Why Choose the LS Electric GSL-RY2A Rnet Relay Output Module?
The GSL-RY2A Smart I/O module delivers two SPDT relay outputs on LS Electric’s Rnet (Rapid Network) platform. Operating at 20.4–28.8 V DC input, it provides flexible switching for higher-current loads, enabling decentralized control of solenoids, lamps, and contactors directly on the network—minimizing central PLC I/O usage and simplifying wiring.
Key Features of the GSL-RY2A Relay Output Module
- 2 Relay Outputs: SPDT form C contacts rated 5 A at 250 VAC / 30 V DC.
- Optical Isolation: Individual channel isolation for noise immunity.
- Rnet Interface: 1 Mbps deterministic network communication.
- Wide Voltage Range: 20.4–28.8 V DC operating voltage.
- Compact Size: 176.6 × 50 × 39 mm; DIN-rail mountable.
- Diagnostics: LEDs for power, network, and output status.
How to Install the LS Electric GSL-RY2A Module
Snap the GSL-RY2A onto a 35 mm DIN rail. Connect 24 V DC to the power terminals. Wire loads to the relay output terminals as NO/NC contacts. Plug the Rnet cable into the network port, set the station address via DIP switches, and power up. Confirm correct operation by toggling outputs and observing status LEDs.
LS Electric GSL-RY2A – 2 SPDT Relay Outputs on Rnet Smart I/O
The GSL-RY2A expands your Rnet network with two versatile relay outputs capable of switching AC or DC loads up to 5 A. Ideal for driving high-current devices such as solenoids, indicator lamps, and small motors, it offloads relay control from PLC cards and streamlines panel layouts.
With individual channel isolation and LED indicators, the module ensures reliable switching and rapid troubleshooting, even in electrically harsh environments.

Frequently Asked Questions
The SPDT contacts can switch up to 5 A at 250 VAC or 30 V DC—suitable for solenoids, lamps, and small contactors.
The relays default to the de-energized contact (NC) on power loss. Plan control logic accordingly for safety.
No—power down the Rnet segment before removal or insertion to avoid network errors.
Up to 64 total Rnet stations, mixing input, output, and relay modules, depending on PLC capacity.
Each channel has a green LED when energized and a red LED indicating fault or overload.
