*1 Power consumption of loads not included.
*2 The operating time is the time it takes for the safety contact to close after the safety inputs and feedback-reset input are turned ON. Not includes bounce time.
*3 This is in normal operation. When executing non-regular self-diagnosis for Safety output circuit, G9SE operating time become 500 ms max..
*4 The response time is the time it takes for the safety main contact to open after the safety input is turned OFF. Includes bouncetime.
*5 This is initial value using the voltage-drop method with 1A at 5VDC.
*6 Use for each contact output an 8A fuse that conforms to IEC 60127 as a short-circuit protection device. This fuse is not included with the G9SE.
*7 Condition: G9SE is mounted to mounting surface with screw and the screw mounting attachment. In the case of DIN rail mounting, mount DIN rail with G9SE to the place without big vibration. (Amplitude guideline: Less than 0.15 mm half amplitude (0.3 mm double amplitude))
