Minimum pulse width 80µs
Environmental
IP20
Operating temperature
0° to 50° C
Storage temperature
-20° to 60° C
Relative Humidity (RH) 5% to 95% (non-condensing)
Dimensions (WxHxD) 80mm x 93mm x 60mm

Notes:
1. Input #15 can function either as a high-speed counter, a frequency measurer, or as a normal digital
input. When Input #15 is used as a normal digital input, normal input specifications apply.
2. Input #14 can function either as the counter’s reset, or as a normal digital input; in either case, its
specifications are those of a normal digital input.
