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

Note: Output duration is variable from 0-9990 ms. (Default: 100 ms)

When alarm settings are 0, the DC

output is the same as the output

operations for a relay output.

Note: Alarm settings should be less than preset values. Using

alarm settings with values that exceed preset values will result

in measurement values of 0 and the alarm output (DC output)

will come ON.
