• 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 instantaneous output to 0.
• Start signal control for the H3DK-M.
