The AcroPack is 19.05mm longer than the full length mini PCIe card at
50.95mm. It has the same mPCIe board width of 30mm and uses the same
mPCIe standard board hold down standoff and screw keep out areas.
The AP445 module is a bus isolated 32-channel output module. It provides
control for 32 solid state relays which are bipolar (may be used to switch
positive or negative voltages). The AP445 utilizes state of the art Surface-
Mounted Technology (SMT) to achieve its wide functionality and is an ideal
choice for a wide range of industrial I/O applications that require a high-
density, highly reliable, high-performance interface at a low cost.

1.3.2 Key Features
High Channel Count – Individual control of up to 32 (SPST-NO)
bipolar Solid State Relays (SSR’s) is provided.
Isolated Field I/O – Individual bipolar SSR’s provide isolation. There
are four groups (ports) of 8 channels, each which include separate
port commons to ensure port-to-port isolation. Individual ports are
isolated from each other and from the control logic.
Low-Side or High-Side Switch Configuration – Each group of eight
channels can be connected directly to positive or negative supplies
for high (hot) side switching. Alternatively, each group of eight
channels can be connected to common for low side switching
applications.
TTL Compatible – When configured as a low side switch will sink
32mA at 0.2 volts. Sourcing can be controlled by on-board surface
mount or external pull-up resistors. On-board surface mount
resistors are depopulated by default. Please contact factory for a
custom configuration.
Power Up & System Reset Fail-Safe – For safety, the outputs are
turned OFF upon power-up and a system reset. Thus, the SSR’s will
