FUNCTIONAL DESCRIPTION:

IS230TNCIH1C is a Simplex Contact I/O DIN-Rail Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Simplex Contact I/O DIN-Rail Module is a digital input/output interface module designed for use in industrial automation and control systems. It provides discrete contact signal interfacing for applications requiring reliable on/off status monitoring and control. The module supports both input and output contact channels, enabling it to monitor field device statuses (such as switches, relays, and limit sensors) and control actuators (such as solenoids or contactors). It is built for DIN-rail mounting and integrates with programmable logic controllers (PLCs), distributed control systems (DCS), and other I/O platforms through standard communication buses or terminal blocks.

INSTALLATION:

The module is designed for quick and secure installation on standard 35 mm DIN rails within control cabinets or panels. Before installation, ensure that all system power is turned off to prevent electrical hazards. Mount the module onto the DIN rail by sliding it into place until it locks securely. Connect field devices to the input and output terminals as per the wiring diagram provided in the manufacturer’s documentation. Signal and power cables should be properly labeled, routed, and shielded to minimize electrical noise. Grounding must be done according to system requirements to ensure safe and stable operation.

OPERATION:

The Simplex Contact I/O DIN-Rail Module detects the open or closed state of externally connected input contacts and converts these discrete signals into logic-level inputs for the control system. Each input channel monitors contact closures using either dry contact sensing (voltage-free) or wet contact sensing (voltage-present), depending on the system configuration. For output functions, the module switches discrete control signals to actuate field devices, such as relays or solenoids, as directed by the central controller or PLC. The module incorporates opto-isolation and noise filtering to ensure signal integrity. Channel status is typically indicated by onboard LEDs, allowing for visual verification during operation and diagnostics. The module is designed for fast response times to support time-critical control applications and operates reliably under industrial conditions, including electrical noise, temperature variations, and vibration.

SUSTAINABILITY:

The Simplex Contact I/O DIN-Rail Module is built with durability and long-term performance in mind. It uses industrial-grade components rated for extended operational life and wide temperature ranges. Low power consumption and robust design contribute to reduced maintenance and system downtime. The module’s housing is made from recyclable materials where possible, and it complies with environmental and safety standards such as RoHS and CE. Its modular design also allows for easy replacement or upgrade without a full system overhaul, supporting sustainability goals in control system life cycle management.

COMPATIBILITY:

The module is compatible with a variety of industrial control systems, including PLCs, SCADA systems, and DCS platforms from major manufacturers. It supports standard 24VDC digital I/O signaling and can interface with both sinking and sourcing configurations depending on system requirements. Communication with the host system may occur via terminal block wiring or via bus interface modules, depending on the model. The module integrates easily into existing systems and is suitable for both new installations and retrofits, ensuring broad applicability in industrial and utility automation.

FREQUENTLY ASKED QUESTIONS:

What is the function of the GE Simplex Contact I/O DIN-Rail Module?

The module is used to interface discrete (ON/OFF) field signals with the GE Mark VI or Mark VIe control systems. It monitors input contact states and sends logic signals to the controller, and also controls external devices by switching outputs.

What type of outputs are supported?

The module typically uses solid-state sourcing outputs capable of driving DC loads such as relays, indicators, and solenoids. Each output channel supports up to 0.5 A at 24 VDC.

What is the isolation rating between the field and logic side?

The module provides galvanic isolation rated at 1500 V RMS between field wiring and internal logic circuits. This protects the controller from voltage spikes and ground loops. Channel-to-channel isolation prevents interference between adjacent I/O points.

What is the maximum current capacity of each output channel?

Each output channel can continuously source up to 0.5 A at 24 VDC, suitable for typical industrial loads. Internal protection limits the current to prevent damage. Total current across all outputs must stay within system power and thermal limits.
