DUO-TOUCH SG Safety Module and STB Optical Touch Button Manual

This document describes the DUO-TOUCH SG safety module and STB Self-Checking Optical Touch Button, which together form an ergonomic, self-checking two-hand-control system for machine operator hand protection. The system uses diverse-redundant microcontrollers and force-guided output contacts to verify proper operation, detect internal faults, and cancel outputs if either hand control is released.
