This is the second generation
S7-200PLC input simulator
This section for the CPU224 CPU224XP special, for product models are as follows:
The emulator is simple to use, directly connected to S7-200PLC Of the input port, you can simulate the digital signal input, easy for beginners to learn to use, but also to facilitate debugging some programmers I / O Procedures, saving wiring time, only need to give PLC Connected to a working power can be completely no extra wiring can be based on PLC Up led Lights, to debug some of the more complex digital logic program.For maintenance testing PLC Of the staff, is also a great convenience and shorten the investigation CPU I / O The time of failure.
The input emulator is also derived PLC Its own input DC24V Of the switching power supply, user-friendly in the case of reducing the wiring, you can supply the relevant products (such as touch screen, its own expansion module)
The input emulator is in PLC Self-power output DC24V Of the port in series with a specification 0805Resistance for0Of the chip resistor, the user can take their own electricity needs to replace the corresponding insurance patch, the external power short circuit can be more effective protection PLC Input side of the role of power
