1. Overview ​

The Y401-0044-L is a four-channel point-to-point wireless analog I/O synchronization module using LoRa communication. Each module provides four analog inputs and four analog outputs. Order the module with either a 4-20 mA current signal configuration or a 0-10 V voltage signal configuration.

A link uses two modules. Analog inputs at one module are transmitted wirelessly to the corresponding outputs at the other module. On the 4-20 mA version, the four channels operate independently over a half-duplex link. The pair is matched at the factory and needs no on-site configuration for normal operation. The signal configuration, accuracy, and loading limits must match the ordered version.

Signal Mapping ​

ChannelDevice A to Device BDevice B to Device A
1AI1 → AO1AI1 → AO1
2AI2 → AO2AI2 → AO2
3AI3 → AO3AI3 → AO3
4AI4 → AO4AI4 → AO4

Use matching signal types at the source, module input, remote output, and receiving instrument. Select one signal configuration for the module pair and use matching field instruments.

2. Ordering Information ​

Model Configuration ​

Y401-0044-L is a one-to-one LoRa analog pair. The first two digits, 00, indicate no digital I/O on either side; the final two digits, 44, indicate 4 AI and 4 AO on each device.

For the full code and examples, see Model Naming.

Signal Options ​

Signal typeNominal range
Current4-20 mA
Voltage0-10 V

Specify the required signal type when ordering. The faceplate has separate marks for the two ranges. Use the supplied signal configuration and do not connect a different signal type.

3. Key Features ​

  • Four matching analog signal paths in each direction
  • Current or voltage configuration selected when ordering
  • Active constant-current outputs on the 4–20 mA version
  • Individual channel indicators and labeled output/return terminal pairs

Terminal Layout ​

The following order follows the faceplate viewed from the front, left to right. The positions below identify locations in each row, not printed terminal numbers.

Row positionUpper rowLower row
1−: DC supply negativeAO1+: channel 1 output
2+: DC supply positiveGND: output return
3AI1+: channel 1 inputAO2+: channel 2 output
4AI2+: channel 2 inputGND: output return
5AI3+: channel 3 inputAO3+: channel 3 output
6AI4+: channel 4 inputGND: output return
7GND: input returnAO4+: channel 4 output
8GND: input returnGND: output return

Connect each output circuit to its labeled AO terminal and adjacent GND. The GND markings do not establish galvanic isolation between channels or between signal and power circuits.

Indicators ​

The following status descriptions apply to the 4-20 mA version.

7. Installation and Wiring ​

Use the user manual for 4–20 mA input wiring, two-wire AO connections, 0–10 V wiring, and commissioning.

The four inputs share the input GND terminals. Each output uses its labeled AO+ and adjacent GND. Module and field-instrument power connections are separate from the signal pairs.

8. Important Notes ​

  • Range figures assume an open-area installation. The 10 km option requires the specified configuration and antenna; obstructions, interference, and antenna placement affect the installed link.
  • Use the ordered current or voltage configuration throughout the signal path. Do not apply a voltage signal to a current-configured input.
  • Current-version load limits do not define voltage-output drive limits. Check the voltage output's minimum load resistance against the receiver input impedance before connection.
  • The 4–20 mA version uses half-duplex communication with variable delay. Assess timing and output behavior during link loss and recovery before connecting a control load.
  • Do not use the wireless link as the sole emergency-stop or personnel-safety path.
