50 PM4H-W 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. 48 1.890 48 1.890 62.5 2.461 mm inch Specifications Item Type PM4H-W Rated operating voltage 100 to 240V AC, 48 to 125V DC, 12V DC, 24V AC/DC 50/60Hz common (AC operating type) 5A 250V AC (resistive load) Cyclic (OFF-start/Twin operation) Rated frequency Rated control capacity 1s to 500h 16 time ranges switchable (T1, T2 time setting individually) ..0.3% (power off time change at the range of 0.3s to 1h) ..5% (Full-scale value) ..0.5% (at the operating voltage changes between 85 to 110%) Max. 100m..

52 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 , , , , , , , . Turn the mode selector to the mark until you can check by clicking sound. Confirm the mode selector position if it is correct. If the position is not stable, the timer might mis-operate. 2) Time range setting [PM4H series common] 16 time ranges are selectable between 1s to 500h....

53 PRECAUTIONS IN USING THE PM4H SERIES 1. Input connections (PM4H-A type) 1) Be sure not to use terminal .. as the common terminal of the input signal as shown in Fig. A. Otherwise, the internal circuit of the timer may be damaged. Use terminal .. as the common terminal as shown in Fig. B. If the circuits is connected as in Fig. C, the internal circuits must be broken. Be sure to connect the circuit as in Fig. D. 2) When one input signal is simultaneously applied to more than one timer, be sure to avoid the wiring shown in Fig. E. Otherwise, the short-circuit current will flow and cause...

54 PRECAUTIONS IN USING THE PM4H SERIES 5. Superimposed surge of power supply (PM4H series common) For the superimposed surge of power supply, the standard waveform is taken as the standard value for surge-proof voltage. If external surge occurs exceeding the specified value, the internal circuit may break down. In this case, use a surge absorption element. The positive and negative voltages are applied each five times between the power pins. The typical surge absorption elements include a varistor, a capacitor, and a diode. If a surge absorption element is used, use an oscilloscope to see...
