Working principle

The YASKAWA JRMSI-B1026 relay, as the core conversion and isolation component of industrial control circuits, works based on the contact on/off control logic driven by electromagnetic induction. This relay is mainly composed of a coil, an iron core, an armature, contacts, and a reaction spring. It is divided into two parts: the control circuit (coil side) and the controlled circuit (contact side), achieving complete electrical isolation. Firstly, when the rated control voltage (DC 24V) is applied to the coil by devices such as PLC and controller, the coil is energized to generate electromagnetic attraction, which attracts the armature to overcome the tension of the reaction spring and move towards the iron core; Subsequently, the armature drives the moving contact (common terminal COM) to move, first disconnecting from the normally closed contact (NC), and then closing with the normally open contact (NO), thereby connecting the high-power equipment power supply of the controlled circuit, achieving equipment startup or state switching; When the coil is powered off, the electromagnetic attraction disappears, and the armature resets under the action of the reaction spring. The moving contact is disconnected from the normally open contact (NO) and reconnected with the normally closed contact (NC). The controlled circuit is powered off and the equipment stops working. The entire work process achieves safe control of small current to large current through electromagnetic signal conversion, while using electrical isolation characteristics to block interference between circuits, ensuring the safe and stable operation of the control system and controlled equipment.

Precautions

-Voltage matching and coil protection: Before installation, it is necessary to confirm that the control voltage is consistent with the rated voltage of the coil (DC 24V). It is strictly prohibited to apply voltage beyond the rated range to prevent the coil from burning out; Suggest connecting fuses in series in the control circuit of the coil to avoid damage to the coil due to overload current; When not in use for a long time, it is necessary to disconnect the control power supply to avoid aging of the coil caused by long-term electrification and extend its service life.

-Safety operation regulations: When wiring, repairing or replacing components, the power must be disconnected first, and touching the terminals while powered on is strictly prohibited to prevent electric shock accidents.

-Correct wiring and contact matching: Strictly distinguish between coil terminals and contact terminals (COM, NO, NC) according to the wiring manual, strictly prohibit misconnection or mixing, and avoid control logic errors or equipment damage; When wiring, ensure that the terminal screws are tightened and the torque is controlled at 5.0 lb inch to prevent loose connections that may cause poor contact or arcing; Select matching wires based on the power of the controlled equipment to avoid wire overload and heating; The controlled load power shall not exceed the rated capacity of the contacts (10A/250V), and if exceeded, it shall be used in conjunction with a contactor to protect the contacts.

-Standardized installation and environmental protection: The installation location should be far away from strong electromagnetic interference equipment such as welding machines and high-power motors to avoid electromagnetic interference causing contact misoperation; When multiple relays are installed side by side, appropriate spacing should be maintained to ensure good heat dissipation; Strictly follow local electrical regulations for installation, avoid sharing installation brackets with high-voltage equipment, and prevent the risk of electric shock or short circuit.

-Professional operation: The parameter setting, system integration, and fault maintenance of modules need to be completed by professional technicians to avoid system failures or equipment damage caused by non professional operations.
