AOT-150
AOT-150
Current Out
The AOT-150 block interfaces high level analog output signals.
It supports 16 nonisolated output channels that operate in
current mode (4 to 20 milliamperes). Special output circuitry
allows this block to support redundant I/O electronics.

NOTES :
1. All specification values are maximums unless stated otherwise.
2. Maximum error includes effects of nonlinearity, repeatability, hysteresis, noise, and quantization error.
3. This is the rate at which the block reads and updates values. The rate at which the values are actually read and become avail-
able to the system depends on the scan cycle of the controller.
