99.99 s, 999.9 s, 99 min 59 s, and 99 hrs 59 min.
Selection of elapsed time indication, remaining time indication,
contact output, and transistor output types to suit requirements H7ER-NV-BH.
Power supply freely selectable within a range of 100 to,
240 VAC, as well as 12 to 48 VDC.
Certified for UL and CSA safety standards. Supply voltage: 24 to 240 VAC/DC.
Control output: Contact output, DPDT (time-limit DPDT,
or time-limit SPDT + instantaneous SPDT)Changed using a switch H7ER-NV-BH.
Eight-mode Timer.
Multiple time ranges and operating modes let you cover a wide,
range of applications.
The time-limit DPDT output contacts can be changed to time-limit,
SPDT and instantaneous SPDT output contacts using a switch.
Sequence checks are easily performed by setting an instanta,
neous output to 0.
