●High speed DC input module (positive common type) QX40H QX70H

●High speed DC input module (negative common type) QX80H QX90H

Speed up control by catching the input signal variation at 0 ms*3.
Two devices with differing power systems can be connected to the same module using different 8 point common terminals.

*3: The actual response time is 5 µs delay when turning ON, 10 µs delay when turning OFF, because the hardware response time is added.

●Spring clamp terminal block type output module QY10-TS QY40P-TS QY80-TS

Spring clamp terminal blocks visually indicate the connection status. Also, by eliminating screws, wiring and maintenance work is made easier.

Advantages of spring clamp terminal blocks

Advantages of spring clamp terminal blocks

  • Impervious to vibration, secured wiring connections.
  • Eliminating screws greatly simplifies conventional maintenance.
