Overview
Koyo digital timers offer flexible features
at a great price. A large, easy to read
display is offered in a small 1/16 DIN
size. The large, bright red LED display
has a 12mm character display height
which allows it to be seen easily from a
distance and at an angle. In addition, set
values use a green LED display to differ-
entiate from timing values. Basic func-
tion settings are made with digital
switches. Detailed settings are selected
with digital keys, so operation is easy.
Features
• Tamper-proof: key protection can be
set for individual keys to prevent a
malfunction or tampering.
• Battery-less memory retention:
EEPROM is used to retain values in
memory, so there is no need for battery
maintenance.
• Maintenance has been reduced via
removable terminals. After wiring, the
terminal cover provides a safe barrier
for worry-free use.
• Power source for a large-capacity
sensor: you can source the power for
the sensor from the built-in power
source which supplies 60mA at
24VDC.
• Wide operating AC voltage range of
85VAC-264VAC.
• Various types of time ranges: covers ten
types of time ranges with times of
0.001 second to 9999 hours
• Five types of operating modes: settings
of on-delay, off-delay, one-shot, accu-
mulation and flicker
• Display of elapsed time/remaining time
• IP65 protective structure: front cover
panel is made of a clear membrane, so
operation with wet or dirty hands can
be worry-free.
• Fully CE and UL compliant
