IC200ALG331
Analog Output Module, 16 Bit Voltage/Current, 1500VAC Isolation, 4 Channels
Analog output module IC200ALG331 provides four analog outputs. Features include:
Four isolated 4-20mA current output channels
Software configuration, no jumpers or switches
Sixteen bit converter resolution
High accuracy factory calibration
The module provides the following additional software-configurable features:
Per-channel selection of 4-20mA current or +/–10V voltage outputs
Selection of default/hold last state operation
Per-channel selection of default values
Per-channel selection of under-range and over-range diagnostics levels
Per-channel selection of alarm levels
Per-channel scaling
Field re-calibration on command

An external 24V power supply is required for the outputs. In current mode, a separate
power supply may be required for isolated outputs.
The module receives 4 words of analog output data from the system CPU or NIU.
LED Indicators
The green FLD PWR LED indicates the presence of both logic power and field power for
the analog field-side circuits. It does not indicate the presence of other supplies such as
current loop supplies on output points. The absence of either backplane or field power
turns off the FLD PWR LED. Note that this module is the only one that has the OK LED
located before the FLD PWR LED in the A slot.
The OK LED indicates module status:
On green indicates normal operation.
Flashing green indicates boot mode or update
Flashing amber indicates self-diagnostic error.
Off indicates no 3.3V power
