2 Available in configurations that accept a variety of inputs, the principal function of the ECT family of products is to provide low cost isolation (up to 1500 Vrms) between instruments at either end of a process loop. Additionally, some ECT configurations perform signal conversion. They accept either dc or ac voltages and provide a precise, industry-standard 4-20mA output. The ECT is a highly cost-effective means of protecting process signals from distortions associated with ground loops, motor noise and other common types of ambient electrical CT/PTSPANZERO+PS PS4-20mA10-50mA1-5V0-10V0-150AC0-250AC0- 5 AAC4-20mA10-50mA1-5 VOptionsThere are several options available for the ECT: EM Externally Mounted Transformer, for use with the 0-5 Aac input configuration, this option consists of a toroidial transformer that physically separates high-level current input from the receiving device in a process loop.

3 This provides the added convenience of allowing the servicing of receivers without having to interrupt process signals. RF RFI/EMI Protection, available for use with our new aluminum housings, this option provides you with outstanding protection against RFI and EMI interference. (requires -EM option for ac current input). With this option, the ECT will not be affected by more than of span at 30 V/m @ 1.

10 Every product Moore Industries manufactures, sells and services is guaranteed to meet the strict quality standards that have become synonymous with our company placing your ECT into service, a bench check of basic operation is recommended to ensure that the unit hasn t sustained any damage during transit, and to set zero and span for your unit should be: Checked to verify that the appropriate ECT model has been ordered for the intended application. Connected in a calibration setup (described later in this section) and checked for desired output. Adjusted for desired zero and SetupTable 1 lists the equipment you will need to bench check the ECT.
