Time TTM 01
TekTime TTM 01 DATASHEET
A reliable and accurate GPS controlled time
synchronization solution in a small form factor.
Suitable for use with with industrial control and SCADA
equipment, including protection relays and remote
telemetry units.
Electrical isolation on all outputs provides exceptional
noise immunity, making TTM 01 ideal for use in
electrical substations and other harsh environments.
Compact: DIN rail mountable case facilitates ease of
installation.
User friendly: Dedicated USB port and Windows
software, makes customizing and setup a breeze.
Compatible: Supports industry standard protocols
including DCF-77, IRIG-B, and user defined pulses.
Serial port version supports an extensive range of
strings including NMEA (ZDA & RMC), IRIG-J, NTGS.
Complete: TTM 01 is supplied with all necessary
components for installation including a timing-
optimized GPS antenna, and ultra-flexible cable.

Programmability
Customizing TTM 01 is via an
in-built USB port and
graphical Windows based
configuration software. User
adjustable options include:
Timing & Synchronisation
Worldwide daylight savings
configuration using either rule based or fixed date
methods.
Options that allow equipment checks prior to full
installation and adjustable hold-over times to increase
reliability in the case of poor GPS coverage.
Adjustments to compensate for installation parameters
such as delay of GPS signal through antenna cable.
Time Codes and Pulses (TTL or serial TTM-01)

Lightning Protection Kit Option
The antenna lightning protection kit affords additional
protection through the use of an impulse suppressor
installed in the antenna lead-in coax cable. In the event of
a lightning-derived high voltage surge occurring on the
coaxial cable, the impulse suppressor activates, short-
circuiting the cable directly to the protection ground.
Lightning Protection Kit Contents
All components required to install lightning protection are
included in the kit.
