| Output modes | A, B, D, E, F, or Z | |
| Inputs | Input signals | For Counter: CP1, CP2, and reset For Timer: Start, gate, and reset |
| Input method | No-voltage input (contact short-circuit and open input) Short-circuit (ON) impedance: 1 kΩ max. (Approx. 2 mA runoff current at 0 Ω) Short-circuit (ON) residual voltage: 2 VDC max. Open (OFF) impedance: 100 kΩ min. Applied voltage: 30 VDC max. | |
| Start, reset, gate | Minimum input signal width: 1 or 20 ms (selectable) | |
| Power reset | Minimum power-opening time: 0.5 s | |
| Control output | SPDT contact output: 3 A at 250 VAC/30 VDC, resistive load (cosΦ = 1) | |
| Minimum applied load | 10 mA at 5 VDC (failure level: P, reference value) | |
| Reset system | External, manual, and power supply resets (for timer in A, B, D, E, or Z modes) | |
| Sensor waiting time | 260 ms max. (Inputs cannot be received during sensor wait time if control outputs are turned OFF.) | |
Note: The figures given for maximum counting speed are for incrementing or decrementing operation with a prescale value of ×1. If prescaling is used and 5 kHz is set, the maximum counting speed will be reduced to about half. The maximum counting speed will also be reduced to about half when the up/down mode is selected.
