Remote I/O
The Remote I/O (RIO) interface allows the 1394 to communicate
with Allen-Bradley position controllers or other RIO devices. Two
identical connectors (CHAN A/P3 and CHAN B/P4) are provided at
the top of the Motion Drive Module. A three-pin connector is used for
the interface. Refer to the Installation Guidelines for the Twinaxial
Cable (publication 92-D1770-BCO) for more information.

Remote I/O Connections
Flex I/O
Flex I/O provides general purpose discrete inputs, discrete outputs,
analog inputs and analog outputs (J2). The Flex I/O Module is
connected to the 1394 with a 4100-CCF1 (maximum cable length is
305 mm (12 in.) or 4100-CCF3 cable (maximum cable length is
0.91m (3 ft). Up to eight modules of the following types can be
connected in any order.
• 1794-IB16 16 Discrete Inputs (24V DC)
• 1794-OB16 16 Discrete Outputs (24V DC)
• 1794-IE8 8 Analog Inputs
• 1794-OE4 4 Analog Outputs
• 1794-IA8 8 115AC Discrete Inputs
• 1794-OA8 8 115V AC Outputs
• 1794-IE 4XOE 2 Analog combination module
• 1794-IB10XOB6 Discrete combination module
• 1794-OW8 Relay output module
• 1794-IF4I Isolated analog input module
• 1794-OB16P Discrete output (protected)
A 1794-ASB adapter is not required. Use a 4100-CCF1 or 4100-
CCF3 cable to connect the 1394 to Flex I/O modules.
