Panasonic PM4HA-H-AC240V adds multi-mode flexibility to the PM4H platform. Eight front-selectable functions (Pulse ON-delay, Flicker, ON-flicker, Differential ON/OFF-delay (1)(2), Signal OFF-delay, One-shot, One-cycle) cover most machine and process sequences, while the sealed IP65 front tolerates wash-down and dust.
Features
- Eight timing modes with direct front selection
- 0.1 s–500 h span; ±0.3% fluctuation and ±5% setting error
- Dual change-over outputs (2 Form C) for interlocks/sequencing
- 11-pin screw terminal base for secure wiring
- Short 62.5 mm body; DIN48 cut-out compatibility
