Panasonic PM4H-M combines a timed relay with a parallel instantaneous relay for interlocks that need an immediate output plus a delayed action. Five modes cover typical control tasks, and the 0.1 s–500 h span handles both short and very long sequences.
Features
- Dual outputs: timed 1 Form C + instantaneous 1 Form C
- Five selectable modes (ON-delay, Power Flicker, ON-flicker, One-shot, One-cycle)
- Stable timing: ±0.3% fluctuation with ±5% setting error
- Short 62.5 mm body; 8-pin base; clear front dials
- IP50 front protection for control cabinets
