Power Consumption

Power Consumption

The power consumption and heat dissipation is dependent of number of slots
equipped in the rack and can be approximated as follows:
Analog Inputs - Protection & CM

16 to 64 analog differential inputs

Half of the total number of analog differential inputs (which can be 8 to 32 analog
inputs) supports RTD (Pt100, 3-wire) temperature sensors
 Temperature input sensor Pt100 (100 Ω at 0 °C, 0.00385 Ω/ °C)

Individual 24 V (23.5-28 V) power supply, maximum 30 mA per channel

Selectable standard accelerometer power supply (constant current 8 mA)

Input range: ±23 V

Impedance: >100 kΩ
Digital Inputs - Protection & CM

8 to 32 digital opto-isolated inputs

Half of the total number of digital opto-isolated inputs (which can be 4 to 16 digital
opto-isolated inputs) supports Eddy current probes

Individual 24 V (23.5-28 V) power supply, maximum 30 mA per channel

Disarm functionality

Outputs - Protection


16 to 64 electrically isolated 4–20 mA outputs

Buffered analog channels on D-sub, maximum ±11 V, signal 1:2, cutoff frequency
(-3 dB) at 60 kHz

Buffered digital channels on D-sub, 5 V TTL signal

Two selectable buffered analog channels on front panel BNC, maximum ±11 V,
signal 1:2, cutoff frequency (-3 dB) at 60 kHz

One selectable buffered digital channel on front panel BNC, 5 V TTL signal

Power to the rack = number of slots used x 75 W (including sensor power etc.)
(max 300 W)
Heat dissipation from rack = number of slots used x 50 W (max 200 W)
 Usage of redundant power has no significant effect on the above
numbers.
