IMO/LS Electric GDL-DT4C1 – 16 Inputs & 16 Outputs DeviceNet Smart I/O Module (20.4 – 28.8 V DC)
IMO GDL-DT4C1 is a DeviceNet Smart I/O module combining 16 NPN/PNP-compatible digital inputs with 16 NPN sinking transistor outputs rated at 0.5 A per channel for distributed industrial automation.
Why Choose the IMO GDL-DT4C1 DeviceNet Smart I/O Module?
The IMO GDL-DT4C1 is a compact DeviceNet Smart I/O module designed for distributed industrial automation and machine control. It combines 16 digital DC inputs with 16 NPN transistor outputs, providing 32 integrated digital I/O points for connecting sensors, switches, actuators and other field devices to a DeviceNet network.
The GDL-DT4C1 accepts NPN and PNP digital input signals and provides 16 sinking NPN transistor outputs rated at 0.5 A per output. Its I/O system operates from a nominal 24 V DC supply, making it well suited to standard industrial control equipment and field instrumentation.
Designed as a standalone distributed I/O device, the GDL-DT4C1 allows field signals to be positioned closer to machinery while I/O data is exchanged with the controller through DeviceNet. A detachable terminal block simplifies field wiring and servicing, while response times of 3 ms or less support responsive machine-control applications.

Distributed DeviceNet I/O with NPN Transistor Outputs
Distributed I/O allows sensors and actuators to be connected close to the machinery they serve rather than routing every field connection directly back to a central control cabinet. The IMO GDL-DT4C1 combines 16 digital inputs and 16 transistor outputs with DeviceNet communications, providing a compact interface between field equipment and a compatible industrial controller.
The GDL-DT4C1 is the NPN output version of the GDL-DT4C family. Its inputs accommodate both NPN and PNP devices, while its outputs use an NPN sinking configuration. This distinction is important when selecting the module for existing machinery, as connected output loads must be electrically compatible with sinking transistor control.
Typical Applications
- DeviceNet distributed I/O systems.
- Industrial machinery and production equipment.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- 24 V DC sensor and actuator interfacing.
- Machine control systems using NPN sinking outputs.
- Factory automation and decentralised control panels.
