Multifunctional impulse switching relay UC. 1+1 normally open contact, potential-free 10A/250V AC, incandescent lamps 2000W. No standby loss. For flush mounting. 45mm long, 45mm wide, 32mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. Universal control voltage 8..230V UC. No constant power supply required, therefore no standby loss. By using bistable relays, there is no coil power loss and no heating as a result, even when switched on. The relay contact can be open or closed when commissioned and synchronizes when first activated. The functions of the second rotary switch are preselected with the ES/ER rotary switch. The clamp functions are selected with ER. You can choose between 10 functions: 2S = impulse switch with 2 normally open contacts. (2R) = switching relay with 2 normally open contacts. WS = impulse switch with 1 normally open contact and 1 normally closed contact. (WR) = switching relay with 1 normally open contact and 1 normally closed contact. SS1 = series switch 1+1 normally open contact with switching sequence 1. (RR) = switching relay (closed-circuit relay) with 2 normally closed contacts. SS2 = series switch 1+1 normally open contact with switching sequence 2. (EW) = switch-on wiping relay with 1 normally open contact and 1 normally closed contact, wiping time 1s. GS = group switch 1+1 normally open contact. (GR) = group relay 1+1 normally open contact. Switching sequence SS1: 0 - contact 1 (1-2) - contact 2 (3-4) - contacts 1+2. Switching sequence SS2: 0 - contact 1 - contacts 1+2 - contact 2. Switching sequence GS: 0 - contact 1 - 0 - contact 2. GR: relay with alternately closing contact. This relay is not suitable for feedback with the switching voltage of a dimmer switch. Only use the relays ESR12DDX-UC, ESR12NP-230V+UC or ESR61NP-230V+UC. The electronics do not have their own power supply and therefore do not consume any power in either contact position. Only during the short control pulse of just 0.2 seconds does the control current flow, which activates the microcontroller, lets it read the last switching state from its non-volatile memory, switches the bistable relay accordingly in the opposite direction and writes the new switching state back into the memory.
