IC200ALG328
Analog Output Module, 13 Bit Current, 12 Channels
Analog output module IC200ALG328 provides twelve 4mA to 20mA analog
current-sourcing outputs. Including a modest amount of overrange current,
approximately 20.38mA of output current per channel is available to drive output
loads.

An external source of DC power is required for the outputs.
Intelligent processing for this module is performed by the CPU or NIU. The
module receives 12 words of analog output data.
LED Indicators
The green FLD PWR LED indicates the presence of user-side power for the
analog field-side circuits.
The green OK LED is ON when backplane power is present to the module.
Diagnostics
The module reports a Loss of User Side Power fault for field-side circuits.
Configuration Parameters
The module can be configured for either the 4-20 mA or 0-20 mA output current
range by installing a jumper wire on the field terminal strip.
The module can also be easily set up with a jumper for the outputs to either hold
their last states or default to the low end of their range if backplane power or
communications are interrupted or the PLC is stopped. External user power
must remain uninterrupted.
Outputs remain in their default or last state until the module receives different
output data from the backplane, or until field power is removed.
