IC200ALG326
Analog Output Module, 13 Bit Current, 8 Channels
Analog output module IC200ALG326 provides eight 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 8 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 terminals.
The module can also be easily set up with a jumper for the outputs to either hold their last
states or default to low end of 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.
