*1.An external fuse must be connected to the safety relay output. The safety category depends on the fuse rating:
1)Safety Category 4 (EN954-1)
A fuse rated at 3.15 A max. must be connected externally to protect the safety relay output from contact welding. The current that can be applied to the relay contacts is limited by the fuse rating to 3.15 A max. (resistive load).
2) Safety Category 3 (EN954-1) or lower
A fuse rated at 5 A max. must be connected externally to protect the safety relay output from contact welding. The current that can be applied to the relay contacts is limited by the fuse rating to 5 A max. (resistive load). For details, refer to section 10.4.3.4 of prEN50156-1.
*2.This rating is for Modules with built-in relays. The durability conditions are an ambient temperature of 15 to 35℃ and an ambient humidity of 25% to 75%.
*3.This value is a reference value. The Modules are not designed to be used below this value. If a large load is applied even once, switching may not be possible for microloads.
Rated Current
The rated current depends on the type and number of Modules used, as shown below.
| Module type | Rated current |
| Main Module (E, N) | 150 mA |
| Input Module (L1, L2, B1, D1) | 150 mA |
| Relay Output Module (R, R1, R2) | 100 mA |
Example:
F3SX-N-L2L2R: 150 (N Module) + 150 (L2 Module) + 150 (L2 Module) + 100 (R Module) = 550 mA
Response Time
Non-delay (Instant Breaking) Models
| Model (N Modules) | Relay outputs | Auxiliary output (AS1) | ||
| ON → OFF | OFF → ON | ON → OFF | OFF → ON | |
| F3SX-NR(-S) | 35 ms | 135 ms | 25 ms | 105 ms |
| F3SX-N-[]R(-S) | 35 ms | 135 ms | 25 ms | 105 ms |
| F3SX-N-[][]R(-S) | 40 ms | 156 ms | 30 ms | 126 ms |
| F3SX-N-[][][]R(-S) | 45 ms | 177 ms | 35 ms | 147 ms |
ON-delay/OFF-delay Time Setting Models
| Model (N Modules) | Relay outputs | Auxiliary output (AS1) | ||
| ON → OFF *2 | OFF → ON *1 | ON → OFF | OFF → ON | |
| F3SX-N-RR1 *1 F3SX-N-RR2 *2 | 35 ms | 135 ms | 25 ms | 105 ms |
| F3SX-N-[]RR1 *1 F3SX-N-[]RR2 *2 | 40 ms | 156 ms | 30 ms | 126 ms |
| F3SX-N-[][]RR1 *1 F3SX-N-[][]RR2 *2 | 45 ms | 177 ms | 35 ms | 147 ms |
Note: The actual ON-delay time (time from interlock reset until output occurs) and OFF-delay time (time from when input turns OFF until output turns OFF) is calculated by adding the applicable times shown in the above table to the user-set time.
Example: If the OFF-delay for an F3SX-N-RR2 is set to 0.5 s (500 ms), the actual OFF-delay is 500 + 35 = 535 ms.
*1.R1 Modules (terminals 23/24, 33/34) support an ON-delay time setting using the Function Setup Software for the F3SX (F3SX-CD100-E) The ON-delay time is factory-set to 0 s (non-delay (instant breaking)).
*2.R2 Modules (terminals 23/24, 33/34) support an OFF-delay time setting using the Function Setup Software for the F3SX (F3SX-CD100-E) The OFF-delay time is factory-set to 0 s (non-delay (instant breaking)).

ON-delay/OFF-delay Time Setting Models
| Model (E Modules) | Relay outputs | DC solid-state safety output, auxiliary output | ||
| ON → OFF *2 | OFF → ON *1 | ON → OFF | OFF → ON | |
| F3SX-ER1 *1 F3SX-ER2 *2 | 35 ms | 135 ms | 25 ms | 105 ms |

| F3SX-E-[][][]R1 *1 F3SX-E-[][][]R2 *2 | 45 ms | 177 ms | 35 ms | 147 ms |
Note: The actual ON-delay time (time from interlock reset until output occurs) and OFF-delay time (time from when input turns OFF until output turns OFF) is calculated by adding the applicable times shown in the above table to the user-set time.
Example: If the OFF-delay for an F3SX-E-D1D1D1R2 is set to 1 s (1,000 ms), the actual OFF-delay is 1,000 + 45 = 1,045 ms.
*1.R1 Modules (terminals 23/24, 33/34) support an ON-delay time setting using the Function Setup Software for the F3SX (F3SX-CD100-E) The ON-delay time is factory-set to 0 s (non-delay (instant breaking)).
*2.R2 Modules (terminals 23/24, 33/34) support an OFF-delay time setting using the Function Setup Software for the F3SX (F3SX-CD100-E). The OFF-delay time is factory-set to 0 s (non-delay (instant breaking)).
