45C987 Technical Specifications

Manufacturer Reliance Electric
Series Shark XL
Part Number 45C987

Product Description

The 45C987 device is a Shark XL network module. Both the Shark XL series and the 45C987 network module were made by Reliance Electric. Most of the time, you can find the 45C987 network module inside of our stock here at AX Control even though the Shark XL series is not being produced by Reliance Electric any longer. Check on the availability of this device using our website.

The 45C987 network module was designed so that it could allow a maximum of eight Shark XL systems to communicate with one another. Because of this, the 45C987 network module is a required product if you are hoping to connect a Shark XL system to the network.

On the 45C987 network module’s faceplate, you will find a status LED, terminals for network communication wires, and two rotary switches. Whenever the LED, which is labeled as “RUN,” is illuminated, then you will know that the module is transmitting data onto the network. The two rotary switches are used to define the node number of the module and the total number of nodes that are present on the system.

For connection purposes, the network cables that are recommended are a 20 gauge shielded twisted pair cable or a Belden 9436 cable. The total network cable length is up to 1000 feet or 300 meters. Additionally, the network refresh rate is calculated by taking the number of nodes and multiplying it by 10 milliseconds. There are a total of eight nodes, with one being a master node and seven being the slave nodes.
