RH2L SeriesLatch Relays Midget Power Latch Relays DPDT — 10A contact capacity The RH2L series latch relays have a self-holding function by residual magnetism generated by a special magnetic mate- rial. The large 10A contact capacity equivalent to the RH and RR series is provided in a miniature relay package as small as the IDEC’s RH3 type. • With a mechanical operation indicator to show the set/reset status. • Power saving operation by pulse inputs eliminates the need of continuous control voltage. RH2LB-U RH2LV2-U (Plug-in Terminal) (PC Board Terminal) • Available with plug-in or PC board mount terminals. • All basic types are recognized by UL and certified by CSA.

When two or more RH2L relays are mounted in a row, sep- arate the relays by 6 mm or more. 4. Do not energize the set and reset coils at the same time. 5. Because of the polarity of the coil, connect the DC input Internal Connection (Bottom View) voltage to correct terminals of the DC coil type. 1 2 4 5 6 8 9( – ) 10 (+)12 SET 13( – ) (+)14 RESET Dimensions • • • • RH2LB (Plug-in Terminal) Total length from panel surface including relay socket SH3B-05A: 61.5 (63.5) max., SH3B-51: 39.6 (41.6) max.
