Moxa INJ-24A 0 to 60 °C operating temperature content_copy

The INJ-24A from Moxa is a high-performance PoE+ injector with Gigabit support, specifically designed for use in demanding industrial environments. It provides power and data transmission over a single network cable to power-hungry end devices such as PTZ cameras, Wi-Fi 6 access points, or industrial IoT gateways. The maximum output power is 60 W per port, double that of conventional PoE+ injectors, enabling the supply of devices with high energy requirements. The integrated 24/48 VDC voltage booster circuit ensures redundancy, even at low input voltage, and increases operational reliability.

Applications

The INJ-24A is designed for industrial applications where high reliability, robust construction, and high performance are required. It is particularly suitable for environments with high mechanical or electrical stress, such as production halls, factories, logistics centers, or industrial surveillance technology. The operating temperature ranges from 0 to 60 °C (standard model) and from -40 to 75 °C for the -T variant, making it suitable for extremely cold or hot environments as well.

Functions and Features in Detail

The injector features two RJ45 connectors: one data port and one PoE port, both supporting 10/100/1000BaseT(X). The Auto MDI/MDI-X and Auto-Negotiation functions enable flexible and automatic adaptation to connected devices. A DIP switch allows selection between Mode A (pins 1,2,3,6) and Mode B (pins 4,5,7,8) to adjust the PoE pinout configuration to the requirements of the end device. The integrated voltage booster circuit ensures stable power supply even with fluctuating input voltage.

Technology Explained Simply

The INJ-24A operates according to the IEEE 802.3af/at standard, which defines PoE technology for power delivery over the network cable. The maximum power of 60 W per port is sufficient for power-intensive devices. Power supply is via 24/48 VDC, with an operating voltage range of 22 to 57 VDC. The current draw is 2.71 A at 24 VDC, and the maximum self-consumption is 5.29 W (without connected device). Integrated protection functions include reverse polarity and overcurrent protection, enhancing operational safety.

Compatibility and Accessories

The injector is compatible with devices supporting the IEEE 802.3af/at standard. The integrated 24/48 VDC voltage booster circuit enables use with various power supplies. PoE control via the DIP switch allows adaptation to different device requirements. Mounting is done on a DIN rail or optionally on the wall, enabling flexible installation in various environments.

Mounting and Installation

The INJ-24A is connected to the power supply via a 4-pole, detachable terminal block. Mounting is either on a DIN rail or optionally on the wall. The robust metal construction and IP30 protection rating ensure safe operation in industrial environments. Installation requires no special tools, as the connections are easily accessible.

Operational Advantages

The INJ-24A offers high reliability due to its robust construction, 3 kV surge protection, and high MTBF of 2,407,739 hours according to Telcordia SR332. The integrated voltage booster circuit and DIP switch for PoE mode selection increase flexibility. The 5-year manufacturer's warranty underscores the quality and longevity of the device. The operating temperature ranges and environmental tests according to IEC 60068-2-31, -2-27, -2-6 guarantee stable performance under various environmental conditions.

Scope of Delivery

The scope of delivery includes the INJ-24A PoE+ injector, a quick start guide, a product test certificate (in Chinese), a product notice (in Chinese), and a warranty card.
