The excellent cost/performance ratio presents many new and exciting opportunities without compromising quality or reliability. Output voltage Adjustment range Output current The mechanically robust housing is made of a highgrade, reinforced molded material, which permits the units to be used in surrounding temperatures up to 70°C. The unit is equipped with a wide-range input voltage stage, which makes the unit suitable for global use. The addition of a DC-OK signal makes the unit suitable for many industry applications such as: process, automation and many other critical applications where preventive function monitoring can help to avoid long downtimes.
