Page 3: Operating Characteristics
The functions are des cribed in greater d etail in the following paragraphs. OPERATING CHARACTERISTICS The Type IAV54E relay has a s ingle circuit-clos ing contact that closes when the voltage is reduced to s ome predetermined value; thus ,... - Page 4 GEH-1768 The Type IAVS4F relay is s imilar to the Type IAV54E relay, except that it has a longer operating time. The time characteristics are s hown in Figure 3. The Type IAV54H relay is als o s imilar to the Type IAV54F relay, except that it has a much longer operating time than either the Type IAV54E or the Type IAV54F relays .
