Table 7 – Parallel Input connections.
Two forms of input signal can be applied to the Parallel Inputs connector:
Voltage Inputs, and Contact Closures. When a specific input on the V16+ is
configured for Voltage Inputs, power for the connection is provided by an
external source (in-rack power supply etc.), but when the input is configured as
a Contact Closure, power is taken internally from the V16+.
