Channels

Relay

Overview

Relay channels can open or close a contact for a higher voltage circuit using a lower level control voltage. The Relay output channels work as a physical on/off switch, and are used to drive higher voltage devices with a lower controlling voltage.

You can configure the following Relay output channel options:

zYou can choose to manually activate/deactivate the Relay output.

zYou can choose to manually activate/deactivate the Relay output and then specify that the Relay output will either pulse (you get to specify the active and inactive pulse times) continuously or for a specified number of pulse counts.

zYou can choose to manually activate/deactivate the Relay output and then specify a delay before the output goes from inactive to active or active to inactive.

zYou can also specify a failsafe action that can either active or inactivate the Relay output when the failsafe timer is triggered (see Failsafe Timer Functionality on page 132 for more information).

In an industrial freezer warehouse, the IOLAN A4R2 is used to monitor humidity transducers, which are used to help prevent freezer burn. If the humidity reaches a certain percentage (monitored by an Analog channel) a syslog message is sent to the Monitoring Application, causing the Relay channel to activate an internal freezer dehumidifier. The Relay channel is deactivated when the Analog channel sends a clear syslog message to the Monitoring Application and the Relay channel is deactivated.

DS1, TS2 specifications

Perle Systems TS2 and DS1 are advanced serial-to-Ethernet devices designed to facilitate seamless integration of serial devices with modern IP networks. These devices serve as crucial tools for businesses looking to enhance their communication capabilities while leveraging existing infrastructure.

One of the standout features of the Perle TS2 and DS1 is their ability to support multiple serial protocols including RS232, RS422, and RS485. This versatile support allows businesses to connect various legacy devices to their networks, ensuring that critical equipment can still communicate effectively in an increasingly digital landscape.

The TS2 model is particularly noted for its dual serial ports, enabling simultaneous communication with multiple devices. This capability is invaluable for applications requiring real-time data transmission, such as remote monitoring and automated control systems. The DS1 model, on the other hand, is designed for single-port use, making it an ideal solution for smaller-scale operations or specific single-device connections.

Both the TS2 and DS1 incorporate advanced features such as configuration through a web interface, which simplifies setup and management. Users can easily access device settings and monitor performance metrics remotely, enhancing operational efficiency. These devices also support various network protocols such as TCP/IP, UDP, and ICMP, ensuring compatibility with a wide range of network architectures.

In terms of security, Perle Systems prioritize user data protection. The TS2 and DS1 offer features including SSL encryption and SSH protection, providing an added layer of security for sensitive information transmitted over the network. This is particularly important for industries where data integrity and security are paramount, such as healthcare and finance.

Additionally, the rugged design of both devices ensures reliable performance even in harsh environments. With extended temperature ratings and robust housing, the TS2 and DS1 can operate in diverse conditions without compromising functionality.

To summarize, the Perle Systems TS2 and DS1 provide a reliable and flexible solution for connecting legacy serial devices to modern networks. With their support for multiple serial protocols, web-based management, robust security features, and rugged design, these devices cater to a variety of industries looking to modernize their communication infrastructure while maintaining existing equipment. Whether for large-scale operations or smaller implementations, the TS2 and DS1 equip businesses with the tools needed for effective serial communication in an IP-driven world.
