Installation Guide

1. Mount on DIN EN TS32/TS35 x 7.5 rail (196 mm required).
2. Wire field loads to screw terminals (max 2.5 mm², torque 0.5 Nm).
3. Connect SICC cable to corresponding digital output module.
4. Verify fuse integrity and contact operation per channel.

Selection Tips

• Match contact rating to load requirements (inductive/resistive).
• Account for derating: 5 A at 25°C to 3.5 A at 70°C.
• For safety loops, verify SIL compatibility with system architecture.
