Time relay URM12-T is a device which allows the realization of time functions with a single changeover relay. The controller is equipped with three buttons grouped on the front panel which allows for easy introduction of the setting (time) and the on / off the countdown at any time.

The unit can operate in one of the following modes:

• Attach the relay for a specified period of time. After the preset time has elapsed the relay is disconnected.
• Attach the relay after a set time until it is relieved by pressing.
• Attach the relay after a set time on a given time previously.
• Repeat to attach and release the relay.

Time can be set:

• In the hours and minutes
• In the minutes and seconds
• In the seconds and hundredths of a second

The device can be equipped with auxiliary input for connecting external trigger button / stop timing. On request it is possible to prepare the version with the option to connect devices in a cascade, controlled by the interface, MODBUS ASCII, or individually prepared for implementing the control algorithm
