imo gpl-d24a plc smart i/o 20.4-28.8vdc

Why Choose the IMO GPL-D24A PROFIBUS-DP Smart I/O Module?

The IMO GPL-D24A is a compact PROFIBUS-DP Smart I/O digital input module designed for distributed industrial automation and machine control systems. It provides 32 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 PROFIBUS-DP master.

The GPL-D24A is designed for 24 V DC input signals and supports sink/source field wiring. Its 32 input points are arranged across two 16-point common groups, providing a high-density solution for applications requiring numerous discrete input signals without installing conventional I/O directly beside the central PLC.

As part of the Smart I/O family, the GPL-D24A communicates through PROFIBUS-DP, allowing decentralised field signals to be integrated into compatible PLC and automation architectures. The fixed-terminal design combines network communications, power and field connections in a compact industrial module measuring approximately 176.6 × 50 × 39 mm.

High-Density Digital Input for PROFIBUS-DP Automation

Distributed I/O allows industrial sensors and switches to connect to an I/O station positioned closer to the machine or process, with their status communicated to the controller over a fieldbus. The IMO GPL-D24A provides 32 digital input points over PROFIBUS-DP, making it particularly useful where a large number of discrete field signals need to be collected efficiently.

The 32 inputs are divided into two groups of 16 points per common and accommodate standard 24 V DC industrial signals. This arrangement makes the GPL-D24A suitable for machine status monitoring, limit switches, proximity sensors and other discrete input applications within compatible PROFIBUS-DP control systems.

Typical Applications

• PROFIBUS-DP 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 remote control panels.
• 24 V DC discrete sensor interfacing.
