Furthermore, the MM4P-JD and MM4XP-JD satisfy the ratings of multi-contact relays provided in JEC-174D (1979) standards for power auxiliary relays. These models work at operation level B specified by JEC-174D (1979) standards and the hot start of the relays is possible after the coils radiate heat. In accordance with JEC-2500 (1987) standards, the coil of each model withstands a 130% DC load or 115% AC load. Note: 1. When ordering, add the rated coil voltage to the model number. Rated coil voltages are given in the coil ratings table. Example: MM2, 6 VAC Rated coil voltage 2. Latching Relays based on the MM Series are also available. Refer to the MMK. 3. Models with built-in varistors (AC operation) are also available in addition to those with built-in diodes. Ask your OMRON repre- sentative for details. 2
