• When connecting directly to this module’s input circuit, be sure
to use a PNP output sensor.
You cannot connect directly via a 2-wire sensor or an NPN-type
sensor. For details about NPN-type sensor connections,

(1) 1A Fuse (Fast-break type)
• Do not use negative voltages for the analog inputs. Doing so can
damage the internal circuit.
• The maximum length of the cable connected to an analog device
is 10 m.
