CONNECTING RELAY DEVICES

The NET5308T-EXP supports up to four relay devices. Use them to trigger external devices. The unit supports both momentary and continuous relay operation, either normally open or normally closed.

You can operate the relay interactively, during an active connection, or automatically to coincide with certain events. Typical applications include activating a door, gate, or lock, or switching on lights or other electrical devices.

WARNING: Do not exceed the maximum ratings: 30 VDC, 2 A; 125 VAC, 0.5 A.

When wiring the connector:

•Use 16 to 26 AWG (0.14 to 1.5 mm2) wire that is rated for 250 V or higher. The insulation must be thick enough to protect against electrostatic discharge (ESD).

•Strip the relay control wire to 0.3 inches (7.6 mm).

•Insert the wire far enough into the connector so that the metal is not exposed.

•When using a relay with a higher load, install an external, more powerful relay.

The unit includes two 6-pin relay control terminal blocks. These blocks have tension clamps. Use a small screwdriver to open the clamp for a particular lead. Figure 16 shows how to wire the relay control terminal block and connect it to the NET5308T-EXP.

NOTE: The terminal block is keyed. It attaches only one way to the NET5308T-EXP.

NET5308T-EXP specifications

The Pelco NET5308T-EXP is an advanced network video encoder designed for high-performance video surveillance applications. This versatile device is notable for its ability to transform analog video feeds into digital signals, allowing for seamless integration with modern IP-based systems. This makes it an essential component for facilities looking to upgrade their security setups while retaining existing cameras.

One of the key features of the NET5308T-EXP is its capacity to handle up to eight analog video channels. This multi-channel capability allows users to manage multiple cameras through a single device, simplifying the installation and reducing the overall cost of upgrading surveillance systems. Each channel can process video in high-definition, ensuring that captured footage maintains clarity and detail, which is crucial for effective monitoring and incident investigation.

The NET5308T-EXP employs advanced H.264 video compression technology, which optimizes bandwidth usage without compromising video quality. This codec allows for the transmission of high-resolution video streams while minimizing data storage requirements. With the growing need for efficient data management in surveillance systems, this feature becomes invaluable, particularly in environments where bandwidth is limited.

Another significant aspect of the NET5308T-EXP is its support for Power over Ethernet (PoE). This technological integration enables the device to receive power and transmit data over a single Ethernet cable, greatly simplifying installation. It eliminates the need for multiple power sources and power adapters, allowing for cleaner setups and reducing cable clutter.

Moreover, the encoder includes advanced motion detection capabilities, which can trigger alerts based on movement within the camera’s field of view. These features can be essential for ensuring that security personnel are notified of potential security breaches in real time. Additionally, the device supports various networking protocols, enhancing its compatibility with a wide range of video management systems.

The NET5308T-EXP is designed for reliability and durability in various operating conditions. Its robust construction allows it to function in a range of environments, making it suitable for indoor and outdoor applications alike. With features such as video loss detection and alarm inputs, the device further assures its status as a top-tier solution for comprehensive security needs.

Overall, the Pelco NET5308T-EXP is an exceptional choice for organizations looking to modernize their surveillance technology without the need to overhaul existing infrastructure. With its multi-channel support, advanced compression technology, PoE capabilities, and intelligent alert systems, it represents a significant advancement in video surveillance technology, providing users with high-quality performance and flexibility.
