With the introduction of its ACT20X modules Weidmüller is offering a family of signal converters for hazardous area applications. With 11 mm per channel these compactly designed modules require very little space in the electrical cabinet. All ACT20X converters can be configured via a PC utilizing the software ‘WI-Manager’. This software is based on vendor-neutral FDT/DTM technology. The modules are designed to be installed in safe or hazardous areas of Zone 2. The ACT20X family includes digital and analogue intrinsically safe converters that both isolate and convert signals from as well as into hazardous areas. The signal converters process 2-wire HART, NAMUR, RTD, thermocouple or DC signals as well as digital signals with electrical connection to hazardous area Zone 0. All modules have 3-way separation and are optionally available with dual channel functionality. A relay-based error monitoring facility simplifies servicing. ACT20X modules can be utilized in temperatures from -20 °C to +60 °C without restrictions. They have all relevant international approvals such as ATEX, ICEEX, GOST, FM.
