Phoenix PHOENIX Relay Shanghai Reputation Channel Provider-Shanghai Nianci Machinery Equipment Co., Ltd. - Dedicated to serving youThe Phoenix PHOENIX relay in Germany is a switch device controlled by current. It is an executing device in various automatic control circuits. Relay (English name: relay) is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity (excitation quantity) changes to meet the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automation control circuits, it is actually an "automatic switch" that uses low current to control high current operation. Therefore, it plays a role in automatic regulation, safety protection, and circuit conversion in the circuit.

Detailed introduction of Phoenix PHOENIX safety relay in Germany: 1. Working principle and characteristics of PHOENIX electromagnetic relay. PHOENIX electromagnetic relay is generally composed of iron core, coil, armature, contact spring, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The armature will overcome the pulling force of the return spring and be attracted to the iron core by the electromagnetic force, thereby driving the moving contact of the armature to engage with the stationary contact (normally open contact). When the coil is powered off, the electromagnetic attraction also disappears, and the armature will return to its original position under the reaction force of the spring, releasing the moving contact and the original static contact (normally closed contact). This suction and release achieves the purpose of conduction and disconnection in the circuit.

For the normally open and normally closed contacts of a relay, they can be distinguished as follows: the static contact that is in a disconnected state when the relay coil is not energized is called a normally open contact; A static contact that is in a connected state is called a normally closed contact. 2. The working principle and characteristics of PHOENIX thermal reed relay. PHOENIX thermal reed relay is a new type of thermal switch that uses thermal magnetic materials to detect and control temperature. It consists of a temperature sensing magnetic ring, a constant magnetic ring, a reed switch, a heat-conducting mounting plate, a plastic substrate, and other accessories. Thermal dry spring relay does not require coil excitation, but is driven by the magnetic force generated by the constant magnetic ring to operate the switch. Whether the constant magnetic ring can provide magnetic force to the reed switch is determined by the temperature control characteristics of the temperature sensing magnetic ring. 3. The working principle and characteristics of PHOENIX solid state relay (SSR). PHOENIX solid state relay is a four terminal device with two terminals as input and the other two terminals as output, and an isolation device is used in the middle to achieve electrical isolation between input and output.

The structure of Phoenix PHOENIX relay in Germany: As shown in the figure, A is the electromagnet, B is the armature, C is the spring, D is the moving contact, and E is the stationary contact. The working circuit of a relay can be divided into low-voltage control circuit and high-voltage working circuit. The control circuit consists of electromagnet A, armature B, low-voltage power supply E1, and switch; The working circuit consists of a small light bulb L, a power supply E2, and static and dynamic contacts equivalent to switches. Connect the working circuit. In normal operation, D and E are not connected, and the working circuit is disconnected. Press down the moving contact point with your fingers, and the working circuit between D and E will be connected due to the contact between the moving contact point and the stationary contact point, causing the small light bulb L to light up. Close switch S, the armature is pulled down by the electromagnet, and the moving contact is in contact with both stationary contacts, connecting D and E. At this point, the spring is stretched and the working circuit is observed to be connected, causing the small light bulb L to emit light. Disconnect switch S, the electromagnet loses its magnetism and has no attraction to the armature. The armature returns to its original position under the tension of the spring, the moving contact and the stationary contact separate, the working circuit is cut off, and the small light bulb L does not emit light.

The Phoenix Contac relay from Phoenix, Germany is suitable for overload and phase failure protection of three-phase AC motors in power systems with AC 50Hz, main circuit rated voltage up to 660V, and current up to 630A. It has functions such as phase failure protection, temperature compensation, trip indication, automatic and manual reset, and is used in conjunction with CJ20 series AC contactors to form an electromagnetic starter. PLC-RSC-24DC/21 PLC relay, consisting of a base terminal module PLC-BSC.../21- with screw connectors and a plug-in micro relay with multiple layers of contacts, can be installed on NS 35/7.5 rails, 1PDT, input voltage 12V DC.

PHOENIX safety relays are composed of several relays and circuits, designed to complement each other's abnormal defects and achieve the complete function of correct and low misoperation relays. The lower the error and failure values, the higher the safety factor. Therefore, multiple safety relays need to be designed to protect different levels of machinery, with the main goal of protecting mechanical operators exposed to different levels of danger.
