About the SST-DNP-REL
The SST-DNP-REL is a SST DeviceNet Module created by Reliance Electric for its AutoMax series. This module may have also been sold under the ABB and Baldor Reliance production lines. It has since been discontinued by Reliance and might be a little hard to find. AX Control does still make every attempt to keep the SST-DNP-REL in stock as a refurbished or new surplus part.
The SST-DNP-REL is used to connect an AutoMax PLC system to the DeviceNet. It has the ability to then scan or mimic DeviceNet I/O. This module has an on-board flash that can aid in auto-booting. The DeviceNet protocols are implemented in their entirety on this module. There are two total connections on the module to the DeviceNet. The standard DeviceNet baud rates that are supported on this module are 125, 250 and 500 Kbaud. It is UCMM functional with group 1-3 dynamic connections.
The SST-DNP-REL has a faceplate with many features on it. It has an ON LED indicator that is just above a 7-segment LED labeled Channel 1. It is just above another LED indicator. Below that is a 9-pin RS-232 female connection (to the DeviceNet) that is just above another LED and a terminal strip. Below that is another 7-segment LED labeled Channel 2 above another set of LEDs, another DeviceNet 9-pin RS-232 connection and a terminal strip. There are brackets on the top and bottom of the faceplate that can be used to mount the card to an AutoMax card rack assembly. This card will take up one of the slots on the rack.
