Features and benefits

• 8 channels of 4 .20 mA

• 1 group of 8 channels isolated from ground

• Analog inputs are short circuit secured to ZP or +24 V

• HART pass-through communication

The AO815 Analog Output Module has 8 unipolar analog output

channels. The module performs self-diagnostic cyclicaly. Module

diagnostics include:

• External Channel Error is reported (only reported on active

channels) if the process power supply that supply voltage to

output circuitry is too low, or the output current is less than the

output set value and the output set value is greater than 1 mA

(open circuit).

• Internal Channel Error is reported if the output circuit can not

give the right current value.

• Module Error is reported in case of Output Transistor Error, Short

Circuit, Checksum Error, Internal Power Supply Error or

Watchdog error.

The module has HART pass-through functionality. Only point to point

communication is supported. The output filter must be enabled on

channels used for HART communication.
