ABB AO815 3BSE052605R1 Analog Output Module

The AO815 Analog Output Module is a versatile component with several features and benefits. Let’s break down the key points:

1. Channels and Diagnostics:

   • It provides 8 unipolar analog output channels.
   • The module performs self-diagnostic checks cyclically.
   • External Channel Error is reported (only on active channels) if the process power supply voltage to the output circuitry is too low or if the output current is less than the set value (greater than 1 mA in open circuit conditions).
   • Internal Channel Error is reported if the output circuit fails to provide the correct current value.
   • Module Error can occur due to Output Transistor Error, Short Circuit, Checksum Error, Internal Power Supply Error, or Watchdog error.

2. HART Pass-Through Functionality:

   • The module supports HART pass-through communication.
   • However, it only allows point-to-point communication.

3. Channel Isolation and Input Security:

   • The module features 8 channels of 4…20 mA output.
   • These channels are isolated from ground in a single group.
   • Analog inputs are short-circuit secured to either ZP (zero potential) or +24 V.
