Chapter 3 Wiring Connections
Allen-Bradley 1492 wiring systems are available for connecting the I/O module
to external I/O. These wiring systems include a pre-wired cable available in four
lengths: 0.5m (1.6 feet), 1.0m (3.3 feet), 2.5m (8.2 feet), 5.0m (16.4 feet). An
Interface Module for connecting external devices is also available. Cables are
equipped with keyed connectors at both ends for proper connections. Interface
modules are DIN rail mountable and are available with or without field side
status indicating LEDs. Stick-on labels are provided with the Interface modules to
identify I/O wiring termination points.
Summary
This chapter covered the input and output wiring connections for the different
analog and discrete Micro800 expansion I/O modules.
