Thermo Scientific Orbitrap Fusion Series Getting Connected Guide 19
4 Start In Receives the start signal from the contact closure
connection of a connected external device.
To activate this signal, the external device must pull the
signal either low (below 0.75 Vdc) or high (above
2.4 Vdc), depending on the polarity, for at least
100 ms by using a relay, an open-collector driver, or a
similar device that connects between pins 4 and 1.
Note
In the Instrument Configuration window, set
the contact closure signal to “High-to-low edge” or
“Low-to-high edge,” whichever matches the setting
for the connected external device.
5 Ready Out Provides a relay-driven programmable output signal to
the connected external device. The relay opens when a
method starts and closes when the method finishes.
Output: Maximum 24 Vdc, 3 A
6 Injection Hold Provides a relay-driven programmable output signal to
the connected external device, such as a fraction
collector.
Output: Maximum 24 Vdc, 3 A
8 RO/IH Common (return) connection for the Ready Out and
Injection Hold pins.
Analog Input
The two analog channels connect to two separate 12-bit analog-to-digital converters (ADC)
for on-demand conversion of the input voltage. The conversion rate depends on the MS
rate.
1 Chassis Earth ground (for pins 3 and 4).
3, 4 2V Max:
+ (positive, pin 3) and
– (negative, pin 4) (Channel 2) Provides a connection for an external
device, such as an LC instrument.
Input: 0–2 Vdc (voltage clamps at 5 Vdc)
5 Chassis Earth ground (for pins 7 and 8).
7, 8 10V Max:
+ (positive, pin 7) and
– (negative, pin 8) (Channel 1) Provides a connection for an external
device, such as an LC instrument.
Input: 0–10 Vdc (voltage clamps at 15 Vdc)
