IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures in
designing any type of control or monitoring system. This is
especially important where economic property loss or human life is
involved. It is important that the user employ satisfactory overall
system design. It is agreed between the Buyer and Acromag, that
this is the Buyer's responsibility.
1.0 GENERAL INFORMATION
The PCI Mezzanine Card (PMC) Series PMC408 is a 32-
channel combination digital input/output board. This model supports
both 0 to 60V DC inputs, and 60VDC low-side switch outputs, in any
combination up to 32 channels. As a combination input/output
module, input channels on this model can be used for “loopback”
monitoring of the output channel states. Up to 8 input channels can
be programmed to generate Change-Of-State (COS), Low, or High
level transition interrupts. The PMC408 utilizes state of the art
Surface-Mounted Technology (SMT) to achieve its high channel
density and is an ideal choice for a wide range of industrial control
and monitor applications that require high-density, high-reliability,
and high-performance at a low cost.
The PMC408 module is available in standard and extended
temperature ranges as follows;

KEY PMC408 FEATURES
•
High Channel Count
- Interfaces with up to 32 input/output
points. Input and output channels may be intermixed in any
combination. The input circuitry of a single channel can also
be used to monitor the output state of the same channel to
efficiently implement “loopback” output control.
•
TTL-Compatible Input Threshold
- Input threshold is at TTL
levels and includes hysteresis.
•
Input Hysteresis
- Buffered inputs include hysteresis for
increased noise immunity.
•
Programmable Change-of-State/Level Interrupts -
Interrupts are software programmable for any bit Change-Of-
State or level on up to 8 channels.
•
Loopback Output Control & Fault Diagnostics
- Input and
output circuitry is connected in tandem to each I/O channel,
making it directly compatible for “loopback monitoring” of the
output channel states. This feature can also be used to
