Frequently Asked Questions
Q: What voltage options are available for the ZN48 Digital Time Relay Counter?
A: The ZN48 supports multiple supply voltages including 12VAC/DC, 24VAC/DC, 36VAC, 110VAC, 220VAC, and 380VAC at 50/60Hz, making it compatible with a broad range of industrial and commercial control panel installations worldwide.
Q: Can the ZN48 be used as both a timer and a counter?
A: Yes. The ZN48 is a true multifunction device — it can operate as a time relay (single or double delay, accumulation), an event counter (reversible, up/down), a frequency meter, and a tachometer/rotation counter, all selectable via the onboard dial switch settings.
Q: What type of sensors are compatible with the ZN48 counter input?
A: The ZN48 accepts contact-type and NPN-type sensor inputs. Compatible proximity sensors include M8 (2mm sensing distance), M12 (4mm), M18 (8mm and 2m), and M30 (4m) NPN models.
Q: How is the ZN48 mounted and what are the panel cutout dimensions?
A: The ZN48 is designed for panel-mount installation. The overall unit dimensions are 48×48×91mm and requires a panel cutout of approximately 46×46mm for a secure, flush-mount fit in a standard DIN-compatible control enclosure.
