Honeywell SDI-1624 CCV1.1 Secure Digital Input Module

The Honeywell SDI-1624 CCV1.1 is a high-performance, secure digital input module designed for use in industrial automation and safety systems. Part of the Experion® PKS ecosystem, this module provides 16 channels for interfacing with discrete field devices, such as limit switches, pushbuttons, proximity sensors, and relay contacts. It is engineered for reliable signal acquisition in both standard process control and safety-related applications

Designed for Reliability and Safety

The SDI-1624 CCV1.1 incorporates features that enhance system reliability and safety. Its robust design ensures stable operation in electrically noisy industrial environments. The module supports real-time monitoring of input states, allowing the control system to react immediately to process events or safety demands. Built-in protection mechanisms, such as short-circuit and over-voltage protection, safeguard the module and the system from field wiring faults

Key Features and Benefits

• 16 High-Density Channels: Allows for efficient monitoring of multiple discrete signals in a single module, saving cabinet space

• Flexible Input Types: Configurable to accept both dry contact (passive) and 24V DC voltage (sourcing) inputs, accommodating a wide range of field devices

• Built-in Protection: Features output current limiting to protect against overloads and short circuits, enhancing system robustness

• Comprehensive Diagnostics: Provides module-level and potentially channel-level diagnostics for quick troubleshooting and reduced downtime.

• Seamless Integration: Designed for direct integration with Honeywell Experion PKS, simplifying configuration and data mapping.

• Wide Operating Temperature: Suitable for use in harsh industrial environments, with an operating temperature range up to 70°C

Technical Specifications

Integration and Configuration

The SDI-1624 CCV1.1 mounts into a compatible Honeywell I/O chassis (e.g., IOCHAS-0001S) and is managed by an interface module like the IO-0001. Configuration is performed within the Experion engineering environment, where each channel can be named, assigned to logic, and have its input type and filter settings defined. The module's status is continuously available to the control system for monitoring and alarming.

Typical Applications

This versatile digital input module is used across many industries:

• Monitoring safety devices (e.g., emergency stops, safety gates, light curtains).

• Acquiring equipment status (e.g., motor run/stop, valve open/closed).

• Interfacing with pushbutton panels and selector switches.

• Connection with discrete sensors for level, flow, and position.

• Use in both basic process control and safety instrumented functions.
