AM16/32B Specifications
Power
*
:
Unregulated 12 Vdc
Minimum
Operating Voltage:
from –55° to +40°C = 11.3 Vdc
from +40° to +85°C = 11.8 Vdc
(See FIGURE 3-1 for relay actuation times vs.
temperature and supply voltage.)
Current Drain
Quiescent:
<210 μA
Active:
6 mA typical in “2 x 32” mode
11 mA typical in “4 x 16” mode
Reset
*
:
A continuous signal between 3.3 Vdc and
8 Vdc holds the AM16/32B in an active state
(where a clock pulse can trigger a channel
advance).
A signal voltage <0.9 Vdc
deactivates the AM16/32B (clock pulse will
not trigger a scan advance; AM16/32B is also
reset).
Clock
*
:
On the transition from <1.5 V to >3.3 V, a scan
advance is actuated on the leading edge of the
clock signal; clock pulse should be a minimum
of 1 ms wide; maximum voltage is 8 Vdc.
Operational Temperature
Standard:
–25° to +50°C
Extended:
–55° to +85°C
Operational Humidity:
0 to 95%, non-condensing
