Product Description

The SHS20C safety switch integrates 2 digital inputs and 1 NO/NC output, designed for machine safety interlocks with IP65 protection. It directly interfaces with up to 4 safety modules via dual-channel redundancy, supporting 10-30VDC operation (-20°C to +55°C). The SHS20V voltage sensor monitors 0-1000V AC/DC systems through isolated analog inputs (24-bit resolution), featuring 3 configurable relay outputs and RS-485/Modbus communication for grid/industrial applications. Its 0.5% accuracy suits energy management in harsh environments (IP54, -25°C to +70°C). The SHS20R relay module provides 8 configurable SPDT contacts (5A@250VAC each) with galvanic isolation, controllable via 4 opto-isolated inputs and Ethernet/IP interface. All variants employ rugged housing with EMC immunity, enabling flexible cascade connections across 15m via shielded cables. Critical limitations include mandatory use of external suppressor diodes for inductive loads (SHS20R) and restricted ambient temperatures beyond specified ranges.
