*1 The guaranteed range as a system (excluding elements specifically indicated for the units and cassettes).

*2 The temperature below the center of the unit (30 mm (1.18")), inside a control panel.

*5 Automatic reset can also be configured to not be used.

*6 Only open collector drivers are supported. Line controllers are not compatible.

*7 The destination device can be configured by clicking “CPU system setting” and then “Power off holding” in KV STUDIO.

*8 Reference value of the input current.

Example: Maximum response time, when the input time constant is set to 500 µs

• OFF to ON: 30 µs (circuit delay) + 400 µs (digital filter) = 430 µs
• ON to OFF: 50 µs (circuit delay) + 400 µs (digital filter) = 450 µs
