RS-485 network termination module, 1 module MAX-LT-04

RS-485 Termination Module – Key to Reliable Communication

The MAX-LT-04 termination module is a compact device designed to improve the quality and stability of data transmission in RS-485 networks. Its main task is to terminate the signal line, polarize and amplify the signal, which translates to eliminating errors and ensuring reliable communication. This is an ideal solution for both installers of automation systems and end-users who value stable device operation.

Application and functionality

The MAX-LT-04 module finds application in control systems, industrial automation and anywhere where RS-485 communication is used. Terminating the signal line with this module prevents wave reflections that can interfere with data transmission. Polarization is particularly important in networks where some devices do not have a GND reference point. Signal amplification allows increasing the network range and improving communication quality over longer cable lengths.

Construction features and mounting

The MAX-LT-04 module is characterized by compact dimensions – it occupies only one module (18 mm wide), which facilitates its mounting on a standard 35 mm rail. Screw terminals with a capacity of 2.5 mm² ensure safe and reliable wire connections. The module housing provides an IP20 degree of protection, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The circuit current is 10 mA at a supply voltage of 15÷30V DC. The tightening torque of the terminals is 0.4 Nm. The operating temperature of the module is in the range of -25°C to +50°C, which allows its use in various environmental conditions.
