (IT.) Electromechanical 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 connection of hard wired operators. This option allows for Hand Control even if the DSNAP is not connected.

The product greatly increases the functionality 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 control and monitoring information.
