You use intrinsically safe circuits in potentially explosive areas to limit power. For such purposes, you need intrinsically safe signal converters with electrical isolation and reliable components with lightning and surge protection to protect your sensitive sensors and prevent system failure.
We offer a complete packet of solutions for signal processing between your measuring instruments in the field and the I/O modules in the cabinet with perfectly compatible components; it consists of the slim, analogue ACT20X signal converter and the VARITECTOR SPC EX or VARITECTOR SSC EX surge protection module. .
The universal ACT20X signal converter with electrical isolation features an intrinsically safe input for HART® signals, DC, RTD, and thermal element or NAMUR signals from hazardous areas, and isolates them from safe areas. The electrical power in this 12.5 mm slim module is isolated from the input and output.
Approvals such as ATEX, IECEx, cULus Ex, FM, GOST and DNV ensure that it can be used around the globe.
The VARITECTOR SPC EX and SSC EX (slim variant) modules offer the option of safely discharge power surges in the hazardous zones (1 or 2). The pluggable arresters in the VARITECTOR SPC EX meet the tough requirements for intrinsic safety in hazardous areas in accordance with the current EN 60079 standard. They comply with the IEC 61643-21 product standards and are tested for protection classes D1, C2 and C1.
