An output from this module can drive an Allen-Bradley Size 5 motor
starter, provided its supply voltage does not drop below 92V ac. The
maximum load current the module can deliver is 2A per channel, not to
exceed 8A total per module.

1771-ODD AB Input module Brand new
The 1771-ODD module is designed for a 10mA minimum current on each
output circuit. The total continuous current the module supports is 8A (2A
maximum per channel). If this rating is exceeded, the module overheats
and damage may occur.
Suppression
Surge suppression circuitry is provided for the output triacs in this module.
To suppress high-voltage transients from the ac line, a metal-oxide varistor
(MOV) is provided between each set of terminals on the module. In each
output circuit an RC network limits the magnitude of voltage transients
that may occur when a device is wired in parallel or series with hard
contacts.
Loads with inductive characteristics may require additional suppression
devices. The impedance characteristic of the load is the most important
factor in selecting a suppression device; thus no single suppression device
can be recommended for every possible load. See Table 1 for acceptable
suppression devices for typical loads.

The isolated output module is powered by the power supply connected to
the I/O chassis backplane. The module requires a maximum current of
420mA from the +5V dc output of this supply. Total the current
requirements of this module with the other modules in the I/O chassis to
avoid overloading the supply or the I/O chassis backplane.
