10 VMM2404
Inputs
The VMM2404 has 3 main types of inputs, as follows:
 Programmable digital inputs (can be used as active high, active low, or power
control)
 Dedicated addressing inputs
 Programmable multi-purpose inputs (can be used as analog, digital, or
frequency)
Note: Do not connect inputs directly to unprotected inductive loads such as
solenoids or relay coils, because they can produce high voltage spikes that
may damage the VMM2404. If an inductive load must be connected to an
input, use a protective diode or transorb.
3.1. Programmable Multi-Purpose Inputs
The VMM2404 has programmable multi-purpose inputs that can be configured
either as analog, digital, or frequency (ADF) through software, as follows:
 INPUT1_ADF through INPUT15_ADF
3.1.1. Multi-Purpose Used as Programmable Digital Input
Digital inputs are typically used for electrical signals that are either on or off.
The following multi-purpose inputs can be used as digital inputs:
 INPUT1_ADF to INPUT15_ADF
Note: There are 15 other digital inputs in addition to these inputs (refer to
Digital Inputs on page 21 for more details).
