Preset Counter/Timer (48 24) H8GN CSM H8GN DS E 3 3 A DIN 48 24 Preset Counter. Compact, Yet Equipped with Communication. Only 48 24 83 mm (W H D) Switch between 4-digit preset counter and 4-digit timer opera- tion. While using the preset counter, it is possible to switch the dis- play to monitor the totalizing count value (8 digits). Built-in prescaling for counter operation. ON/OFF-duty adjustable flicker mode that can be used to per- For the most recent information on models that have been certified for safety standards, refer to your OMRON website. form cyclic control is available for timer operation. SV can be changed using front panel keys to any of four values preset in SV-banks. Water-proof structure to NEMA4X/IP66. Conforms to UL, CSA, and IEC safety standards as well as CE Marking.

Counting range 999 to 9,999 Input modes Increment, decrement, individual, quadrature inputs Output modes N, F, C, or K Timer Time ranges 0.000 to 9.999 s, 0.00 to 99.99 s, 0.0 to 999.9 s, 0 to 9999 s, 0 min 00 s to 99 min 59 s, 0.0 to 999.9 min, 0 h 00 min to 99 h 59 min, 0.0 h to 999.9 h, 0 h to 9999 h Timer modes Elapsed time (Up), remaining time (Down) Output modes A, B, D, E, F, or Z Inputs Input signals For Counter: CP1, CP2, and reset For Timer: Start, gate, and reset Input method No-voltage input (contact short-circuit and open input) Short-circuit (ON) impedance: 1 k max. (Approx. 2 mA runoff current at 0 ) Short-circuit (ON) residual voltage:2 VDC max. Open (OFF) impedance: 100 k min. Applied voltage: 30 VDC max. Start, reset, gate Minimum input signal width: 1 or 20 ms (selectable) Power reset Minimum power-opening time: 0.5 s Control output SPDT contact output: 3 A at 250 VAC/30 VDC, resistive load (cos = 1) Minimum applied load 10 mA at 5 VDC (failure level: P, reference value) Reset system External, manual, and power supply resets (for timer in A, B, D, E, or Z modes) Sensor waiting time 260 ms max. (Inputs cannot be received during sensor wait time if control outputs are turned OFF.) Note: The figures given for maximum counting speed are for incrementing or decrementing operation with a prescale value of 1. If prescaling is used and 5 kHz is set, the maximum counting speed will be reduced to about half. The maximum counting speed will also be reduced to about half when the up/down mode is selected. 2
