Universal Time Delay Relay type NT 10

Features * 4-User configurable operating modes

* Wide timing range

* Easy Setting through DIP switches

* Manual Reset 'Flag' LED indication

* Both signaling duty and trip duty

contacts available

* Micro-controller based design for

high accuracy

Application: The NT 10 relay is intended for use

where high operating requirements are

necessary, such as in protection relay

systems, control equipment, industrial

processes, and control and signal

systems.

The multiple user selectable options

provide flexibility to user, for use in

various applications. The wide timing

range, high timing accuracy and

consistency of operation can replace

any other time relays.

Description: The time delay relay type NT 10 is high

precision, numerical time relay with

builtin electro mechanical output relays

providing- two CO signaling duty

contacts and one NO trip duty contact.

The micro-controller based relay designprovides accurate timing and varied

operating modes. The four operating

modes are: ON Delay, OFF Delay,

Flasher and Interval. The required

timing and operating mode can be set

by adjusting the DIP switches on the

front panel.

The timing function is triggered by

control input depending on the mode

selection. The control input has same

rated voltage as auxiliary voltage andis galvanically isolated.

The four LEDs on the front panel

indicates status of relay. The presence

of healthy auxiliary supply is indicated

by green 'Uaux' LED. The operation of

relay is indicated by red 'TRIP' LED.

The yellow 'Start' LED indicates,'timing' status in 'ON Delay' and 'OFF

Delay' modes. In 'Flasher' and 'Interval'

mode Start LED indicates the status of

control input.

The start LED additionally indicates the

change of mode selection. When mode

setting is changed, yellow 'Start' LED

blinks and the relay does not respond

to the control input till mode setting

change is applied by pressing 'Reset'

push button. The 'IRF' LED indicates the internal

relay fault.

OperationalModes:

The following modes are possible when the relay is energized with auxiliary supply.

ON Delay: In this mode, the timing starts when the control input is applied and after

the set time has elapsed, the delayed output switches to the operate condition

OFF Delay: In this mode, the output immediately switches to operate condition

when applying the control input and in which the timing starts when the control

input is disconnected and the output switches to released condition after set time

has elapsed

Interval: In this mode, the relay switches the output to operate condition for set

time when the control input is applied or removed

Reset PB will not have any

effect in this mode

Flasher: In this mode, the output periodically switches on and off with substantially

identical pulse on time and pulse off time as long as the control input is applied

Reset PB will not have any

effect in this mode
