PLCs, Power Supplies & Others

The Honeywell 10106/2/1 functions as a fail-safe, line-monitored digital input module for critical safety applications. This unit reliably acquires signals from field devices in emergency shutdown (ESD), fire & gas (F&G), and interlock systems. Consequently, it securely transmits status information from switches, relays, and alarms to the control system.

Core Technical Specifications

We engineered the Honeywell 10106/2/1 for SIL2/SIL3 safety compliance, ensuring dependable operation in the most critical safety functions. The table below details its essential physical and electronic parameters:

Fail-Safe Design for Safety Applications

The 10106/2/1 incorporates fail-safe circuitry that defaults to a safe state under fault conditions. This design ensures that any module failure results in predictable, safe outputs for the process. Therefore, it meets the stringent requirements of emergency shutdown and fire & gas systems.

Line Monitoring for Continuous Integrity Checking

Built-in line monitoring continuously checks the wiring integrity of each input channel. It detects open circuits, short circuits, and ground faults on field wiring. Consequently, operators receive immediate alerts if a field device or its wiring becomes compromised.

16 Independent Channels with High Isolation

This module features 16 fully independent digital inputs with greater than 1500 VAC channel-to-channel isolation. This high isolation prevents faults on one channel from affecting others, ensuring system integrity. As a result, you achieve reliable signal acquisition even in electrically noisy environments.

Flexible Input Type Configuration

You can configure each channel to accept either dry contact closures or 24 VDC field signals. This flexibility allows connection to a wide variety of safety devices without external signal conditioning. Hence, the Honeywell 10106/2/1 adapts to diverse field device requirements.

Fast Response for Critical Events

With a response time of less than 10 milliseconds, the module reacts quickly to changing field conditions. This speed ensures that the safety system detects and responds to events without unnecessary delay. Therefore, it supports the fast reaction times required for SIL-rated functions.

Wide Environmental Tolerance for Global Deployment

The module operates reliably across a broad temperature range of -20°C to +60°C. It also withstands storage extremes from -40°C to +85°C and high humidity levels. Consequently, you can deploy the 10106/2/1 in diverse climates and environments without special protection.

SIL2/SIL3 Certified for Safety Integrity

Honeywell designed this digital input module to meet SIL2 and SIL3 safety integrity level requirements. It complies with CE standards and international safety norms for critical applications. As a result, you can use it in safety-instrumented functions demanding the highest reliability.

Versatile Mounting Options

You can install the module on standard DIN rails or in rack-based systems for flexible cabinet integration. This versatility allows for straightforward installation in both new projects and retrofit applications. Hence, it suits a wide range of safety system architectures.
