Note: 1. The rated current and coil resistance are measured at a coil temperature of 23qC with tolerances of +15%/–20% for rated currents and r15% for DC coil resistance. 2. Performance characteristic data are measured at a coil temperatures of 23qC. 3. AC coil resistance and impedance are provided as reference values (at 60 Hz). 4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder resistor if required.

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for rated currents and ±15% for DC coil resistance. 2. Performance characteristic data are measured at a coil temperatures of 23°C. 3. AC coil resistance and impedance are provided as reference values (at 60 Hz). 4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder resistor if required.

Safety Precautions Refer to Safety Precautions for All Relays.

Safety Precautions for Correct Use Installation Mount the MK-S with the marking at the bottom.

Handling Check the coil polarity of models with built-in operation indicator (DC operation coil) and wire them correctly .

Test Button Do not use the test button for any purpose other than testing. Be sure not to touch the test button accidentally as this will turn the contacts ON. Before using the test button, confirm that circuits, the load, and any other connected item will operate safely. Check that the test button is released before turning ON relay circuits. If the test button is pulled out too forcefully, it may bypass the momentary testing position and go straight into the locked position. Use an insulated tool when you operate the test button. Models with test buttons or LED indicators fulfill the requirements for reinforced insulation between live parts and the front of cover only when the Relay is in a complete condition, i.e. with the nameplate, nameplate frame, test button, and slider in place. If any of these parts are removed, only the requirements for basic insulation are fulfilled.

Models Conforming to Auxiliary Power Relay Specifications The MM4P-JD and MM4XP-JD satisfy the ratings of auxiliary relays provided in JEC-2500 (1987) standards for power protective relays specified by the Japan Electromechanical Commission. 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 representative for details.

Use a contact current of 0.5 A or less when switching 125 VDC or more. 2.

Safety Precautions Refer to Safety Precautions for All Relays.

■ Connection

■ MMXP

• Use proper crimp terminals or 1.2- to 2-mm-dia. single-conductor wire to connect screw terminals. • Connect loads to DC-switching Relays so that arcs from adjacent terminals will not strike each other. E.g., connect all common terminals to the same polarity. • Screw Terminal Model: Do not bend the coil terminals, otherwise the coil wire may be disconnected. Make sure that the tightening torque applied to each terminal is 0.78 to 1.18 N·m and the insertion force is 49 N for 10 s. • Do not reverse polarity when connecting open DC-switching Relays, including 3- and 4-pole models.

The MMXP has a hole in the Relay case to allow gas to escape. Do not use this Relay in locations subject to excessive dust.

■ Installation

The contact load should be greater than the power consumption of the coil. If it is less than this power consumption or if the Relay is operated very infrequently, the contact can change chemically thus causing unstable operation.

• Do not install the Relays where iron dust can adhere to the contacts or coil. Such dust can prevent the armature from moving freely and inhibit proper electrical contact. • Relays can generate arcs externally. Either install the Relay in a location where a nearby object will not burn or use a covered Relay. • DC-switching Relays contain a permanent magnet in the insulation base. Do not place a magnet or magnetic object near this base. Doing so will reduce the power of the permanent magnet, thus reducing Relay capacity. • Insert PL Back-mounting Sockets from the back of the panel. • To minimize the influence of heat, separate Relays from each other by at least 20 mm for cooling when mounting multiple Relays together. 20 mm min.

Top

MM

MM Mounting orientation

Bottom

• Relays should be mounted with the armature facing down.

■ Wiring When connecting a load to the contact terminals of a model for DC loads, consider the polarity of the contact terminals so that the generated arcs on the adjacent poles will not collide. If the common connections of the Relay are all positive or all negative, no arc collision will occur.

■ Contact Loads

■ Soldering When soldering solder terminals, do not let flux or other foreign matter adhere to contacts or do not let the coil terminals become bent. Also, solder as quickly as possible because excessive heat may damage the coil.

■ Diode Built into Relays A diode is built into the Relays to absorb reverse electromotive force from the relay coil. The diode will be destroyed if a large external surge voltage is applied. If there is a possibility of a large external surge voltage being applied, take suitable measures to absorb the surge.

■ Storage A model for DC loads incorporates a permanent magnetic for arc suppression. Keep floppy disks away from the Relay, otherwise the data on the floppy disk may be damaged.

■ Operating Environment Do not use the Relay in places with flammable gas, otherwise an explosion may result due to an arc generated from the Relay
