The MK33-111EXO-HLI24VDC is a safety barrier of the Turck brand, mainly used for signal isolation and transmission in hazardous areas of industrial automation. The following is its detailed description:
- Number of Channels: 2 channels
- Signal Type: Supports digital input, and can be connected to NAMUR sensors, variable resistors or mechanical contacts that comply with the EN 60947-5-6 standard
- Output Type: The output circuit consists of two relays, each with one normally open contact; the output mode can be selected between normally open/normally closed modes
- Isolation Characteristics: Complete electrical isolation between input, output circuits and power supply, improving the safety and anti-interference ability of signal transmission
- Power Supply Voltage: 24V DC
- Intrinsically Safe Input Circuit: Complies with the EEx ia standard
- Mounting Method: DIN rail mounting, with a width of 18mm
- Protection Rating: IP20
- Operating Temperature Range: Not explicitly stated, but usually, such Turck products have an operating temperature range of approximately -25℃ to +70℃
- Certification Status: Certified by FM, NEPSI, etc.; can be installed in hazardous Zone 2; application fields are {Ex ia} IIC/IIB and Ex nA nC {NL} IIC/IIB T4
- Equipped with pluggable terminals for easy wiring and maintenance
- Has a signal grouping function, enabling synchronous control of multiple devices
- Two yellow LED indicators can display the on-off status of the corresponding output relays, facilitating real-time monitoring.
