Analog Output Module, 13 Bit Current, 12 Channels
Jumper Selection
Range Jumper
If no jumper is installed the output current range will be 4 to 20 mA. With a
jumper installed the output current range is 0 to 20 mA. This should only be
changed with field power and backplane power removed. The corresponding
parameter in the hardware configuration must also be adjusted accordingly.
Hold Jumper
If no jumper is installed outputs hold their last states (the last commanded
values from the backplane) if backplane power or communications are
interrupted or the PLC is stopped. With a jumper installed, if such conditions
occur outputs default to 0/4mA. This should only be changed with field power
and backplane power removed. The corresponding parameter in the hardware
configuration must also be adjusted accordingly.
The "Default Low End of Range" value can be either 4mA or 0mA. The default
depends on the PLC status, output current range selected, and whether the
module is controlled by a VersaMax PLC CPU or a Network Interface Unit (NIU)
module. In some cases, the module will output 0mA instead of 4mA, even
when configured for the 4-20mA range as displayed in the following chart.
