Information About 2865984
The 2865984 is part of the MACX ANALOG EX series, a family of signal conditioners engineered for explosion-protected environments and functional safety applications. The module uses a compact DIN-rail-mounted housing with screw terminals and provides 3-way electrical isolation for stable, interference-free signal transmission. It is compatible with NAMUR proximity sensors, floating contacts, and resistive contact circuits, offering selectable direction of operation and configurable LFD behavior. Typical industrial uses include monitoring sensor signals in ATEX/IECEx environments, relay-based process control, and safe signal transmission across intrinsically safe circuits.
Key Features:
- 2-Channel NAMUR Input: Supports NAMUR proximity sensors and switch contacts.
- Ex-i Intrinsic Safety: Suitable for hazardous-area installations requiring explosion protection.
- Wide-Range Power Supply: Operates from 24 to 230 VAC/DC for flexible deployment.
- Relay Outputs: Each channel includes a PDT relay contact for signal output.
- Line Fault Detection: Detects open/short circuit conditions with LED indication.
- 3-Way Electrical Isolation: Ensures interference-free signal transfer between input, output, and supply.
- SIL 2 Functional Safety: Certified for applications requiring safety integrity level compliance.
- DIN-Rail Mounting: Compact design for efficient panel integration.
The 2865984 delivers the reliability and precision required for hazardous-area signal isolation and NAMUR sensor interfacing.
