This programmable logic controller uses industrial-grade 32-bit MCU with strong anti-interference and faster speed. Program is written in ladder logic programming language, supports for GX-, GX-work2, supports HMI connection. Support ladder logic programming language programming, downloading and monitoring. Programming port is the port for program upload, download and HMI communication.Program Steps 8000 steps:2 communication port:one RS232 (DB9 serial communication port is FX3u, protocol 38400,7,E,1; one RS485 port(4 kinds of communication protocol can be set through D8120) Input Point X Component X0-X17, DC24 input, low level effectively.X0-5 high-speed counting input portOutput Point Y component Y0-Y17 are transistor output. Y0~Y7 can output 8-channel 100K pulse or 6-channel PWM pulse signal. Maximum current is 3A. Y0-3 are high-speed output port (max. 100k). PWM period is 0-32767US. High-speed port maximum current is 3A. External load common end connects to +24, the other end connects to PLC output port Y.Analog Input 6 channels analog input, 12-bit precision; 3-channel 0~10V+3-channel 0~20mA, read with RD3A. Analog Output 2 channels analog output, 12-bit precision, output voltage:0-10V. Output analog voltage with WR3A . Intermediate Relay M M0-M3071, power-off save range can be setWidely used for fields of printing, metallurgy, food, textile, packaging, home, building materials, plastics, chemicals.Model FX3U-48MRInput Voltage: DC24VStepping Point S S0-1023, power-off save range can be set S0-S1023100Ms Timer T0-T199, accumulative power-off save T184-T19910Ms Timer T200-T249, accumulative power-off save T246-T2491Ms Timer T250-T383, T250-255 is accumulated type16-bit Counter C0-C199, power-off save C100-19932-bit CounterColour:BlackMaterial:plasticSize:20x16x5cmPackage Contents:1x Control boardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
