DI3361 TRICONEX

1. Product Description

The DI3361 from TRICONEX is a high-integrity digital input module designed for use within their Safety Instrumented Systems (SIS). As a critical component of the TRICONEX platform, the DI3361 provides reliable and fault-tolerant acquisition of discrete (on/off) signals from field devices in safety-critical applications. This specific DI3361 model is engineered to meet the stringent demands of SIL (Safety Integrity Level) rated systems, ensuring accurate and dependable input data for safety logic processing. Its core function involves receiving digital signals from devices such as limit switches, pressure switches, and emergency stop buttons, and converting them into digital data that can be processed by the TRICONEX controller to execute safety functions. The DI3361 is built for continuous operation in harsh industrial environments and contributes significantly to the overall safety and availability of industrial processes by providing reliable input data for critical safety decisions.

2. Product Parameters

Given its essential role in safety systems, the technical parameters of the DI3361 TRICONEX digital input module are heavily focused on reliability and safety integrity. Typical parameters include:

Parameter	Description
Input Channels	Specifies the number of independent digital input channels available on the module (e.g., 32 channels).
Input Voltage Range	The range of input voltages that the module can safely and accurately detect as a logic high or low (e.g., 24V DC).
