Safety relay / for two-hand controls - 24 - 230 V | DUO-TOUCH SG series
These two-hand control safety modules create an ergonomic, complete system by working with Banner STB touch buttons that self-check or by being retrofitted with palm buttons that are mechanical. The modules feature several redundant output contacts that are force-guided and a diverse-redundant microcontroller circuit. Both touch buttons must be activated within a half second of one another as required by the anti-tiedown logic. Available voltages include 24VAC/DC, 115VAC/24VDC or 230VAC/24VDC. Some modules have non-safety auxiliary outputs available, and all modules have two or four normally-open safety outputs. The Safety Category 4 in the ISO standard 13849-1 (EN 954-1) is met, and as per EN 574, the units meet the functional Type IIIC two-hand control. Wiring and module exchanges can occur without rewiring due to removable terminal blocks, and during the machine cycle's non-hazardous portion, actuating buttons can be released due to optional mute inputs. Kits include two STB touch buttons and a module.
