Page 3: Getting Started
To determine the safety ratings and specification of the entire system refer to each component in the system. Before starting to work with the SEA 9521 module please read this docu ment and the software manual carefully. If there are any questions about operating the module or if any term is not understood, please contact the vendor before using the module. -
Page 4: End User License Agreement (Eula)
The reader should consult the vendor if errors are suspected. End User License Agreement (EULA) Before operating the SEA 9521 and the provided software you have to agree to the terms and conditions (EULA). This agreement is part of the software installation procedure. -
Page 5: Safety Guidelines
Safety Guidelines To protect persons against any harm and the module from damage, the operation of the SEA 9521 module is only allowed according to the rules described in this document. Operator Protection Hot or Cold Surface The metallic surface of the module might be... -
Page 6: Safety Critical Applications
Safety Critical Applications The module is not failure tolerant and therefore not suitable for use in safety critical applications. Do not use the module for medical applications or any live sup porting apparatus. Hazardous Locations The module is suitable for use in non hazardous locations only. Keep the module always away from hazardous locations and ex... - Page 7 Make sure that only qualified personnel wires hazardous voltage adhering to local electrical standards. Do not mix hazardous voltage circuits and human-accessible cir cuits on the same module. The module must not be operated in high voltage areas. Hardware Manual...

Page 9: Connecting The Sea 9521
Connecting the SEA 9521 SEA 9521 provides three independent channels for BiSS-C or SSi en coders, as well as a connector for external power supply. Channel Terminals The encoder channel terminals have a M12 female con nector and accept only encoders with M12 male con... - Page 10 It is important to not switch up “+” and “-” lines. BiSS MasterOut (MO+/MO-) and SlaveIn (SLI+/SLI-) lines (as described in the BiSS-C inter face protocol) are not supported by the SEA 9521 module. If encoders with supply voltages greater than 5V are used, they have to be supplied externally.

Page 12: Double Shielding Encoder Cables
(field ground) and the inner shield t0 module ground, you should avoid connecting both shields together (causing unwanted noise). The SEA 9521 encoder connectors are connected via the SEA 9521 casing and the cRIO connector with the NI cRIO casing and earth. In many NI cRIO system, however, ground and earth are internally connected which leads to an unwanted connection between outer and inner shield. -
Page 13: External Power Supply
Fig. 3. Please check the label of the positive power cord and the ground connector. An input voltage range of 7 V DC to 30 V DC is accepted. The SEA 9521 module and any cabling is not protected against lightning strike or any over-voltage above 30 V. -
Page 14: Sleep Mode
Sleep Mode This module supports a low-power sleep mode. In sleep mode typically there is no communication with the module and the power consumption is minimized. The system thermal dissipation may decrease. Refer to the Specifications section for more information about power consumption and thermal dissipation. -
