Function Description
The two-hand relay is a safety device to ensure that operators keep their hands away from the danger zone. The relay is suitable for use with mechanical and hydraulic presses, or in safety circuits. A cycle can only be initiated by
pressing the two pushbuttons simultaneously (within 0.5 s). A cycle is interrupted by releasing one or both buttons to stop the output. The output signal can only be reinitiated after both inputs have been released and the pushbuttons are operated again.
