GM International D5290S/SA 1-Channel SIL 3 Relay Output Module 24VDC

The GM International D5290S/SA is a 1-channel SIL 3 relay output module that may switch safety-related circuits in high-risk industrial settings. It uses a 24 VDC control input to drive high-power NE loads up to 10 A. It separates the input and output circuits with galvanic isolation and has separate NO power connections and a service NC contact to make sure that shutdown and maintenance are safe.

The D5290S/SA is a single-channel relay output module that can be safely installed in a safe location. It is meant to manage Normally Energized (NE) loads in functional safety loops up to SIL 3 according to IEC 61508. It has a nominal input of 24 VDC and strong relay contacts rated at 10 A at 250 VAC / 250 VDC, making it perfect for driving contactors, solenoids, alarms, and other power devices used in safety interlock (ESD), interlocking, and emergency shutdown (ESD) systems.

The module has one SPDT relay contact that gives a primary NO output and a service NC output. It also has an extra NO contact that lets you terminate the load on both supply lines for optimal safety. It is a strong choice for process, oil and gas, chemical, power, and general industrial automation systems since it has input/output isolation, EMC compliance, a wide working temperature range, and a small 22.5 mm DIN-rail housing.

Features of D5290S GM International:

1) This SIL 3 relay output module is for safety-related circuits in high-risk industries. It meets IEC 61508 standards and works with NE load topologies.

2) 1-channel 24 VDC input that is safeguarded against reverse polarity. It uses roughly 40 mA of current and loses about 1 W of power at 24 V.

3) High-power relay contacts can handle up to 10 A at 250 VAC / 250 VDC (resistive), and they can handle 16 A of inrush current for heavy inductive or motor loads.

4) Two NO outputs and one service NC contact (SPDT + SPST) let you disconnect both supply lines and provide a non-SIL service indicator or extra load.

5) This small DIN-rail module has an IP20 casing, plug-in terminal blocks, and a wide range of operating temperatures, from -40 °C to +70 °C, making it suitable for tough industrial settings.

Output / Relay Specifications

Isolation and Protection

Typical Application:

-> In oil and gas, petrochemical, and process plants that need SIL 3-rated relay outputs for NE loads, there are emergency shutdown (ESD) circuits and safety interlocks.

-> Control of safety-critical actuators like alarms, valves, solenoids, and contactors, where the load must be turned off to reach a safe state.

-> Extra shutdown paths and dual-line disconnection techniques that need both supply lines to the load to be opened when there is a trip condition.

-> Safe-area interface modules in distributed control systems (DCS), PLC safety systems, and relay panels that need galvanic isolation between 24 VDC control signals and high-power field loads.
