1. Overview
The Y401-0011-L is a single-channel point-to-point wireless analog I/O terminal based on LoRa modulation. A standard system uses two factory-paired modules, Device A and Device B. Each module provides one 4-20 mA analog input and one 4-20 mA analog output.
Each analog input at one device is transmitted over the wireless link and reproduced as the corresponding 4-20 mA analog output at the other device. The same signal paths can operate in the reverse direction. The wireless link is half-duplex.
Signal Mapping
| Direction | Signal path |
|---|---|
| Device A to Device B | Device A AI1 -> wireless link -> Device B AO1 |
| Device B to Device A | Device B AI1 -> wireless link -> Device A AO1 |
2. Ordering Information
Model Configuration
Y401-0011-L is a one-to-one LoRa analog pair with no digital I/O. Each device provides one AI channel and one AO channel.
For the full code and examples, see Model Naming.
Channel Configuration
| Digital input | Digital output | Analog input | Analog output |
|---|---|---|---|
| 0 | 0 | 1 | 1 |
System Configuration
A standard Y401-0011-L wireless link uses two factory-paired modules: Device A and Device B. No on-site configuration is required for normal operation after the modules are connected to power and wired to the field circuits.
3. Key Features
- Bidirectional point-to-point transfer between factory-paired modules
- Active current input and output interfaces
- Reverse-polarity protection and hardware watchdog

5. Interfaces and Indicators
Terminal Layout
Viewed from the front, terminal positions run from left to right. The row positions below identify physical locations, not printed terminal numbers.
| Row Position | Upper Row | Lower Row |
|---|---|---|
| 1 | Power −: DC supply negative | AI+: analog input positive |
| 2 | Power +: DC supply positive | GND: input return |
| 3 | Unused; leave unconnected | Unused; leave unconnected |
| 4 | Unused; leave unconnected | AO+: analog output positive |
| 5 | Unused; leave unconnected | GND: output return |
Connect the 9 to 36V DC supply to the upper-row + and − terminals. AI+/GND accepts the 4-20 mA input signal; AO+/GND provides the active 4-20 mA output. The SMA antenna connector sits above the lower terminal row. Use the actual terminal markings when wiring.
The wiring diagrams mark the negative sides of the analog input and output as ground. Do not assume galvanic isolation between the power, input, and output circuits without a confirmed electrical diagram.
LED Indicators
| LED | Function | Status |
|---|---|---|
| Work | System operating status | On after the system starts |
| Link | Wireless link status | On when the paired device is connected; flashing indicates abnormal communication; off when disconnected |
| Input | Analog input status | On when an input current signal is detected |
| Output | Analog output status | On when the module is producing an output current |
6. Mechanical and Environmental
Mechanical Specifications
| Parameter | Specification |
|---|---|
| Dimensions | 58.7 × 111.2 × 36.5 mm |
| Weight | Approx. 350 g |
| Mounting | 35 mm DIN rail |
Environmental Specifications
| Parameter | Specification |
|---|---|
| Operating temperature | -20 to +75 °C |
| Operating humidity | 10% to 90% RH, non-condensing |
7. Installation and Wiring
See the user manual for two-, three-, and four-wire transmitter connections, two-wire AO connections, and commissioning.
Use active 4–20 mA input signals and compatible passive current receivers. Power two-wire transmitters from an external loop supply; module power connects separately from AI/AO signals.
8. Important Notes
- The half-duplex wireless link has variable delay and is unsuitable for guaranteed timing or as the sole emergency-stop/personnel-safety path.
- Input acquisition accuracy and output error are separate product limits. Include instrument errors when assessing the complete measurement path.
- Output loading depends on supply headroom as well as resistance. At 20 mA, a 500 ohm load alone needs 10 V; the 9 V minimum supply does not establish operation at maximum load.
- Validate output behavior during link loss and recovery before connecting a control load. Provide independent protection for the controlled process.
