Introduction
The TC310 is a simple to program time clock with automatic daylight saving time correction. It offers
6 programmable time zones and can operate from a wide range of input voltages (AC or DC).

45mA (Relay on).
(30mA and 70mA
With Backlit Display)
Output
Changeover Relay contacts.
Contact ratings.
120VAC / 60VDC @ 2A
Settings
6 Time Zones. These can be set to
operate daily, weekdays, weekend
and individual days or switched off.
GMT/BST
Automatic Operation.
Backup
On board battery backup will keep time
and time zone settings for > 100 hours.
Connection
Connection is via a 5 way terminal block.
The 2 terminals marked PWR are to be connected to a power supply either AC or DC in the following
range 9-28V DC or 7-20V AC. Note the voltage input is not polarity conscious. The remaining
3 terminals (NC, C, NO) are voltage free changeover contacts rated at 120VAC/ 60VDC @2A.
Operation
The Display shows the date on the 8 left-hand digits in DD/MM/YY format. The time is displayed on
the next 6 digits in HH:MM format. The colon will flash once every second. The last character on the
right will be blank if the relay is off and # if the relay is on.
Pressing the UP (Black) button replaces the date with the day of week, this returns to the date when
the button is released.
Pressing the DOWN (Grey) button changes the state of the output relay. This will remain in
operation until the next on / off time is reached, or the DOWN button is pressed again.
When one of the preset on times is reached the relay will operate. This will remain on until the off
time is reached or the relay output is overridden by pressing the DOWN button.
