Why Choose the IMO GSL-RY2C Smart I/O Relay Output Module?
The IMO GSL-RY2C is a compact and reliable 16-point digital relay output module designed for distributed industrial automation and remote I/O applications. As part of the IMO Smart I/O series, it provides relay-based output switching with Modbus RTU communications over RS-422/485, enabling straightforward integration with PLCs, controllers and industrial automation networks.
The GSL-RY2C combines 16 relay outputs with convenient removable terminal blocks, simplifying installation, wiring and maintenance within industrial control panels. Its distributed I/O architecture allows output switching to be positioned closer to field equipment, helping reduce extensive point-to-point wiring between machinery and the main control system.
Operating from a 20.4–28.8 V DC supply, the GSL-RY2C provides 16 relay outputs rated at up to 2 A per output, with a maximum load of 5 A per common. Its relay contacts can be used with both DC and AC loads, making the module suitable for controlling contactors, solenoids, indicators, alarms and other industrial devices.

Reliable Relay Control for Distributed Automation
Remote I/O modules such as the IMO GSL-RY2C allow electrical outputs to be positioned closer to machinery and field devices while remaining under the control of a central PLC or automation controller. Communication over an RS-422/485 Modbus network reduces the amount of individual field wiring required and provides a practical method of expanding automation systems across larger machines and installations.
The GSL-RY2C uses relay outputs rather than semiconductor transistor outputs, providing flexible switching for compatible AC and DC loads. Its removable terminals are particularly useful in industrial installations where fast wiring, servicing or module replacement is important, while its output indication assists engineers with commissioning and fault diagnosis.
Typical Applications
- Distributed industrial I/O systems.
- PLC and Modbus-based automation networks.
- Industrial machinery and production equipment.
- Remote switching of contactors and control relays.
- Solenoid valves and actuator control.
- Industrial indicators, alarms and signalling devices.
- Conveyor and material handling systems.
- OEM machinery and control-panel applications.
