About EHS 2042 Pressure Switches:
The EHS 2042 module range provides the universal interface between signal and output levels in industrial controls. The modules are designed to combine operational unit and terminal strip into one. In addition to their operational tasks, i.e. amplification of computer control signals, they also offer isolation from the unit to be controlled, which enhances the construction of the interference free robust controls. Each module can operate independently from a simple DC supply.

Features:
• Compact construction.
• Replaces terminal strips
• Module can be fitted to standard DIN rails
