The CLKTCD18 was the 18-inch large version in the retired CLKTCD range: a timecode-driven clock (IRIG-B/SMPTE and EBU) for very large spaces such as broadcast foyers or large control rooms. For new installations at this scale, Daylight bv points to the TCDS86 (18 cm digits, 6-digit) as the logical current replacement.
Standard Features
- Syncs to SMPTE, EBU and IRIG-B time codes
- Complete flexibility in daylight saving time and time zone configurations
- Front indicator light provides synchronization status
- Microprocessor-controlled stepper motor with sweeping second hand for quiet operation
- Battery-backed real time clock chip in case of loss of syncronization or power
Time Code Inputs
- SMPTE (30/25/25 fps - non-drop frame only) to Leitch Date Encoding Standard
- IRIG-B pulse width coded (unmodulated) DC, IEEE 1344 standard
- IRIG-B(1) 1 kHz Amplitude Modulated, IEEE 1344 standard

Frequently asked questions
Is the CLKTCD18 still available?
No, retired. For very large timecode-driven displays, look at the TCDS84 (18 cm 4-digit) or TCDS86 (18 cm 6-digit), depending on whether you want to show hours-minutes or hours-minutes-seconds.
How does the TCDS86 physically differ from a CLKTCD18?
Different case shape and mounting bracket. An installation rebuild may be needed if the old mounting position is reused. Request a site survey from Daylight bv for exact mapping.
Do I keep the warranty on replacement?
A new TCDS86 receives a fresh full 5-year limited warranty from delivery date via Daylight bv.
Why order from Daylight bv rather than directly from Masterclock?
Daylight bv has been the authorised Masterclock distributor since 2014. You get invoicing in EUR with Belgian VAT, local support in Dutch, French or English, on-site service by prior arrangement and no complications with customs or US imports.
