TTL inputs & outputs
Both the TTL inputs and outputs are default = high (3.3 Volt). The TTL in-
puts are level triggered: the contacts require a minimum TTL-low pulse du-
ration of 100 ms. If multiple activations are required the next pulse should
be given after 100 ms TTL high. When the input is kept low, only one acti-
vation will occur.
Relays
The ROXY Exceed has 2 free programmable contact closure outputs:
•
Relay1: pin 1 normally closed, pin 2 normally open, pin 3 common.
•
Relay2: pin 4 normally closed, pin 5 normally open, pin 6 common.
The maximum rating for these contact closure outputs are 24 VDC (switch-
ing voltage) and 0.25 A. The relays can be controlled in the Dialogue Elite
software and Clarity Chromatography software.
AUX
The ROXY Exceed has 4 free programmable TTL outputs AUX1
– AUX4
(pin 7
– 10). These contacts are default ‘high’ 3.3V (inactive), when active
the
status is ‘low’ 0V.
Overload
The overload output (pin 11) can be used to monitor if the cell current goes
out of range during a measurement. An
‘Out of range’ error appears when
the cell current I
cell
exceeds the limit of the current range at which the
measurement is performed. See figure on the next page.
