Schneider Electric

“Zelio Logic” smart relay

Functions

The Zelio Logic smart relay comprises

- 8 or 10 Time delay function blocks, each with 8 choices of parametering,

- 8 or 10 Counter function blocks,

- 4 Clock function blocks, each comprising 4 channels.

- 8 Analogue function blocks, each with 7 choices of comparator parametering,

- 4 or 6 text function blocks (see Zelio Soft software page).

Time delay function block

: time delay control input

When inputting data to the

time delay

function block TT1, a window auto-

matically opens for the inputting of

the various parameters.

: time delay reset to zero

: time delay output

a : Zelio symbol/type of time delay

s : time base

t 00.00 : time delay value

: locking of time delay value

Depending on the smart relay reference, the time elapsed can be saved in the event of a power failure (remanence)

Counter function block

: counting input

: counter reset to zero

In the first programming line, each

pulse at input I1 increments or dec-

rements the counter C1.

Input I2 determines the counting

direction, either up or down.

: counter output

: up/down counter selection

p : preset value

: locking of preset counter value

Depending on the smart relay reference, the number of pulses already counted can be saved in the event of a power

failure (remanence)

Clock function block

: clock block output

ABCD : time zones

MO 14 : 32 : current date and time

MO –>TH : first day/last day

ON : start time

OFF: off time

: locking of time zones

The insertion of the clock block will

enable output Q1 to change state in

accordance with the preset time

zones.

Programming example with 2 time zones

Channel A time zone

From Monday to Friday, the active

time zone will be from 8 : 00 (ON)

until 21 : 00 (OFF).

Channel B time zone

For Saturday and Sunday, the active

time zone will be from 9 : 00 (ON)

until 12 : 00 (OFF).

Analogue function block

A4 : analogue block output

The analogue function block controls

output Q 4 according to the result of

the comparison.

Ref : reference voltage

≤ Ref : type of operation available

: locking of analogue block reference

value

In this example, output Q 4 changes

state when the value of the analogue

input IC is greater than the 6.4 V

reference voltage.
