Connections between CXDI-80C system and X-ray generator
Connection conditions
1. The X-ray exposure signal line (including the switching mechanisms) must be insulated,
and the total impedance must be less than 100 Ω . The device delay time must be 1ms or
less.
2. The maximum contact voltages of the X-ray exposure permission signal line must be AC
250V and DC 30V whereas the current must be 10mA to 2A.
Furthermore, only an insulated secondary power supply can be connected.
3. The protective ground of the X-ray generator must have the same potential as the system
itself. The device delay time must be 20ms or less.
