Used as load power supply. Different types of equipment cpu 221 ~ 226 have two types of cpu, with a different supply voltage and control voltage. The local digital input/output cpu 221 with 6 inputs and 4 outputs, cpu 222 with eight inputs and six outputs, cpu 224 with 14 inputs and 10 outputs with 14 points cpu 224xp inputs and 10 output points, cpu 226 with 24 inputs and 16 outputs. Local analog input/output cpu 224xp with 2 input, 1 output. Interrupt input allows a very high speed of the process to respond to the rising edge of the signal. High-speed counter cpu 221/222 4 high-speed counter (30khz), programmable and has a reset input, two independent inputs which can be added, by count, phase two can be connected to 90& # 176; of a/b phase incremental encoder cpu 224/224xp/226 6 high-speed counters (30khz), with the cpu 221/222 the same function. cpu 222/224/224xp/226 can be easily used digital and analog expansion module expansion. Can use the emulator (optional) input signal on the machine simulation for debugging user programs. Analog potentiometer cpu 221/222 1 cpu 224/224xp/226 2 cpu 221/222/224/224xp/226 pulse output 2-way high-frequency pulse output (maximum 20khz), used to control stepper motors or servo motors to achieve positioning tasks. Real-time clock such as filling time stamp information, record running time machine or process time control. eeprom memory module (option) can modify and copy the program as a quick tool (without programmer), and supporting software for archiving. Data back-up battery module for a long time. User data (such as the flag state, the data blocks, timers, counters) can be stored inside the super-capacitor of about 5 days. Optional battery module can be extended to 200 days storage time (10 years of life). Battery modules are inserted in the memory module slot. .
