1. Overview

Y113 is an RS485 seven-segment LED display module designed for industrial field applications. One product family covers submodels with 1 to 6 digits, with overall dimensions varying by digit count. The module uses the Modbus RTU protocol. The host can refresh the display by writing registers, and parameters such as brightness, decimal point, flashing, slave address, and baud rate are configurable.

ItemDescription
Form factorPanel-mount seven-segment LED display with a rear 4-pin terminal for power and RS485
InterfaceRS485 (A/B) and DC power terminals
ProtocolModbus RTU slave, default address 1
Display content0 to 9, A to F, -, ., with decimal point and flashing support
Submodel options1 to 6 digits, with enclosure size varying by digit count

2. Ordering Information

2.1 Model Naming

Y113-N

  • N = 1 / 2 / 3 / 4 / 5 / 6, indicating the number of display digits.

2.2 Submodel List

SubmodelDisplay DigitsTypical Application
Y113-11 digitSingle-status indication, single-character workstation code
Y113-22 digitsShort code display, counter status
Y113-33 digitsSingle-point current, pressure, or temperature display
Y113-44 digitsIndustrial scales, equipment room parameter display
Y113-55 digitsHigh-resolution process value display
Y113-66 digitsProduction line or energy data with a wider numeric range

2.3 Packing List

  • Seven-segment display module x1
  • 4-pin terminal block, pre-soldered
  • Quick start card with factory default parameters

3. Key Features

  1. One platform, multiple digit options: A single Y113 product family covers 1-digit to 6-digit display requirements.
  2. Direct Modbus display update: Refresh the display through register writes using 0x06 or 0x10.
  3. Non-volatile parameter storage: Address, baud rate, brightness, and power-on mode are retained after power loss.
  4. Easy commissioning: Supports all-segments-on, all-segments-off, single-digit writes, batch writes, and flashing control.
  5. Industrial communications: RS485 differential signaling with a default data rate of 9600 bps and support for higher baud rates.

5. Interface and Indicators

TerminalDescription
V+DC 9 to 24 V positive
V-DC negative, common ground with RS485 GND
ARS485 A (+) differential line
BRS485 B (-) differential line

Indicators

  • RUN: Steady on after power-up and flashes rapidly during parameter writes.
  • COMM: Flashes during communication and turns off after about 5 seconds without data.

6. Installation and Wiring

  1. Select the correct panel cutout for the submodel digit count and secure the module in place.
  2. Wire the terminals in the V+ / V- / A / B order. Shielded twisted pair is recommended for RS485, with 120 ohm termination at both bus ends.
  3. Connect the power ground, RS485 GND, and host ground together to reduce common-mode interference.
  4. Use a unique slave address for each device on the same RS485 bus.
  5. During commissioning, use the all-segments-on or all-segments-off command first to verify the hardware link, then switch to the normal display mode.
