Product Description
Y402-44-L is a four-channel one-to-many LoRa I/O system. One master can communicate with multiple slave units, and each of the four channels operates independently for distributed field control.
Key Specifications
| Topology / product type | One-to-many, bidirectional |
|---|---|
| Channels / ports | 4DI + 4DO per master/slave |
| I/O / link mapping | Master DI1–DI4 to matching channels on all slaves; slave channels report to master; bidirectional |
| Node / variant configuration | 1 master + 1–6 slaves (current product options) |
| Frequency band | 398–525 MHz |
| Communication range | Up to 5 km (open area; model, antenna, and site dependent) |
| Power input | 9–36 VDC |
| Max power consumption | Master: 2 W max.; slave: 1.5 W max. |
| Input signal | 4 × passive dry-contact / NPN open-collector inputs per master/slave; no voltage input to DI |
| Relay output | 4 × SPDT relays per master/slave; AC 277 V / 5 A or DC 28 V / 5 A |
| Dimensions | 88 × 72 × 59 mm (master and slave) |
| Mounting | 35 mm DIN rail |
| Operating environment | −20 to +85 °C; 10% to 90% RH, non-condensing |
| Protection rating | IP20 |
Best Fit
- One control point linked to several remote cabinets.
- Four-channel pump, valve, lighting, and equipment control.
- Sites that need bidirectional master/slave signaling without wiring between points.
Operating Logic
- Master DI1 to DI4 drive the corresponding DO channels on all slaves.
- Any slave DI channel can drive the matching DO channel on the master.
- The master output resets only after the same channel on all slaves returns to open.
Before Ordering
This model is for four independent channels across one-to-many topology. If one signal should drive four outputs together, compare it with Y402-4411-L.
