Product Description
It adds four wide-range digital inputs that accept signals from 0 to 250 V AC/DC, making it suitable for both low-voltage control signals and industrial mains-level inputs. Each channel is electrically isolated from the others, which improves signal integrity and simplifies mixed-voltage wiring. The module clips onto a DIN rail with screw termination and a supplied DIN rail connector for bus continuity. It supports hot-swap replacement during operation and is approved for use in ATEX Zone 2 installations. With an extended -40 to +70 degrees C range and thumbwheel-based startup, it is designed for demanding process and utility environments. The Phoenix Contact 2901535 is part of the Radioline family of wireless and wired I/O modules and functions as a digital input extension module.
