Technical Specifications
Power Supply & Display Performance
The 485-80020 uses a wide 11–30 V DC power input for flexible industrial integration. It draws less than 350 mA current under no-load conditions to keep power usage low. Equipped with an 8-digit 7-segment LED display, the unit features 10 mm digit height that ensures clear reading, even in typical industrial working environments where visibility might be challenging.
Communication Interface Features
The 485-80020 supports SSI, RS485 and RS422 interfaces, which broadens its system compatibility across various industrial setups. Its SSI interface operates at 100 kHz to 750 kHz and offers both Gray and Binary code options for versatile data transmission. To ensure stable signal delivery, you can set SSI data bits from 12 to 31 while keeping the mono time above 20 µs. Moreover, the device is compatible with TRWinProg, EprogW32, LTProg and LLB protocols, enabling smooth configuration and integration.
SSI Mode & Cascading Function
You can set the 485-80020 as SSI Master, Slave or Monitor, depending on your specific system requirements. One of its key features is the ability to cascade multiple slave displays, which allows you to extend monitoring capabilities across multiple pieces of equipment. This cascading function simplifies the process of building multi-station display systems, as it requires only simple wiring and straightforward setup.
Programming Configuration
Programming the 485-80020 is convenient: you can use a USB port with the Windows-compatible TRWinProg tool for direct configuration. Alternatively, you can utilize RS485 with a USB/RS485 adapter to follow the same programming procedure, offering flexibility based on your available equipment. With a maximum data capacity of 26 Bit, the display is well-suited for most industrial measurement and position monitoring applications.
Adjustable Display Parameters
The 485-80020 offers extensive adjustability for display parameters to match your needs. For instance, you can shift decimal points across 0 to 7 digits to align with your measurement format, and you have the option to show or hide leading zeros based on your preferences. Additionally, output modes include signed/unsigned decimal, HEX and binary, catering to different data types and display requirements. You can also set the refresh time from 50 ms to 2000 ms, allowing you to balance update speed and operational stability.
Advanced Custom Functions
Beyond basic display features, the 485-80020 includes advanced custom functions for enhanced usability. You can select measurement units between millimeters and inches to display values directly in your preferred format. Slave units can either follow master settings or use independent user-defined parameters, providing flexibility for multi-unit setups. Furthermore, you can set independent offsets and custom scaling to match actual process values, define counting direction to align with mechanical movement, and configure voltage warning levels to monitor power stability.
Mechanical & Environmental Data
Mechanical Structure
The 485-80020 features a rugged impact-resistant plastic housing, which ensures durability and long service life in harsh industrial environments. Measuring 96 mm × 24 mm × 120 mm without connectors, it is compact enough for easy installation in tight control cabinets. The front panel cutout requires dimensions of 92.5±0.5 mm × 21.5±0.5 mm with a maximum panel thickness of 4 mm. At only 0.2 kg, the unit is lightweight, making it easy to handle and install without additional tools or support.
Environmental Ratings
The 485-80020 operates reliably in a temperature range of 0 °C to +60 °C, which covers most standard industrial working conditions. It holds an IP43 protection class according to DIN EN 60529:1991 standards, meaning it can resist moderate dust and water splashes common in factory environments. This environmental resilience ensures consistent performance even in less-than-ideal working conditions.
Installation Guide
Mechanical Installation
First, prepare a front panel cutout that matches the specified mounting dimensions to ensure a proper fit. Ensure the panel thickness stays under 4 mm, as exceeding this limit may prevent the unit from locking securely. Once the cutout is ready, mount the unit firmly to avoid vibration-related movement during operation, which could affect display stability or wiring connections.
Electrical Wiring
After mechanical installation, connect the 11–30 V DC power supply while ensuring correct polarity—this step is critical to protect the device’s internal circuits from damage. Next, wire the SSI, RS485 or RS422 lines based on your control system layout, ensuring all connections are secure and properly insulated. Additionally, ground the device properly to reduce electrical interference, which is especially important in busy industrial environments with multiple electrical components.
System Setup
Once wiring is complete, set the device to SSI Master, Slave or Monitor mode based on your system architecture. If you need to monitor multiple positions, cascade several slave units under one master to extend display capabilities. Finally, connect a PC via USB or RS485, launch the TRWinProg software, and set the required parameters—such as display format, scaling, and refresh time—to match your application needs.
