An attractive modern designed “duty changeover reIay” in a din rail mounted modular style housing of 1.5 modules width (27mm). A selector switch is provided to select one of four different fixed time ranges from 1 day to 1 month, (there is also a 10 second “circuit proving” setting). This is an ideal simple product to achieve a daily, weekly, fortnightly or monthly duty changeover on pumps, fans and similar equipment especially in the HVAC and pumping industry. A green supply on LED is featured along with a red LED to indicate relay output status. All terminal details and the function information along with the CE mark is clearly marked on the sides of the housing.
Initiated by supply on terminals A1 & A2. Timing commences to energise relay contacts (pause first) and then times to de-energise relay contacts. This cycle continues so long as the supply is connected. The time period on both energisation and de-energisation (T1 & T2) are both fixed. If the supply is removed at any point within the cycle any remaining time will be cancelled and if the relay contacts are energised they will de-energise.
