Expansion unit
■ Input relay time constant
By setting special utility relays 2609 to 2612 to ON, the time constant in input expan-
sion units can be set to 10 µs.

Output Relays
Output relays output the program execution results to the outside. There are two
types of outputs, relay and transistor.
Note 1: Output relays function as contacts and relay coils in programs.
Note 2: There is no restriction of the contact type (N.O. or N.C.) used, the order the
relay Nos. are used, or the number of relays used.
Output operation time
•
Transistor output
OFF
➞ ON: 50 µs or less (10 µs or less in 500 to 502)
ON
➞ OFF: 250 µs or less (10 µs or less in 500 to 502, 100 µs or less for other
outputs in the basic unit)
•
Relay output
OFF
➞ ON: 10 ms or less
ON
➞ OFF: 10 ms or less
Note 1: When programming direct clock pulses, output relays 0500 and 0501 are
used to output pulses in a transistor-type output unit.
Note 2: When the ramp-up/down control function is used, output relay 0502 outputs
positioning pulses in a transistor-type output unit.
➮ "Chapter 5. Positioning Control" (p.3-253)
Note 3: When the specified frequency pulse output function is used, output relay
0501 outputs pulses in a transistor-type output unit.
