ABB Freeland Hybrid Digital Input Module
This Digital Input Module features 16 digital inputs and the input voltage range is 18 to 30 Vdc. The inputs are divided into two isolated groups with eight channels and one voltage supervision input in each group. Every input channel consists of current limiting components, EMC protection, input state indication LEDs and an optical isolation barrier. The process voltage supervision input give channel error signals if the voltage disappears with the error signal can be read via the ModuleBus
Digital input PLC module is rated at 24 Vdc with a rated isolation of 50 V. Suitable for use with ABB's Freelance Hybrid process control system solutions. Used with module termination units TU810, TU812, TU814, TU830, TU833, TU838.
