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: 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. 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.
