Introduction

4.1.2 General Description

Weidmüller’s ACT20X – new signal converters for hazardous areas: Universal family of products covers the entire field of hazardous area applications with six different basic functions.

With the introduction of its ACT20X modules Weidmüller is offering a completely new family of signal converters for hazardous area applications. With just 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 "WIManager". This software is based on vendor-neutral FDT/DTM technology. The innovative 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 innovative 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. With high levels of insulation resistance, accuracy and thermal stability ACT20X modules provide a pure, disturbance free signal at all times. 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, IECEx, FM – in other words, the modules are predestined for use in applications all over the world.

Utilizing the "WI-Manager" configuration software based on FDT technology (Field Device Tool) makes it possible to adapt all ACT20X products via a PC to meet different process application requirements. For this purpose Weidmüller provides the Device Type Manager (DTM), which can be executed in any FDTbased frame application. As well as fast and errorfree parameterization of individual devices DTMs make it possible to evaluate measurement and diagnostic data. In addition, it is possible to unambiguously identify a connected device via DTM.

ACT20X modules are equipped with a cleverly designed connection technology that supports

simple, coded mating. The integrated release lever ensures the connection can be disconnected without damage when servicing is required. Devices from the ACT20X family have been designed to operate in an ambient temperature range of -20 °C to +60 °C – in other words in practically all fields of industry. The hinged and transparent front plate can easily be opened upwards. It has been designed for simple accommodation of device markers.

Products from the ACT20X assortment are designed to be installed in Zone 2 / Division 2 or in nonhazardous areas; international approvals such as ATEX, IECEx and FM (Class I, Division 1 and 2) allow processing of signals from Zone 0 / Division 1. Put succinctly, the modules are suitable for use in applications across the globe.

7.2 ACT20X-HTI-SAO (Temperature/mA Converter)

7.2.1 Description

The modules of the ACT20X-HTI-SAO family transmit analog signals galvanic isolated from hazardous areas to the safe area. The input circuits are designed intrinsically safe.

The ACT20X-HTI-SAO converts and isolates current and temperature sensor signals (mA, RTD and TC). The two-channel version ACT20X-2HTI-2SAO can be used as a signal splitter for mA signals.

For the higher accuracy of thermo couple signals, the use of special cold junction terminals ACT20X-CJCHTI-S recommended: 1160640000 ACT20X-CJC-HTI-S PRT 11 (1-channel) 1160650000 ACT20X-CJC-HTI-S PRT 21 (2-channel)

Features

Configuration and monitoring are performed via FDT/DTM Software "WI-Manager".

  The device can be mounted in the safe area and in Zone 2 / Division 2 and receive signals from Zone 0, 1,

2, 20, 21 and 22, as well as Class I/II/III, Division 1, Group A-G.

 The passive signal inputs for RTD, TC and mA are made for one or two channels and completely

electrically isolated.

 The two-channel version is suitable to use as a signal splitter.  3-way galvanic isolation between input, output and supply.  Front LEDs indicate operation status and malfunction.  The cold junction compensation for TC-signal inputs is either the internal cold junction compensation, or for

higher accuracy is an external cold junction compensation terminal available –- 1 channel 1160640000 ACT20X-CJC-HTI-S PRT 11 or 2 channel 1160650000 ACT20X-CJC-HTI-S PRT 21.
