Analog input module WB-MAI2-mini/CC Buy online


Purpose

WB-MAI2-mini/CC is a compact analog input module designed to measure current signal 4..20 mA via two independent channels. The module is controlled from the controller or PC via RS-485 bus by Modbus commands.

Specifications

Table 1. Technical parameters.
Parameter Value
Power
Supply voltage 9 V – 28 V
measurement Channels
Number of channels 2
Current measurement 0 – 20 mA
Input impedance A 49.9 Ohm
Current measurement error ±1%
Control
Management interface RS-485
Interface isolation no
Communication protocol Modbus RTU, the address is set by software, factory settings are indicated on the label
RS-485 interface parameters Default speed of 9600 bps; data bits 8; parity N; stop bits 2.

Interface parameters can be configured programmatically:

Ready for operation after power supply 1 c
dimensions
Size 57 x 18 x 14 mm
operating Conditions
Air temperature
Relative humidity up to 98%, without condensation

Connection diagrams

The module is made in a compact housing and is designed for installation in solder boxes and cable channels.

Сurrent measurement

The figure shows the connection diagram of sensors with a current output of 0-20 mA (4-20 mA). The internal resistance of the inputs — 49.9 Ohms.

Presentation in the web interface

WB-MAI2-web.png

The web interface for the module displays current values (controls "Current input 1 (mA)" and "Current input 2 (mA)"), supply voltage and serial number. The "CC" in the device name indicates that it supports two current inputs (Current).

Description of Modbus registers

All Modbus registers of the device are divided into 2 groups:

  • General registers that define device parameters
  • Registers of measured values

General registers

Register/ address type read-write default format purpose
104-105 input R 32-bit unsigned int uptime counter in seconds
110 holding RW 96 baud rate / 100 RS-485 port speed, divided by 100. Permissible speeds: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
(configure RS-485 communication parameters for Wiren Board Modbus devices)
111 holding RW 0 configure the RS-485 port parity bit. Valid values: 0 - no parity bit (none), 1 - odd (odd), 2 - even (even)
112 holding RW 2 number of stop bits of RS-485 port. Valid values: 1, 2
120 (0x78) holding RW 0 0 write to the register causes a stateless 
reboot of the module
121 (0x79) input R - mV current supply voltage of the module
128 (0x80) holding RW written on the label on the case Modbus address of the device
200-206 input R | | device signature
