Intrinsically Safe Modules with Improved Features and New Functions
WAGO has streamlined and expanded its range of Ex i modules. The new 8-Channel Digital Input Module (750-439/040-000) for intrinsically safe digital applications (8DI NAMUR Ex i) can now also connect break contacts and their signals in addition to NAMUR make contacts. Furthermore, the new module can record them in accordance with the IEC 60947-5-6 standard. Because they can be used to detect typical sensor failures such as wire breaks, break contacts’ role in process technology is becoming more and more important. NAMUR make or break contacts are defined channel by channel via the process image for 8DI NAMUR Ex i.
The new 4-Channel Analog Input Module (4AI RTD/TC/Strain Gauge Ex i; 750-489) complements the analog portion of WAGO’s portfolio. It combines the functionality of proven modules with enhanced characteristics. The module offers double the number of channels, which are now electrically isolated. It also provides higher resolution, faster conversion time, fewer measurement errors and the combination of RTD and TC functions in one module. One of the new module’s advantages is that signals from resistor bridges – such as strain gauges – from zone 0 and 1 hazardous areas can now be measured directly.
The Benefits for You:
- More applications and reliable wire break diagnostics with 8DI NAMUR Ex i
- 4AI RTD/TC/Strain Gauge Ex i processes signals safely, quickly and without errors, acquires measured values precisely and requires only a small amount of space.
