Wiring with EZ

MN05013003E150

Timing relays EZ provides 16 timing relays T1 to T16 for use as required.

A timing relay is used to change the switching duration and the

make and break times of a switch contact. The delay times

can be configured between 2 ms and 99 h 59 min. You can

use positive values, values of analog inputs, actual values of

counter relays and timing relays.

You can also use EZ as a multi-function relay in the

application. EZ is more flexible than any hard-wired timing

relay since you can wire all the functions at the push of a

button as well as program additional functions.

You integrate a timing relay into your circuit in the form of a

contact and coil.

Parameter display and parameter set for a timing relay:

The “flash” function starts on EZ500 and EZ700 with the

pulse. If required, the same timing relays can also be used

for retentive data.

T1 to T16 Contact of a timing relay

TT1 to TT16 Enable, timing relay trigger

RT1 to RT16 Reset coil of the timing relay

HT1 to HT16 Stop coil of the timing relay

(H = Stop , S means the Set coil

function)

To prevent unpredictable switching states, use each coil of

a relay once only in the circuit diagram.
