Electrical parameters:
Wetting voltage: 24V DC.
Local bus current: When rated at 12V DC, the typical value is 50mA, with a maximum of 75mA per card.
On site circuit power: per card 150mA@24V DC (+20%/-15%), 15mA per card at 120V AC.
Isolation characteristics:
Each channel is optically isolated from the system, and the factory test voltage is 1500V DC.
Each channel is optically isolated from the system at a detection level of 250V AC, with a detection level of>1.4mA when turned on and<0.56mA when turned off.
