● Auxiliary speed change relay 1A 110/125 volts ● The manufacturer has stopped production ● Relay module components 1. General auxiliary relay FX series PLC general auxiliary relay has no power failure protection function. In FX series PLC, except input relay and output relay component numbers are octal, other programming components are decimal. Blackout protection diagram Blackout protection diagram If the power supply is interrupted suddenly while the PLC is running, the output relay and the general auxiliary relay will all be turned OFF. If the power supply is switched ON again, it will remain OFF except for those turned on by an external input signal. 2. Battery backup/latch auxiliary relay Some control systems require the memory of the instantaneous state of the power supply interruption, and reproduce its state after re-energized, battery backup/latch auxiliary relay can be used in such situations. Use lithium batteries to hold the contents of image registers in RAM or save them in EEPROM during power outages. They simply remain off instantaneous for the first scan cycle after the PLC is powered back on The state of In order to take advantage of their power off memory function, a circuit with memory function can be used. Let X0 and X1 in Figure 3-7 be the start button and the stop button respectively. M500 controls the external motor through Y0. If M500 is in the state of 1 when the power is interrupted, M500 will remain in the state after re-energization due to the memory of the circuit, so that Y0 remains ON and the motor starts running again. 3. Special auxiliary relay Special auxiliary relays total 256 points, they are used to represent some state of PLC, provide clock pulse and mark (such as carry, borrow mark), set the operation mode of PLC, or used for step control, forbid interrupt, set the counter is counting or counting. Special auxiliary relays fall into two categories: (1) contact utilization type By the PLC system program to drive the contact to use the type of special auxiliary relay coil, in the user program directly use its contacts, but they can not appear in the coil, the following are several examples: Waveform diagram Waveform diagram M8000(Operation monitoring) : When the PLC executes the user program, M8000 is ON; When the execution is stopped, M8000 is OFF M8002(initial pulse) : M8002 is ON only during one scanning cycle when the M8000 changes from OFF to ON. The normally open contact of M8002 can be used to keep the power off Element initialization resets or initializes them. M8011 ~ M8014 are 10ms, 100ms, 1s and 1min clock pulses respectively. M8005(lithium battery voltage drop) : When the battery voltage drops to the specified value, it becomes ON. Its contacts can be used to drive the output relay and external indicator to remind the staff to replace the lithium battery.
