surges with transient suppression. Data-logger-to-AM16/32B cabling requires a minimum of six
and as many as nine individually insulated wires with shields.

Power

:
Unregulated 9.6 to 16 VDC
Current drain
Quiescent:
< 210 µA
Active:
6 mA typical in 2x32 mode
11 mA typical in 4x16 mode
Reset (RES)
1
:
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 channel advance;
AM16/32B is also reset).
Clock (CLK)
1
:
On the transition from <1.5 V to >3.3 V, a channel 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.
