Welcome to our store! 1. The PLC supports 2 channels of RS232, one of which is used for writing monitoring programs. 2. Can be used for touch screen communication, extended temperature, pressure, etc. 3. All relays use imported high-quality relays with relay contacts: AC max 5A 250V, DC max 30V 5A. 4. The CPU adopts the imported STM32F103 series, offering extremely fast download speeds, typically within seconds, saving batch processing time. 5. This board is a PLC board; use programming software directly to compile ladder diagrams, write directly to the PLC, and perform online monitoring. Item Type: Industrial Control Board Optional Style: Without base and shell, With base and shell Technical Parameters: Power: DC24V Program Steps: 8000 steps Communication Port: 2 x RS232 (standard 9-pin serial port, FX3u protocol 38400, 7, E, 1), 1 x RS485 Input Point X Component: X0-X17, DC24 input, low level active. X0-5 are high-speed counting input ports (12KHZ). Output Point Y Components: Y0-Y17 are relay outputs, all using imported relays. Relay Contacts: AC not greater than 5A 250V; DC not greater than 30V 5A. Analog Input: 6 channels of analog input, 12-bit accuracy. AD0-AD2 are voltage inputs (0-10V), AD3-AD5 are 0-20MA current inputs. Use the RD3A command to read analog quantities. Analog Output: 2 analog outputs, 12-bit accuracy, output voltage: 0-10V. Use the WR3A command to output analog voltage. Intermediate Relay M: M0-M3071, save area can be set from M0-M1023. Step Point S: S0-1023, save area can be set from S0-1023. 100ms Timer: T0-T199, accumulated power-off save T184-T199. 10ms Timer: T200-T249, accumulated power-off save T246-T249. 1ms Timer: T250-T383, where T250-255 are cumulative. 16-bit Counter: C0-C199, C100-199. 32-bit Counter: C200-C219, save C220-C234 when power is off. 32-bit High-Speed Counter: C235-255; C235-240 are single-phase counters without frequency multiplication; C241-240 are single-phase counters with 2x frequency; C247-249 are two-phase counters without frequency multiplication; C250-252 are two-phase counters with 2x frequency; C253- are two-phase counters with 4x frequency. Register D: D0-D7999, save interval can be set from D0-7999. Indirect Addressing Pointers V, Z: V0-7, Z0-7. P Subroutine Jump Number: P0-63. Interrupts: X0-5 external interrupts. Timer interrupts (1MS as a unit). Counter interrupts. Special M Section: M8000 is normally closed when running, M8002 is the start pulse, M8011 is the 10ms pulse, M8012 is the 100ms pulse. 1 x Industrial Control Board Your 100% satisfaction is our top priority.
