Scanner Card HO112
Speci�cations

Channels: 8 (4-wire) Switching: bistable, �oating relais Thermal voltage: typ. 500 nV, max. 1μV*) Max. voltage between 2 contacts: 125 Vpk Max. measuring voltage: 125 Vpk - also V/Ω-input Volt-Hertz-Product: � 1 x 106 V · Hz Max. switching current: Max.contact resistance: Life time: Insulating resistance: Capacity: Switching delay: Measurement delay: 1 Aeff approx. 1 Ω (each wire) 2 x 108 switches (0.1 A; 10 V ) 3 GΩ **) >100 pF, between contacts 20 ms between 50 ms and 300 ms
DC

*) max. 1μV after a warm-up of 1.5 h **) at rel. humidity < 60 %

Miscellaneous: With built-in Scanner Card HO112 voltage measurements are only possible up to 100 V. That means that the 600 V range of the voltage measurement functions is automatically inactive. Pin 1 is the ground connection. Channel BP is used to supply the other channels with current, e.g. for suppling sensors, LEDs etc.
