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, a signal isolator and a high side output driver allowing you to combine all three functions into a single module.

Forming part of OMNIFLEX’ extensive OMNITERM range of industrial instrumentation, the OMNITERM LZB is designed to be DIN rail or surface mounted and is a space saving 22.5mm wide, or 11.25mm per channel.

See the companion Omniterm LZD datasheet for dual analogue inputs with surge protection.
