The ESU-8 8 Channel Timer can be used as a ‘direct replacement for the Danfoss 841 and Danfoss 842 timer units’ or the ‘Randall 841 or Randall 842′ (as they were originally branded). Offers straightforward accessibility, and can be easily programmed for virtually any time switch application.

Another key feature of the ESU-8 is its sleek yet modern design, ideal for educational applications where the scheduled broadcast of tones, messages, alarms or recorded audio files/tracks is required on an ongoing basis. Above all, it is a great device for timed switching of bells, sounders, and other devices in industrial and commercial applications.

In essence, the ESU-8 is an undoubtedly versatile solution, which can even be used to control certain domestic devices, such as under floor heating! This Timer Unit has been designed to provide programmed weekly event switching of 8 independent relay outputs – easily matching the Danfoss 841 and 842 channel capacity, and provides NO (Normal Open) or NC (Normal Closed) relay contacts to each of its 8 Relay Outputs, with 10A capability at UK mains voltages or up to 24V DC applications.
