PURPOSE:To provide means for easy supply of check input signals by installing switches on a frame to apply contactors and check input signals to the applicable input terminals of a sequencer digital control unit. CONSTITUTION:A sequencer panel 2 is provided on its terminal board 1 with a plurality of input terminals 3, 3...... AC voltage supplied by on-off switches is input into input terminals 3, 3......, with these input signals being transmitted to a control unit in the sequencer. A plurality of switches 5, 5.... are secured on the surface of a frame 4, and contactors 7, 7.... corresponding to terminals 3, 3.... are installed beneath two holders 6, 6 installed below the frame 4, having insulation in the longitudinal direction and electrically connected to corresponding switch 5, with check input being applied to the terminal 3 upon turning on and off the respective switches. |
