MOUNTING RACKS

Features

5 VDC output

Ideal for powering Optomux or mistic brain boards and I/O

Compatible with Raspberry Pi

Mounts directly on digital I/O rack

Brain mounts on top of the power supply

Operating temperature range: -25 to 65 °C

DESCRIPTION

The PBSA, PBSB, and PBSC 5 VDC power supplies are designed to work
with an Opto 22 digital I/O mounting rack connected to an Optomux®
E1 or B1 brain board, or a mistic™ B100 brain board. Each power
supply is sized to provide power for the brain board and logic power
for 16 digital I/O modules.

The PBSC can also be used with a Pamux® B5 brain board and is sized
to provide power for the brain, 16 modules, and a Term1 Pamux bus
terminator.

The brain board mounts directly on top of the power supply and the
power supply mounts directly to the mounting rack. Two screws on
the power supply make the electrical connection to threaded
contacts on the mounting rack.

PBSA power supply

Compatible with Raspberry Pi

The PSBC can also be used with a Raspberry Pi® and Opto 22’s Digital
I/O Carrier Board for Raspberry Pi (part number OPTO-P1-40P) to
monitor and control industrial devices.

To ensure sufficient, consistent, and reliable power to the Pi and I/O
modules, we recommend that you attach the power supply to the
mounting rack (and not directly to the Pi).

NOTE: If your Pi uses USB-powered peripherals like hard drives or WiFi

, the PBSC may not provide sufficient current. We recommend

dongles
instead a 5 V power supply rated 2.5 A to 5 A; for example,
Opto 22’s SNAP-PS5.

For the complete list of supported mounting racks, brain boards, and
carrier boards, see “Specifications” on page 2.

SPECIFICATIONS

To bench test the power supply or check the voltage, connect the
appropriate rack and brain board to the power supply.

Because the power supply requires a load to regulate the voltage, no-load
readings will not be accurate.
