T-GPS Series Time Synchronization Equipment - T-GPS

T-GPS is a time synchronization product that utilizes the Global Positioning Satellite system to provide a very accurate time reference for power system. The output signal formats are configured to match the requirements of all available Disturbance Recorders, Sequence of Event Recorders and SCADA systems. It can be as master and slave with different configuration.

• Power Requirements:
  • DC 190-260V
  • AC 190-260V, 47Hz-63Hz
• Power consumption 5W max.
• Function Acquisition:
  • 90 seconds max typical
  • 90 seconds max with location changes
  • 45 seconds max without location changes
  • 20 seconds max with power instant shut up
• Time Accuracy:

1μs

• Output port features:

We category the following outputs into 7 cards, they are Dry output, TTL output, 485/422 output, serial output, IRIG-B AC output, DCF77 output, Ethernet output :

• Pulse output (PPS/PPM/PPHH/PPH):

Dry output,

TTL output,

422/485 output

• IRIG-B output:

DC output (TTL output and 422/485 output),

AC output

• DCF77 output:

Dry output

• Serial output:

RS232 and RS422/485.

• Ethernet output
• Master/Slave:
  • As master, you should have the following cards:

Power Card,

Signal In Card (Antenna Card), Alarm Card

Some any required cards.

• As slave, you should have the following cards:

Power Card,

Alarm Card,

IRIG-B In Card I

IRIG-B In Card II (as backup)

Any other required card

• Cards:
  • Dry Contact Output Card:

Max. 12 nos.

• Serial Port Output Card:

Max 4. Each one can be set as TXD0, TXD1 and IRIG-B DC signals

• TTL Output Card:

Max. 12 TTL outputs, the output can be Pulse output or IRIG-B output

• 485/422 Output Card:

Max 12 nos, the output can be Pulse output or IRIG-B DC output

• IRIG-B AC Output Card:

Max 12 nos.

• Dry contact DCF77 Output Card:

Max 12 outputs.

• Ethernet Card:

One Ethernet output for each card.

• Environmental:
  • Operating Temperature 0°C to +50°C
  • Storage Temperature -40°C to +50°C
• Dimension:

19'', 2U

Special Note:

T-GPS has 7 blank cards space for the above 6 kinds of cards, but for power consumption reason, the maxim number that it can have for TTL card is 4, for 422/485 card, the maxim number is 3 and IRIG-B card is 4. This is condition for T-GPS acts as Master.

For T-GPS as slave, there will be 6 blank card spaces since it has to have 2 IRIG-B IN cards, and one Signal In (Antenna) card is not necessarily installed.
