6.4 Triac (SSR) Output [FX2N-16EYS]
6.4.1 Specifications
6.4.2 Handling of triac output
1. Output terminals
On the triac output type units/blocks, one common terminal is
used for 8 points.
Therefore, the common terminal blocks can drive loads of
different circuit voltage systems (for example, 100V AC and
200V AC).
2. Circuit insulation
The PLC internal circuit and the output element (triac) are insulated with a photo-thyristor.
The common terminal blocks are separate from one another.
3. Display of operation
When the photo-thyristor is driven, the LED is lit, and the output triac is turned on.
4. Response time
The time from when the photo-thyristor is driven or shut down until the output triac is turned on and until it is
turned off is 1ms or less and 10ms or less, respectively.
