LEDs
The D8 expansion module has 1 LED per I/O. The LEDs reflect the state of the input.
State Description
No
color
The input or output is off.
Green The output is on.
Amber
(yellow)
The input is on.
Note:
Forcing an input will not affect the state of the LED. Only a physical current that turns on the
input will make the LED red.
Forcing an output will make the LED green, because the output will physically be on
(conducting).
7.2.5.6. Q1 Expansion Module
The Q1 expansion module is one of the expansion modules available for the RMC70. It has one
quadrature input for 5 V differential A and B signals. The Q1 also has a high-speed Reg input
that can be used for homing or registration of the quadrature input. Each RMC70 can support
up to 2 Q1 modules.
The Q1 is typically used for a reference input from a quadrature encoder. Example applications
include providing position a board on a flying cut-off application or the position of a belt on
material handling applications.
One quadrature encoder can typically output its A and B signals to thirty-two (32) RMC70 Q1
modules. See the Q1 Wiring topic for details.
