Product Overview
The 2361 is a high-reliability Digital Input (DI) module specifically engineered for the Tricon Triple Modular Redundant (TMR) safety system. This module serves as a critical interface for 32 discrete 24 VDC field signals, such as limit switches, pushbuttons, and sensor contacts. Employing three independent processing paths, the module ensures that every input signal is cross-checked and voted upon at the hardware level. Its robust electrical design provides superior immunity to electromagnetic noise typical of industrial environments. The 2361 is an essential building block for plant operators seeking SIL 3 certified protection for their most critical assets.
Core Technical Functionality
-
Triple Modular Redundancy: Utilizes three isolated internal legs that synchronize and vote on all 32 input channels to eliminate single points of failure.
-
Redundant Power Paths: Independent power feeds from the chassis backplane ensure continued operation if one power bus fails.
-
Input Conditioning: Filters out contact bounce and electrical transients to provide clean, reliable data to main processors.
-
Galvanic Isolation: High-voltage isolation between field-side wiring and system logic protects the controller from external surges.
-
Self-Diagnostic Coverage: Performs background tests on internal components to identify and report latent hardware faults instantly.
-
Hot-Swap Capability: Supports live module replacement without interrupting active safety logic or process control.
Industrial Application Scenarios
The 2361 is widely deployed in high-consequence industries where process uptime and safety are critical:
-
Petrochemical: Interfaces with Emergency Shutdown (ESD) pull-stations and valve position switches.
-
Chemical Manufacturing: Monitors critical interlocks within Burner Management Systems (BMS).
-
Oil & Gas Offshore: Tracks fire and gas detector states across distributed hazardous zones.
-
Legacy DCS Modernization: Provides a high-density input solution when cabinet space is limited.
