NEIO-1103-S

4 Dual-Channel Safety Digital Input, SIL3 HFT=1 (IEC 61508), PL=e Cat.3 (ISO 13849-1)

Overview

NexCOBOT's NEIO-1103-S is a compact, palm-sized Safety Digital Input module that provides functional safety compatibility with SIL 3/HFT=1 and PL=e/Cat.3. The NEIO-1103-S adopts the Renesas RX series MCU and features 8 channels of digital input (4 dual-channel inputs with Cat.3 compatibility), designed to receive signals from external sensors or devices (Success Story with Renesas: NexCOBOT Co. Ltd. | Renesas). These received signals are subsequently transmitted to the Safety Controller via FSoE (Functional Safety over EtherCAT).
