Features: This programmable logic controller uses industrial-grade 32-bit MCU with strong anti-interference and quicker speed. Premium chip, stable performance, on-line download, on-line monitoring, automatic save when power off. Program is written in ladder logic programming language, supports for GX-Developer, GX-work2. Programming port is the port for program upload, download, test and monitor. It is reusable, stable, easy to learn. The PLC transmission baud rate is 9600. Specifications: Model: FX1N-20mr Working Voltage: DC24（V） Wide Power Supply Voltage: 10-28VDC Baud Rate: 9600 Programming Software: for GX-Developer, for GX-work2. Size: Approx. 86 x 73 x 20mm / 3.4 x 2.9 x 0.7inch Weight: 120G Package Included: 1 x PLC Board Module function: This module is programmable control, can achieve thousands of functions, stable and dependable working performance, built-in watchdog timer circuit, to ensure that the module for a long time to run!!! Some of the common features are shown as follows: Turn on the power supply, the relay 1 is closed for N seconds and then disconnect the relay 2 for N seconds. When the power supply is turned on, the relay 1 is switched off after N seconds, and then the relay 2 is closed for N seconds and then is turned off. The power supply is switched on, the relay 1, 2 have no action, when a signal or trigger button, relay 1 closed off after N seconds; then relay 2 closed off after N seconds, until the next trigger, repeat the same action. Through the signal 1, 2 programming, the control can be achieved on the relay 1 and 2 arbitrarily. When the signal 1 has a signal, the relay 1 is closed, the relay 2 is disconnected; when the signal 2 has a signal, the relay 1 is turned off, and the relay 2 is closed. Can be connected to the NPN sensor signal, the sensor signal programming, to achieve arbitrary control of the relay. When the signal 1 is triggered, the relay 1 is controlled, and when the signal 2 is triggered, the relay 2 is controlled. Turn on the power supply, the control motor is turning N seconds, and then reverse N seconds, followed by the cycle. When the signal 1 has a signal, the motor is controlled to rotate; when the signal 2 has a signal, the motor is reversed. These are just some examples, modules can achieve far more than these functions Input high speed pulse C235, C251 and FX1N compatible. Output relay 1A output, Rated current 5A, can directly drive DC solenoid valve, AC solenoid valve, AC contactor, AC motor, etc,. Precautions for use: The PLC with two programming port. The 232 interface, you can directly use the USB-232 serial port with a computer to download the program directly. The TTL interface. Built-in Analog input AD, corresponding to internal data register D5030.(Not D8030) Built-in Analog output DA, corresponding to internal data register D5101. When the PLC need to connect with the touch screen or text, can be used to connect 232 programming port.
