General
Holdup Time Software configurable
Note: In the event of a communication loss with the remote processor, this is the
time that output modules will retain their last operating state. Input module data
will be held in the system controlling CPU. After this time, output modules will
assume their predefined time-out states, and inputs will be zeroed by the CPU.
Diagnostics Power Up Power Up and Runtime
Dual Port Memory Check Executive Checksum
LAN Controller Check RAM Address/Data
Bus Current Required (Typical) Single Channel: 600 mA
Dual Channel: 750 mA
Power Dissipation (Typical) Single Channel: 3 W
Dual Channel: 3.8 W
CONNECTIVITY COMPLIANCE
To maintain CE compliance with the European Directive on EMC (89/336/EEC), the
RIO Head module must be connected using quad shielded cable (see the Remote I/O
Cable System Planning and Installation Guide, 890USE10000, V2.0).
Failure to follow this instruction can result in injury or equipment damage.
