DIN48 SIZE

ANALOG MULTI-RANGE

CYCLIC TWIN TIMERS

PM4H-W

Features

• A single twin timer unit that repeats (variable) ON/OFF.

• Multiple ranges with a 0.1 s to 500 h time specification on a single unit.

• The output ON/OFF operation is indicated by red and green LED’s.

It’s easy to check the operation at a glance.

• The AC free power supply and shorter body make it easier to use.

• A new screw terminal type has been added to the conventional pin type. Wiring

can be done easily with a screwdriver.

• Compliant with UL, CSA, CE and LLOYD.

Notes: 1) Unless otherwise specified, the measurement conditions at the maximum scale time standard are specified to be the rated operating voltage (within 5% rip-

ple factor for DC), 20°C 68°F ambient temperature, and 1s power off time.

2) For the 1s range, the tolerance for each specification becomes ±10ms.

3) As internal components may become worn when using continuous conduction, the product should be replaced periodically.

Analog Timers PM4H SERIES MODES AND TIME SETTING 1. Operation method 1) Operation mode setting [PM4H-A type] 8 operation modes are selectable with operation mode selector. Turn the operation mode selector with screw driver. Operation mode is shown up through the window above the mode selector. The marks are ON , FL , FO , OF1 , SF , OS , OF2 , OC . Turn the mode selector to the mark until you can check by clicking sound. Confirm the mode selector position if it is correct.
