Cautionary Notes The AM16/32B is not designed to multiplex power. Its intended function is to switch low level analog signals. Switched currents in excess of 30 mA will degrade the relay contacts involved, rendering that channel unsuitable for further low level analog measurement. Customers who need to switch power are directed to Campbell Scientific's SDM-CD16AC, A6REL-12, or A21REL-12 relays. Changing the setting of the mode switch from "4x16" to "2x32" connects COM ODD H to COM EVEN H and also COM ODD L to COM EVEN L. After wiring AM16/32B, exercise due care to avoid inadvertently putting excess voltage on a line or short circuiting a power supply which might damage connected devices such as datalogger, wiring panel, sensor, or multiplexer (not covered under warranty). v

Cautionary Notes
The AM16/32B is not designed to multiplex power.
Its intended function is to
switch low level analog signals.
Switched currents in excess of 30 mA will
degrade the relay contacts involved, rendering that channel unsuitable for
further low level analog measurement.
Customers who need to switch power
are directed to Campbell Scientific’s SDM-CD16AC, A6REL-12, or
A21REL-12 relays.
Changing the setting of the mode switch from “4x16” to “2x32” connects
COM ODD H to COM EVEN H and also COM ODD L to COM EVEN L.
After wiring AM16/32B, exercise due care to avoid inadvertently putting
excess voltage on a line or short circuiting a power supply which might
