The UTR features a number of timing modes that are easily selectable with a mode switch, and its timing periods are set using easy to understand rotary switches.

• Multiple LED indicators for status
• Convenient screw terminal block connections for relay, trigger, and power supply connections
• On-board +5 volt power supply including screw terminal connection for external circuitry
• Unregulated power supply voltage available at screw terminals for powering multiple boards

Setting the timing mode:
The timing mode is set with the Mode switch SW5, which contains eight individual rocker or slide switches. For rocker style switches, the switch is on, or selected, when the switch is rocked forward (down on the far side). For slide switches, the switch is on when the switch is moved forward (toward the inside of the board). Only one switch should be on at a time.

Modes 1, 2, and 3:
In modes 1, 2, and 3 switches SW1 and SW2 set the "coarse" timing portion of the relay-on time and SW3 and SW4 set the "fine" timing portion. The timer will wait to be triggered and then turn on the relay. When the relay-on time has elapsed the relay will be turned off and the timer will again wait to be triggered.

Modes 4, 5, and 6:
In modes 4, 5, and 6, switches SW1-SW2 set the relay-on time and SW3-SW4 set the relay-off time. The relay will be turned on and the timing period will begin as soon as power is applied. When the relay-on time period has elapsed the relay will be turned off and the relay-off time period will begin. When the relay-off time period has elapsed, the on-off cycles will repeat automatically.

Setting the timing period(s):
The timing periods are set by using pairs of rotary switches. Depending on the mode selected, the pair of switches may represent hours, minutes, seconds, or hundredths of a second. The shaft of the switches can be easily rotated by hand and also has a slot on the top for a small straight blade screwdriver as well. The slot running down the side of the shaft is the indicator for which number the switch is pointing toward.

Status LED's:
The UTR contains three LED's which indicate the status of timing periods and modes. The green LED is on when the relay-on time period is active. The red LED is on when the relay-off time period is active. The red LED also flashes quickly if the mode switch is not set to a valid mode. In modes 1, 2, and 3 the yellow LED is on when the timer is waiting to be triggered, and in all modes it flashes on and off once per second when either timing period is active.

Triggering the timer:
The UTR can be triggered in one of two ways, by momentarily pressing the small on-board pushbutton switch labeled TRIG, or by connecting a circuit or switch to the trigger input (TRIG) signal that brings the signal to ground momentarily. The trigger input signal can be operated by any number of signals that cause a low-going pulse at the trigger input signal, including the trigger output signal (TO) of another UTR board. Once the timer has been triggered it will no longer respond to any other trigger signals until the time periods have elapsed.

Trigger out signal (TO):
The trigger out (TO) signal is logic level signal that is normally high and goes low (pulses) for 1/10th second (100 milliseconds) at the end of a complete timing cycle. For modes 1, 2, and 3 this is the relay-on time, and for modes 4, 5, and 6, this is the relay-on time and the relay-off time combined. (If the timing cycle is less than 1/10th second the trigger out signal will of course never have the chance to return high after the first high to low transition.) In modes 4, 5, and 6 the next timing cycle will not wait for the 1/10th second pulse to complete but will start immediately.

However, the UTR does not incorporate a "real-time" clock. For timing periods that are very long, for example, on-off cycles that are set for a 24 hour period, the slight errors in timing will eventually accumulate and be noticeable. For long term accuracy in such an application, a timer with a line powered synchronous AC motor may provide better results.
