Curtiss-Wright / Systran DID48-68 48-Channel, Debounced Discrete Input IP Module

The Curtiss-Wright/Systran DID48-68 is a 48-channel debounced discrete input IP module engineered for industrial control and digital signal monitoring applications. Integrated debouncing circuitry filters electrical noise and switch bounce to deliver clean, accurate data acquisition from discrete sensors and contact closures. Network connectivity via Ethernet enables direct integration into distributed control architectures without external signal conditioning hardware.

## Technical Specifications

• **Channels:** 48 discrete input channels
• **Input Type:** Debounced digital inputs with integrated signal conditioning
• **Network Interface:** Ethernet (RJ45); TCP/IP protocol suite
• **Application Protocols:** Supports Modbus TCP, EtherNet/IP, and proprietary protocols
• **Input Connectors:** Terminal blocks or industrial-grade connectors (configuration per module variant)

## Key Features

• Integrated debouncing eliminates spurious signals from switch bounce and electrical noise
• Channel-to-channel and channel-to-ground isolation prevents ground loops and protects against voltage transients
• IP-based architecture enables networked deployment across distributed systems
• DIN rail or panel mounting options for flexible enclosure integration
• Industrial-grade environmental ratings suitable for harsh operating environments

## Typical Applications

• Discrete sensor monitoring in automated manufacturing systems
• Industrial control logic and supervisory systems
• Safety-critical discrete input acquisition where signal integrity is mandatory
• Networked discrete I/O consolidation in multi-site control architectures

## Compatibility & Integration

The module integrates directly into TCP/IP-based industrial networks. Ethernet connectivity supports standard industrial protocols including Modbus TCP and EtherNet/IP, enabling interoperability with established control platforms and SCADA systems. Discrete input voltage thresholds, input current draw per channel, and isolation voltage ratings are detailed in the product manual. Power requirements and detailed environmental specifications (operating/storage temperature, humidity) are provided in technical documentation.
