imo grl-d22a plc smart i/o 20.4-28.8vdc

Why Choose the IMO GRL-D22A Rnet Smart I/O Module?

The IMO GRL-D22A is a compact Rnet Smart I/O digital input module designed for distributed industrial automation and machine control systems. It provides 16 digital DC inputs in a single remote I/O unit, allowing switches, proximity sensors, photoelectric sensors and other discrete field devices to communicate with a compatible Rnet control system.

The GRL-D22A is designed for 24 V DC input signals and supports sink/source input wiring, providing flexibility when connecting common industrial sensors and switching devices. All 16 input points share a common terminal, creating a straightforward high-density interface for collecting discrete machine and process signals.

As part of the Smart I/O family, the GRL-D22A communicates through Rnet and uses a fixed terminal block for field wiring. With an input response time of 3 ms or less and low module current consumption, it provides a practical distributed I/O solution for compatible industrial automation installations. The associated product code is 47060001.

Compact Digital Input for Rnet Automation

Distributed I/O allows industrial sensors and switches to connect to an I/O station positioned closer to the machinery or process, reducing the need to route every discrete field signal directly back to a central PLC cabinet. The IMO GRL-D22A provides 16 digital input points over Rnet, making it suitable for collecting machine status and sensor information within compatible distributed control architectures.

The module's 16 inputs are arranged on a single common and support standard sink/source 24 V DC field signals. Combined with fast input response, fixed terminal connections and low current consumption, this makes the GRL-D22A suitable for limit switches, proximity sensors, machine interlocks and other discrete monitoring functions.

Typical Applications

• Rnet distributed I/O systems.
• Industrial machinery and production equipment.
• Conveyor and material handling systems.
• Packaging and processing machinery.
• Limit switch and proximity sensor monitoring.
• Machine status and interlock signals.
• Factory automation and distributed control panels.
• 24 V DC discrete sensor interfacing.
