APPENDIX B. DIFFERENCES BETWEEN THE AM416 AND THE AM32
The AM416 differs from Campbell Scientific's
AM32 multiplexer in the following ways:
1. The AM416 switches sixteen sets of four
lines at a time (4 x 16). The AM32 switches
thirty-two sets of two lines at a time (2 x 32).
2. The AM416 is packaged in an aluminum
case that should decrease temperature
gradients across the multiplexer terminal
strips.
3. The AM416 is smaller.
4. The AM416 contains terminals and circuitry
for sensor shield wires. This circuitry allows
sensor shield wires to be routed through the
multiplexer and grounded at the datalogger.
5. The packaging of the AM416 allows for
strain relief of lead wires on the
multiplexer's case.
6. The AM416 contains diodes between
shields and power ground for transient
protection.
