140AVO02000 Quantum I/O Analog Voltage Out Module
Overview The Analog Out 4 Channel module outputs voltages in mixed modes and levels.
These are selected using jumpers on the field-wiring connector.
Specifications The following table shows the specifications for the AVO02000 Analog Out 4
channel module.
Specifications
Number of Channels 4
LEDs Active
1 ... 4 (Green) - Indicates module outputs switched on
NOTE: When the green channel status LEDs are off, the
module is not generating outputs, however, an output may still
be present if the master override signal is used.
Required Addressing 4 words out
