*1 The range guaranteed as a system (excluding items specially noted for the units and cassettes). *2 The temperature below the unit centre (30 mm) inside a control panel. *3 These specifications correspond to situations in which the unit is mounted on a DIN rail and in which the unit is mounted on the panel directly. *4 Conforms to JIS B 3502 and IEC61131-2. Number of scans: 10 times (100 minutes) in each of the X, Y, and Z directions *5 You can also configure the settings so that automatic reset is not used. *6 Only open collectors are supported. Line drivers are not supported. *7 You can set the target device by clicking "CPU system setting" and then "Power off holding" in KV STUDIO. *8 Reference value of input current. *9 The input response time corresponding to the input time constant can be calculated as shown below. (Response time) = (Circuit delay of the input circuit) + (Delay by the digital filter) 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 |
