The ESU-8 is an 8-Channel Digital Timer Unit, designed to provide straightforward accessibility, for virtually any programmable time-switch application. Weekly event switching of 8 independent relay outputs is included, ensuring precise control of devices – namely, timed switching of bells and sounders in various industrial and commercial applications.

Another important thing to note, is that the ESU-8 can be bought as an alternative to the Danfoss 841 and Danfoss 842 Timer Units, or the Randall 841 or Randall 842 – as they were originally branded. However, this IS NOT a Direct Replacement for the Danfoss 841 or Danfoss 842 Timer Units.

Although this is not a direct replacement for the Danfoss 841/842 Timer Units, it can match their channel capacity, providing 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. Above all, the ESU-8 is a sleek yet modern unit, ideally suited for educational applications where scheduled broadcast of tones, messages, alarms or recorded audio files/tracks is required on an ongoing basis.

Please Note: The ESU-8 Timer should only be installed by an electrician or competent maintenance person. For further information, contact our Technical Support team on 0191 414 4241. Alternatively, you can email us at sales@netr.co.uk.
