The input relay is used to take signals from external buttons, transfer switches, etc., as well as signals from photoelectric switches, proximity switches, pressure switches, etc. to the PLC. Input current 7mA Input delay time can be set (1~128ms)

First, overcurrent (OC) Overcurrent is the most frequent phenomenon of inverter alarms. 1.1 Phenomenon (1) When restarting, it will trip at a speed. This is a very serious overcurrent phenomenon. The main reasons are: load short circuit, mechanical parts are stuck; inverter module is damaged; motor torque is too small and so on. (2) Jumping […]

Due to the increasing number of applications and the increasing complexity of modern industrial production, the demand for more sophisticated and reliable sensors is increasing. For example, the identification of color detection and color change is more complicated. One of the applications, such as the packaging machine in which the machine is to determine which […]

In order to allow the monitoring center to communicate with multiple GPRS modules at the same time, multiple work sites can be monitored. 3, Bluetooth The Bluetooth system consists of a wireless unit, a link controller, a link manager, and a support unit that provides functions to the host interface. The Bluetooth wireless unit is […]

Analog output vs digital output: This is the first thing to consider. This depends on the interface between your system and the accelerometer. Generally, the voltage and acceleration of the analog output are proportional. For example, 2.5V corresponds to an acceleration of 0g, and 2.6V corresponds to an acceleration of 0.5g. Digital output typically uses […]

Under normal circumstances, the RFID coding system has three standard systems, namely the ISO standard system, the EPC Global standard system and the Ubiquitous ID standard system. The ISO standards in the RFID field can be divided into the following four categories: 1) Technical standards (such as radio frequency identification technology, IC card standards, etc.) […]
