Why Choose the LS Electric GSL-DT4C1 Rnet Smart I/O Module?

The GSL-DT4C1 is a robust Rnet Smart I/O module featuring 16 opto-isolated digital inputs and 16 PNP transistor outputs. Operating on 20.4–28.8 V DC, it integrates seamlessly into LS Electric’s Rnet (Rapid Network) architectures, offloading I/O channels from central PLCs and simplifying wiring in distributed control systems.

Key Features of the GSL-DT4C1 Module

  • Operating Voltage: 20.4–28.8 V DC
  • Digital Inputs: 16 opto-isolated channels, 19–28 V DC sink type
  • Transistor Outputs: 16 PNP outputs, 0.1 A per channel
  • Rnet Interface: 1 Mbps deterministic communication
  • Form Factor: 176.6 × 50 × 39 mm; DIN-rail mountable
  • Diagnostics: LEDs for power, network, and individual I/O status
  • Certifications: CE compliant
  • Temperature Range: 0 °C to +50 °C operating

Frequently Asked Questions About the GSL-DT4C1

How to Install the LS Electric GSL-DT4C1 Module

Snap the GSL-DT4C1 onto a 35 mm DIN rail. Connect 20.4–28.8 V DC to the power terminals. Wire field devices to the input and output screw terminals. Plug the Rnet cable into the network port, set the station address via DIP switches, and power on. Confirm operation by checking the diagnostic LEDs.

LS Electric GSL-DT4C1 – Rnet Smart I/O with 16 DI & 16 PNP DO

The GSL-DT4C1 delivers compact, decentralized control by providing 32 discrete I/O points directly on the Rnet network. Its opto-isolated inputs and PNP outputs ensure signal integrity and minimize interference. The integrated Rnet adapter enables fast, reliable scanning by your PLC or Rnet master, reducing latency and simplifying system layout.

Built for harsh industrial settings, the module’s rugged enclosure and wide temperature range maintain performance under vibration, temperature extremes, and electrical noise.

Frequently Asked Questions

The inputs support standard 19–28 V DC sink-type sensors, including proximity and limit switches.

No. Power down the network segment before insertion or removal to avoid data corruption.

Up to 64 Rnet stations per network segment, subject to PLC master capacity.

Outputs default to off on Rnet fault; inputs hold last state. Configure safe state in PLC logic.

Use the PLC’s Rnet configuration software or the IMO firmware tool via Rnet to upload new firmware.


For reliable distributed I/O in Rnet systems, choose the LS Electric GSL-DT4C1 to streamline wiring and maintain high performance across your automation network.
