Omniflex has introduced three innovative new signal isolators, the Omniterm LZ series, with integrated surge protection to cater for applications that require joint isolation and surge protection. Typically high risk areas that are vulnerable to surges need both isolation and surge protection which requires two devices fitted to the field loop – the LZ series combines both functions in a single 22,5 mm wide package.
The OMNITERM LZI and LZD are current loop interface modules designed to interface field mounted transmitters in remote applications such as interfacing for RTUs and PLCs. The LZI is a single channel device with additional flexibility and support for both 2-wire and 4-wire 4–20 mA transmitters. The LZD is a dual channel device for increased packing density suitable for multiple 2-wire transmitters.
The OMNITERM LZB is a dual input field contact interface module designed to protect RTU and PLC installations from external factors such as lightning surges, ground loops and wiring faults. This module includes a fully specified surge arrestor and a high side output driver allowing users to combine all these functions into a single module.
These modules utilise advanced electronic techniques to achieve high accuracy and low power consumption with zero field calibration, saving on installation and commissioning time. Reliability figures in accordance with IEC61508 (SIL1) are available to allow inclusion of these devices in safety systems.
