MODEL CUB7T1 PROGRAMMABLE GENERAL PURPOSE ELECTRONIC TIMER
DESCRIPTION
inch (8.90 mm) high digits. It has an LCD read-out available in Positive Image
Reflective (CUB7T100), Negative Image Transmissive with yellow/green
backlighting (CUB7T110) or red backlighting (CUB7T120). The backlight
versions require an external 9 to 28 VDC power supply. The display will wrap
around from a full display of “99999999” to “00000000” when an overflow
occurs. An annunciator, located in the upper left hand corner of the display,
blinks at 2 Hz when the signal input is activated. The Voltage versions
(CUB7T1xxx) operate from a signal voltage of 10 to 300 V (AC 50/60 Hz or
DC).

buttons meets NEMA 4X/IP65 specifications for wash-down and/or dusty
environments, when properly installed.
SAFETY SUMMARY
bulletin or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
