Integrated HMI PLC All In One



  1. Customized HMI PLC all-in-one is the first choice for small and medium-sized automation, with multifunctional, stable performance, convenient maintenance, safe and reliable.
  2. Max support 6 analog inputs(7'')and 2 analog outputs, 12 bit precision. Analogs can be directly read by registers and for data output.
  3. Support multi-channel high-speed counting and high-speed pulse functions. High-speed counting conventional 6 single-phase 10KHz 
  4. The touch panel adopts 32bit CPU, which runs fast. The performance is equivalent to Tk series HMI.
  5. The HMI and PLC can be encrypted separately. PLC password with 12345678 can completely prohibit program reading, and cannot modify the clock data. (Note: PLC only supports 8-bit password encryption)
  6. Supports external interruption and watchdog function. 7 inch all-in-one machine can select 1 channel to load cell (accuracy is 24 bits) or a CAN communication port.
  7. Applies space 3.81mm pluggable terminal, which is convenient for wiring.
