BLK-100
Blank Block
The BLK-100 block is used to fill empty block positions on a
column. Any empty positions within a column of blocks must
be filled to maintain airflow. Blank blocks are not required,
however, in empty positions at the bottom of a column. The
block supports redundant blank modules.

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.
