Campbell Scientific AM416 Multiplexer - Manual (Page 8)

AM416 RELAY MULTIPLEXER
2
Wires from sensors and datalogger are
connected to the gray terminal strips. The set
of four terminals located near the strain-relief
flange are the connections for datalogger
control of the AM416 (Section 4.1). The
terminal strips that run the length of the AM416
are for measurement connections (Section 4.2). The sensor inputs are not spark gapped. All
terminals accept stripped and tinned lead wires
up to 1.5 mm in diameter. The datalogger is
connected to the AM416 through a minimum of
seven, but generally nine, individually insulated
lead wires.
