The Littelfuse SSAC ERD3228A is a recycling (ON time first) timer for 24 V AC, with isolated DPDT relay contacts rated 10 A resistive at 120/240 V AC and 28 V DC. Its ON and OFF times are equal and set together, adjustable from 0.1 to 10 minutes with its onboard knob.
A recycling timer: upon application of input voltage the output relay energizes for the ON time, then de-energizes for an equal OFF time, and the cycle repeats as long as input voltage is applied. Removing input voltage resets the output and the sequence. For duty cycling, drying, washing, signaling and flashing.
Output: 2C DPDT relay, 10 A resistive at 120/240 V AC and 28 V DC; 1/3 hp at 120/240 V AC, equal on and off times. Repeat accuracy: ±0.5%. Setting accuracy: Factory calibration ±10%; ±2% over temperature and voltage. Reset time: 150 ms. Supply tolerance: -15% / +20% of nominal; 50/60 Hz. Life: 10,000,000 operations mechanical, 1,000,000 electrical.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from -40 to +65 °C and stores from -40 to +85 °C.
