SNAP-PS5 power supply
The SNAP-PS24 and SNAP-PS24U power supplies are designed for either of two purposes:
To provide primary power for a SNAP PAC S-series controller To provide 24 volts of DC loop power for SNAP analog modules
mounted on a SNAP PAC rack
The SNAP-PS5, SNAP-PS5-24DC, and SNAP-PS5U power supplies are designed to provide 5 VDC power for a SNAP PAC rack with an I/O processor (SNAP PAC brain or R-series controller) and I/O modules mounted on the rack. The combination of a rack, processor, and modules is called an I/O unit.
Opto 22 recommends using one SNAP power supply for each I/O unit and for each controller. Choose the power supply based on the load required for the I/O unit. See the power requirements tables starting on page 12 for help in determining the power supplies you need. Additional information on using power supplies can be found in the Opto 22 technical note Using Power Supplies with Opto 22 Systems (form #1271, available on our website,
All SNAP power supplies except the SNAP-PS5-24DC require AC input power. The SNAP-PS5U and SNAP-PS24U accommodate a wide range of AC input voltages, from 100 to 250 VAC.
The SNAP-PS5-24DC DC-to-DC power supply requires a 24 VDC input and is ideal for systems using DC backup power.
Each SNAP power supply can be mounted in one of two ways: next to the controller or SNAP I/O unit it powers, using the standard panel-mounting base, or directly on a DIN rail using the optional 35mm DIN-rail adapter.
AC or DC input power connections, as required by the model, are made to a removable terminal strip on top of the power supply. DC output power is then ready to be hooked up to the controller or rack using the attached wiring harness.
SNAP power supplies work with Wired+Wireless™ PACs and I/O units as well as standard wired PACs and I/O.
Notes for legacy hardware: SNAP power supplies are also compatible with Ethernet-based SNAP Ultimate, SNAP Ethernet, and SNAP Simple I/O, and with serial-based SNAP I/O units such as those with a B3000, SNAP-HA, or SNAP-B3000-MODBUS brain.

I/O UNIT POWER REQUIREMENTS
The tables starting on page 12 will help you determine the power supply needs for your system. Copy the power requirements worksheet and complete one for each distributed I/O unit.
In addition, keep the following power recommendations in mind. For more help with power supplies, see Opto 22 form #1271, Using Power Supplies with Opto 22 Systems.
Use a single power supply per rack
In general, we recommend you use an independent, isolated, regulated power supply locally with each rack. Local isolated supplies offer these advantages:
Short supply conductors, which minimize losses Power redundancy, so the failure of a single supply causes only a
single rack failure, not a total system failure Fewer voltage drops and ground loops (Voltage drops and
subsequent ground loops may occur when power is distributed over a large system.)
DATA SHEET
Form 1120-200129
PAGE 3
Always use a separate field supply
Use a separate power supply for the field side of the I/O. Using the rack supply for field actuation and monitoring defeats the isolation the I/O module offers and therefore increases the chance of a ground loop within the control system. Additionally, a sudden change of current on the field side can cause undesirable voltage fluctuations that may interfere with the controller or I/O unit’s operation.
Power wiring guidelines
Use one power supply per I/O unit. Use one power supply per controller. Use 14 AWG wire. SNAP power supplies have short wires to minimize voltage drop.
Do not extend the length of the wires. If you power multiple I/O units or controllers from one power
supply, use a star wiring topology. Do not daisy-chain power wiring from one device to the next.

INSTALLATION
Panel Mounting (standard)
Mount the SNAP power supply in a location where the attached red and black power wires will reach the “+” and “-” power terminals on the SNAP mounting rack or controller. Do not extend the wires.
DIN-Rail Mounting (optional)
1. For 35mm DIN-rail mounting, remove the four screws that fasten the panel mounting base plate to the power supply. Keep screws in a safe place.
2. Remove panel mounting base plate.
3. In place of the panel mounting base plate, use the four screws removed in step 1 to
fasten the DIN-rail adapter (purchased separately) to the power supply.
4. Mount the SNAP power supply on the DIN rail (next to the power connector on the I/O unit).

Wiring to a Standalone Controller
1. For a controller, check the controller’s specifications in its data sheet or user’s guide to make sure you have the correct power supply for the controller’s requirements.
2. Follow directions in the controller’s user’s guide to wire the power supply to the controller. The power supply’s red (or white-and-red) wire is the positive wire; the black (or white-and-black) wire is the negative wire.
Wiring to a SNAP I/O Unit
1. Using the power terminals on the SNAP mounting rack, attach the red wire to the “+” terminal and the black wire to the “-” terminal.
2. For the SNAP-PS5 (not illustrated): Using the removable input power connector on top of the power supply, apply 120 volts AC power between the two terminals marked “AC.” The ground terminal should be connected to ground.
3. For the SNAP-PS5-24DC (not illustrated): Using the removable input power connector on top of the power supply, apply 24 volts DC power between the two terminals marked “±DC.” The ground terminal should be connected to ground.
4. For the SNAP-PS5U (illustrated below): Using the removable input power connector on top of the power supply, apply 100– 250 volts AC power between the two terminals marked “AC.” The ground terminal should be connected to ground.

Opto 22’s groov Edge Programmable
Industrial Controller (EPIC) system gives
you an industrially hardened system with guaranteed-for-life I/O, a flexible Linux®­based processor with gateway functions, and software for your automation and IIoT applications.
groov EPIC I/O
groov I/O connects locally to sensors and equipment with up to 24 channels on each I/O module. Modules have a spring-clamp terminal strip, integrated wireway, swing-away cover, and LEDs indicating module health and discrete channel status.
groov I/O is hot swappable, UL Hazardous Locations approved, and ATEX compliant.
groov EPIC Processor
The heart of the system is the groov EPIC processor. It handles a wide range of digital, analog, and serial functions for data collection, remote monitoring, process control, and discrete and hybrid manufacturing.
In addition, the EPIC provides secure data communications among physical assets, control systems, software applications, and online services, both on premises and in the cloud.
Configuring and troubleshooting I/O and networking is easier with the EPIC’s integrated high-resolution color touchscreen. Authorized users can manage the system locally on the touchscreen or on a monitor connected via the HDMI or USB ports.
