Note. The diode and zener diode are for the absorption of coil surge. (The coil does not have a polarity.) The opening/closing part does not have a polarity. **3** **PCB Power Relay** ## G5PZ-X ## ■ **Precautions** ## ● **Please refer to “PCB Relays Common Precautions” for correct use.** ## Warning As this relay is a high-voltage and high-current type, there is a risk of abnormal heat generation, smoke generation or fire if you use the relay with a contact voltage, current, or for a number of times beyond the specified range. Use only within the specified ranges. **==> picture [37 x 33] intentionally omitted <==** - The coil has no polarity. Connect the diodes in the reverse polarity of the voltage applied to the coil. - The recommended zener voltage of the zener diode is one to three times of the coil rated voltage. **==> picture [120 x 25] intentionally omitted <==** **----- Start of picture text -----**

## Correct Use ## ● **Handling** This product has a flux-resistant protection structure. Therefore, do not perform immersible cleaning. ## ● **Coil Voltage Reduction (Holding Voltage) after Relay Operation** - If the coil voltage is reduced to the holding voltage after relay operation, first apply the rated voltage to the coil for at least 100 ms, as shown below. - G 5 • A voltage of at least 50% of the rated voltage is required for P the coil holding voltage. Do not allow voltage fluctuations to Z cause the coil holding voltage to fall below this level. - X **[I]** **==> picture [244 x 120] intentionally omitted <==** **----- Start of picture text -----**

- The coil resistance was measured at a coil temperature of 23°C with tolerances of ± 10%. ## ● **Connection of Diodes to the Operating Coil** - Connect a diode and zener diode to the relay coil (refer to the following figure). - The diodes are for coil surge absorption. Switching performance may be affected if only a diode is used, so use in combination with a zener diode. ## ● **Relay Service Life** - These relays must be used for high DC voltages. The final failure mode is failure to break the circuit. In a worst-case scenario, burning may extend to surrounding components. Do not use these relays outside of the specified ratings and service life, or for any application other than high DC voltages. Implement safety circuits and other safety measures to minimize the risk in case of the unlikely event of a failure. - The electrical durability of these relays is specified as the number of load switching operations under a resistive load and OMRON-specified standard testing conditions. - The coil drive circuit, ambient environment, switching frequency, or load conditions (e.g., inductive load or capacitor load) may reduce the service life and possibly lead to failure to break. Always confirm the service life in the actual equipment. ## ● **Micro Loads** These power relays are suitable for switching and breaking highcapacity DC. At high-voltage and low-current, breaking characteristics may become unstable. For switching applications at a range between 0.5 A and 2 A, please consult us. ## ● **Installation Intervals** When using a two-contact series connection, ensure an interval of at least 10 mm between the product units. ## ● **Electrical Appliances and Materials Safety Act** The G5PZ-X series does not comply with the Electrical Appliances and Materials Safety Act. Please select our relays carefully in accordance with the application you wish to use the product for. Please check each region's Terms & Conditions by region website. ## **OMRON Corporation** ## **Electronic and Mechanical Components Company** ## **Regional Contact** **Americas Europe** https://www.components.omron.com/ http://components.omron.eu/ **Asia-Pacific China** https://ecb.omron.com.sg/ https://www.ecb.omron.com.cn/ **Korea Japan** https://www.omron-ecb.co.kr/ https://www.omron.co.jp/ecb/ © OMRON Corporation 2021 All Rights Reserved.
