MOXA SPL-24 Series PoE Splitter

MOXA-SPL-24-Series-PoE-Splitter

Overview

The SPL-24 plays the role of PD, and splits the data signal and power signal that are transmitted from the PSE. The SPL-24 plays a dual role of providing power to industrial devices, and enabling Ethernet connections.
The SPL-24 have a wide operating temperature range of -40 to 75°C, and are designed to withstand a high degree of vibration and shock. The rugged hardware design makes the SPL-24 perfect for ensuring that your Ethernet equipment can operate in critical industrial environments, such as in hazardous locations, and complies with FCC and CE standards.

NOTE Throughout this Hardware Installation Guide, we use EDS as an abbreviation for Moxa EtherDevice Switch, and we use SPL as an abbreviation for Moxa PoE Splitter:  SPL = Moxa PoE Splitter

Wiring Requirements

WARNING
Do not disconnect modules or wires unless the power supply has been switched off or the area is known to be non-hazardous. The devices may only be connected to the supply voltage shown on the type plate. The devices are designed for operation with a Safety Extra-Low Voltage. Thus, they may only be connected to the supply voltage connections and to the signal contact with the Safety Extra-Low Voltages (SELV) in compliance with IEC 60950-1/EN 60950-1.

WARNING
The power for this product is intended to be supplied by a Listed Power Unit, with output marked LPS, and rated to deliver 48 VDC at a maximum of 300 mA.

WARNING
This unit is a built-in type. When the unit is installed in another piece of equipment, the equipment enclosing the unit must comply with fire enclosure regulation IEC 60950-1/EN60950-1 (or similar regulation).

WARNING

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your Moxa EtherDevice Switch. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

You should also pay attention to the following items:

  • Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
    NOTE: Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.

  • You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

  • Keep the input wiring and the output wiring separated.

  • It is strongly advised that you label the wiring to all devices in the system when necessary.

Mounting Dimensions

DIN-Rail Mounting for SPL-24
The plastic DIN-Rail attachment plate should already be fixed to the back panel of SPL-24 when you take it out of the box. If you need to reattach the DIN-Rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the figures below.

STEP 1: Insert the top of the DIN-Rail into the slot.
STEP 2: The DIN-Rail attachment unit will snap into place as shown below.

To remove the SPL-24 from the DIN-Rail, insert a flat-blade screw driver horizontally into the DIN-Rail kit under the SPL-24, and then pull it upwards and release SPL-24 towards you away from the
DIN-Rail.

Grounding the SPL-24

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the right most contact of the 3-contact terminal block to the grounding surface prior to connecting devices.

ATTENTION: This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.

Wiring the SPL-24’s Power Outputs

The two left-most contacts of the 3-contact terminal block connector on the SPL-24’s top panel are used for 24 VDC output. Top and front views of one of the terminal block connectors are shown here.

  • STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals.
  • STEP 2: To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connector.
  • STEP 3: Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on SPL-24’s top panel.
