(pick-up voltage and drop-out voltage values are those when installed in direction a.) 6. when using the ac type, the operate time due to the in-rush phase is 20 ms or more. therefore, it is necessary for you to verify the characteristics for your actual circuit. moreover, the release time for the nc side of the 2a1b type requires the same veri?ation. 7. since the jh relay latching model is po- larized, be sure to follow the instructions in the wiring diagrams when wiring the + and - coils. mistaken wiring will lead to in- correct operation and failures. short the negative side no. 6 and no. 8 set and reset terminals. 8. when using the push-on blocks for the screw terminal type, use crimped termi- nals and tighten the screw-down termi- nals to the torque listed below. m4.5 screw 147 n?m to 166.6 n?m (15 to 17kg?m) m4 screw 117.6 n?m to 137 n?m (12 to 14 kg?m) m3.5 screw 78.4 n?m to 98 n?m (8 to 10kg?m) for cautions for use, see relay technical information (page 11 to 39). jh relay accessories terminal socket instantly attachable to din rail types specifications * don't insert or remove relays while in the energized condition. part no. applicable relays jh1-l2-sf jh1a-l2 jh2-l2-sf jh2a-l2 jh3-sf jh3a and 2a1b jh3-l2-sf jh3a-wl2 types jh1, jh2 jh3 maximum continuous current* 20 a 250 v ac (1a: 30 a 250 v ac) 15 a 250 v ac breakdown voltage 2,000 vrms between terminals insulation resistance more than 1,000 m w between poles heat resistance 150 c 3 c for 1 hour dimensions 1 form a, 2 form a 10.25 .404 8.4 .331 4 .157 60 2.362 22 .866 9 .354 6 8 7 5 1 2 3 4 9 .354 11 .433 16 .630 23 .906 14.4 .567 11 .433 34 1.339 70 2.756 relay mounting diagram 61 2.402 panel cutout 40 1.575 2-dia. 4.2 .165 (2-m4 screw hole) (.157) [notes] the above diagrams show 2 form a 2 coil latching type terminals 2, 3 and 8 excluded for 1 form a 2 coil latching type mm inch
