4.12 Alternating Current Input/Output (AC I/O) Module
Warning
EMC issues restrict the use of the AC I/O module only to devices using
a PM-12 power module. You cannot use the AC I/O module in a device
that uses either a PM-24 or PM-30 power module.
Switchable I/O and
LEDs
The module has one bank of six DIP switches on its daughterboard
(see
Figure 4-31
), which controls the input/output status of each of the
six channels. Placing a switch in the ON position sets the
corresponding channel to output mode. Placing a switch in the OFF
position sets the channel to input mode. Dual-color light-emitting
diodes (LEDs) indicate the current status for each channel. Red means
AC source is being output. Green means the module has detected AC
on an input channel.

AC Discrete Outputs
In output mode, the module provides up to six channels for switching
discrete AC. Each channel uses a solid-state normally open relay rated
at 1.5 Amps. Any AC switched out is directly related to the AC
switched in. Using ROCLINK 800, you can configure the module as
latched, toggled, momentary, or Timed Duration Outputs (TDOs).
Other parameters report the approximate load, over-current
conditions, and AC input status. Discrete outputs can be configured to
either retain the last value on reset or a user-specified fail-safe value.
