A local thermal sensor (i.e. connected directy to the clock) can be located near the NDC or as part of 

the frame (for extra fee). The precision of the displayed temperature is given by the precision of the 

sensor.

Minutes:Seconds.hundredths of seconds with selectable automatic switching to Hours:Minutes:Seconds 

or a 99-minute mode (MM:SS.hh)

Functions: START, STOP/FREEZE (intermediate time, the measured time runs in the background), 

RESUME, RESET ;

Automatic restart of the stop watch when the maximum displayable time is reached;

Remote control of the stop watch, external contact (with or without galvanic separation) or with a remote 

button in the NDC-net.

Counter

(counting up/down)

Automatic switching of the display format, range: 1 s to 99 days, 23 hours, 59 minutes, 59 seconds;  

COUNT-UP or COUNT-DOWN mode – adjustable limit;

Functions: START, STOP/PAUSE, RESUME, RESET;

Single or repeated run of the counter when the setup limit is reached;

Switchable counter time correction due to a time change (new time setting) or external time 

synchronisation;

Control of the counter via a remote control, an external contact (with or without galvanic separation) or 

a remote button in the NDC-net;

Possibility to switch on either the internal or a remote relay (close contact) when the limit is reached.

Switch clock

(time interval programming)

Programmable 16 intervals of switching on the output relay in a single day;

Setting of the relay switch on period from 0.01 – 99 sec;

Weekly calendar, setting of switch-on days (from Sunday to Saturday).

Data from remote sensors 

(in NDC-net)

Possibility to display data from 2 remote sensors connected to the NDC-net (e.g. external temperature 

sensor, humidity sensor, pressure sensor, ...). It is possible to set on the clock the remote sensors whose 

data will be displayed. If a local thermal sensor is connected, then it is possible to display just one figure 

from a remote sensor.

The clock allows 

alternate display

of the above data, while the user has the possibility to program the 

duration of their displaying in the range 0 ÷ 60s (0 

no data displayed).

Automatic

(depending on ambient light conditions) or 

manual brightness setting

in 15 levels.

2.2 Display

The height of the display elements is 57, 100, 160 or 212 mm (readability up to 23, 40, 70 and 100 m 

respectively). NDC 57/x and NDC 100/x types use superbright 7-segment LED modules. Other LED colours 

are possible by agreement for an extra fee. NDC 160/x and NDC 212/x types use superbright elliptic LEDs to 

ensure their legibility even in direct sunlight (outdoor).

2.3 Synchronisation, precision

Possibility of external time synchronisation by means of synchronisation modules (e.g. GPS receiver). 

Time display precision:

Autonomous time: ±30sec/month (in +20°C ÷ +30°C temperature range);

When an external synchronisation module is connected, the precision is given by the precision of the 

synchronisation.

2.4 Inputs, outputs

RS485 interface with galvanic isolation for the interconnection with other devices in an NDC-net. 

An input for the connection of a local button with or without galvanic separation for controlling the stop 

watch/counter. The maximum length of the local button’s cable is 3 – 5 m (according to the level of 

interference).

An input for the connection of a local thermal sensor (2 m as standard, or up to 5 m max. as per request)

Built-in output relay 2 A/250 VAC, which can be closed for 0.1 s – 99 s in the counter mode when the setup 

limit is reached or as the output of the switch clock.

GPS Time Receiver input.

2.5 Settings

Time setting manual, wireless via an IR controller or automatic, when an external synchronisation module 

is connected.

Manual or automatic LED brightness control based on the external illumination.

Programming and setting of the clock via a wireless IR controller (max. perpendicular distance 15 m):

Time and date setting;

Activation of selected display modes (time, date, temperature, stop watch, counter, remote sensor) –

intervals of alternating data display;

Limit and modes for the counter;

Stop watch format;

Stop watch and counter control;

Enabling/disabling of daylight saving time (DST);

synchronisation;

Manual time setting;

Counter relay switch-on time setting;

Selection of a local or remote sensor 1 in an NDC-net to be displayed;

Selection of a local or remote sensor 2 in an NDC-net to be displayed;

Selection of the remote input in an NDC-net (only the Master clock, see chapter 

2.9 NDC-net 

communication network

below

)

;

Interval of synchronisation with other clocks in the NDC-net (only the Master clock);

Switching clock – times and periods of switching-on the internal relay, weekly calendar.

2.6 Modifications and dimensions 

NDC 57/x, 100/x – frame of the clock is made of high-quality anodised aluminium profiles in a matt platinum 

grey colour with a metallic appearance. Protection class: IP 20. Operation temperature range:    -5°C ÷
