FUNCTIONS

■ MOVING AVERAGE OUTPUT

The module samples input signals every H seconds and,

excluding U numbers of highest-value samples and L

numbers of lowest-value samples, outputs proportionally to

the average of the rest [N – (U + L)] of sampled data. When

a new input is sampled after another H seconds, it gives up

the oldest sample and calculates a new average including

the latest sample and outputs proportionally.

When the number of samples to be calculated equals 0 or

less, it outputs an error.

Parameters

H: Sampling cycle

(0.1000 to 100.0000 seconds)

N: Number of samples to be calculated

(1 to 128)

U: Number of highest-value samples to be cut off

(0 to 127)

L: Number of lowest-value samples to be cut off

(0 to 127)

■ DEAD-TIME COMPUTING

The module does not respond to an input signal for a

preset dead-time* duration.

In addition, with adjusting a time constant T, it generates

a first order lag output after the dead-time.

1 + Ts

where

Dead time = H x N (s)

Parameters

H: Sampling cycle (0.1000 to 100.0000 seconds)

N: Numbers of samples to be calculated (1 to 128)

T: Time constant (0.0000 or 0.5000 to 100.0000 seconds)

*Output is refreshed every sampling cycle. The response

time may be delayed by 1 cycle at the maximum.

■ DELAY BUFFER

The module generates a first order lag output.
