Overview
The document provides detailed information on IDEC's EB3C Relay Barriers, which are intrinsically safe and explosion-proof. These barriers are designed for use in hazardous areas and comply with IEC60079 standards. They are suitable for global use, with certifications from FM, CSA, CE, ATEX, and others.

Specifications
The EB3C Relay Barriers offer explosion protection with a degree of protection rated at IP20. They support both AC and DC power, with universal AC power voltage ranging from 100 to 240V AC. The barriers do not require grounding and feature IDEC’s original spring-up terminals to minimize wiring time. Installation options include 35-mm-wide DIN rail mounting or direct panel mounting.

Electrical Specifications
The barriers support a maximum voltage of 250V AC/DC for non-intrinsically safe circuits and have specific ratings for intrinsically safe circuits, including a maximum output voltage of 13.2V DC and a maximum output current of 14.2 mA. The barriers are designed to handle various load types, with specific ratings for resistive and inductive loads.

Certifications
The EB3C Relay Barriers are certified for use in hazardous locations by several organizations, including FM, CSA, NEMKO, and TIIS. They are approved for use in Class I, II, III Div. 1 Group A, B, C, D, E, F, G environments.

Part Numbers and Accessories
The document lists various part numbers for different configurations of the EB3C Relay Barriers, including options for relay and transistor outputs. Accessories such as DIN rails and mounting clips are also available.

Wiring and Installation
Detailed wiring examples are provided for different output types, including transistor sink and source outputs, as well as relay outputs. The document includes diagrams for internal circuit blocks and external wiring setups.

Dimensions
Dimensions and mounting hole layouts are provided for various models of the EB3C Relay Barriers, ensuring proper installation and compatibility with existing systems.
