AT-FM-2A

The AT-FM-2A is a DUO-TOUCH® two-hand Control Safety Module with SPST-NO contact configuration. A DUO-TOUCH® two-hand control safety module for use with two banner OTB optical touch buttons (each with one normally open relay output contact, one with current-sourcing PNP output and one with current-sinking NPN output) or two mechanical push buttons, each with one normally open contact. If the machine operator removes one or both hands from the actuating devices, the DUO-TOUCH® module relays de-energize, causing the output contacts to open. The relays will not re-energize until both actuating devices are deactivated and then simultaneously reactivated (SSI input channels closed). The DUO-TOUCH® two-hand control safety module may be used as an initiation device for most powered machinery when machine cycling is controlled by a machine operator.

• Feedback input for monitoring external machine control elements
• Four indicator LEDs for power, input 1, input 2 and fault
• Protected against transient voltages & reverse polarity (DC hookup is without regard to polarity)
• NEMA 1 (IEC IP20) rated polycarbonate housing
• 500ms (maximum) Simultaneity requirement for touch-/push-button operation
• 25ms Maximum output response time
