HG Discontinued as of August 31, 2012 20 AMP POWER RELAY HG RELAYS TYPICAL APPLICATIONS Product to be discontinued. FEATURES 1. High-capacity and long life The electrical life of this high capacity is 20A 100,000 operations (250 V AC). It can be used for 1.5kW (3-phase 200 V) motor control. 2. High breakdown voltage Both between contacts, and between contacts and coil, high breakdown voltage is 2,000 V for 1 minute. 3. Easy mounting and wiring The terminal arrangement is apparent at a glance and wiring is easy. Moreover, #250 series tab terminals can be used. 4. Socket and terminal sockets available Lineup includes DIN terminal sockets that enable the use of DIN rails. The pole numbers of the terminal sockets are interchangeable and different terminal sockets can be used in combination. 5. UL/CSA approved HP relays enjoy wide use in various applications, particularly in automation controls and remote controls. Applications include: 1. Industrial machinery For controlling positioning, pressure, and temperature in molding equipment, boilers, pumps, charging pressure equipment, measuring and evaluation equipment, textile machines, etc. 2. Machine tools Control of positioning and directional change in turning machines, lathes, borers, etc. 3. Food processing packing machines Automatic control of packing equipment for milk and seafood, bottling, canning, and packaging 4. Office equipment Control of copiers, time recorders, etc. 5. Coin operate machines Control of food, cigarette, and other vending machines 6. Measuring devices and equipment For repeating installation of control signals and in power amplifiers 7. Generators, transformers and power receiving equipment Functional parts in protective equipment, functional assistance in automatic adjustment equipment, telemeters and other remote monitoring equipment 8. Control of conveyance equipment Control panels for elevators, escalators, and other conveyance equipment, control of all kinds industrial transport equipment such as conveyors. 9. Amusement equipment Control of equipment in amusement parks, etc., control of bowling alley equipment, control of fountains in public parks About Cd-free contacts We have introduced Cadmium free type products to reduce Environmental Hazardous Substances. (The suffix “F” should be added to the part number.) Please replace parts containing Cadmium with Cadmium-free products and evaluate them with your actual application before use because the life of a relay depends on the contact material and load.

The rated current area is15% (60Hz) [AC coils],. 10% (20C) [DC coils] 2. The coil resistance for DC operation is the value measured when the coil temperature is 20C 68F. Compensate 0.4% for every 1C change in temperature. 3. The relay operates in a range of 80% to 110% V of the voltage rating, but ideally, in consideration of temporary voltage fluctuations, it should be operated at the rated voltage. In particular, for AC operation, if the impressed voltage drops to 80% V or more below the rated voltage, humming will occur and a large current will flow leading possibly to coil burnout. 4. As a general rule, only a pure DC voltage should be used for the coil drive. However, a DC power supply that contains ripples has characteristics that differ from pure DC. Therefore, please verify characteristics (operate voltage, release voltage, humming) using the actual circuit that will be used. 2.

Hold-down clip Please use the hold-down clip whenever HG relays will be used in applications where strong vibrating or shock force occurs. 2. Mounting direction There is no restriction on the mounting direction. However, if the mounted relay will be susceptible to strong vibrations or shocks, to avoid influence on switching operations, mount so that the direction of vibration and shock are not in line with the direction of contact switching. (In direction of contact switching operation, resistance to external shock is more than 98 m/s2). Moreover, if the mounted relay is likely to be susceptible to strong vibrations or shocks, be sure to fit the hold-down clip. 3. Environment Avoid use in adverse conditions, such as where there is exposure to harmful gas, or where ambient temperatures are high (more than 40C). 4. Do not insert or remove relays into or out of live circuits. 5. To prevent damage or distortion, when tightening fixing screws, the optimum torque range should be 1.176 to 1.37 N·m (12 to 14 kgf·cm).
