HIMA KFD2-STC4-Ex1
1. Overview
HIMA KFD2-STC4-Ex1 is an intelligent transmitter power supply, specifically designed for hazardous areas (Ex areas). It is used to power 2-wire or 3-wire intelligent transmitters and supports the HART communication protocol. Its core function is to transmit analog signals from hazardous areas to safe areas while enabling bidirectional transmission of digital signals. This device complies with international safety standards (such as SIL 2 certification) and is suitable for the industrial automation field, widely applied in signal processing and transmission in explosion-proof areas.
2. Parameters
- Dimensions and Weight: The dimensions are 20×124×115mm, and the weight is approximately 200g.
- Protection Class: It has an IP20 protection class, making it suitable for installation in explosion-proof areas.
- Electrical Parameters:Electrical Isolation: Complies with the EN 50178 standard, with a basic insulation voltage of 50V AC.
- Input signal range: 0-20mA
- Output signal range: 0-20mA
- Supports HART communication
- Environmental Conditions: The operating temperature range is -20°C to 60°C, and it complies with the EN 60079-11 standard.
3. Product Features
- Single-channel Design: Simplifies installation and maintenance, and reduces costs.
- Explosion-proof Area Application: Suitable for explosion-proof Zone 2 (areas where explosion risks exist but are not persistent).
