Loop-powered Signal Isolator from Weidmuller
Richmond, VA — Weidmuller has introduced a new configurable loop-powered signal isolator — the ITXPlus. This compact new signal conditioner provides complete electrical isolation and is suitable for control system applications with a mix of inputs. It can measure, filter and isolate different input parameters, then convert them into an industry standard 4-20mA output.
With this unusual capability and slim profile, the isolator offers savings on both I/O wiring and panel space. the company's new product is highly flexible because it can be programmed to suit a full range of common analog signals and sensor types, such as PT100, thermocouple, mV, mA, voltage, resistance and potentiometer inputs. The isolator can set 4-20mA output as either direct or reverse action. The output configurability of the ITXPlus provides users with the ability to define specific characteristics based on application needs. These specific characteristics include square root, linear and X
transfer functions. The signal isolator offers built-in functionality for applications that require temperature measurements. Its output can be configured to represent virtually any temperature range within the
characteristic of all industry standard thermocouples and RTDs (Resistance temperature detectors). The unit also offers selectable upscale or downscale sensor-break response. The transmitter can process signals from other non-linear resistance devices, such as an NTC, PTC or log potentiometer, providing added value across numerous applications.
In addition, the ITXPlus has a user-definable, user-programmable characteristic table that contains up to 101 measurement values. This is especially helpful when measuring levels with non-linear tank shapes. Measurements are delivered with excellent accuracy making it suitable for virtually all process instrumentation applications.
If a sensor is replaced the isolator can be easily re-configured with the user-friendly configuration software (TSET), which runs on any PC or laptop. Users can even connect and reconfigure the ITXPlus while it is in active operation, preventing costly system downtime. The configuration file can then be saved and printed for each serial or tag number as a back up or for future reference. The software also permits easy ITXPlus data logging onto the PC.
The unit is 12.5mm wide in a compact and space-saving design. It is DIN-rail mountable and cULus approved.
