== | == Inputs== | ||
Model WB-MRPS6 '''is not equipped''' with discrete inputs. | |||
== | == Installation of modules == | ||
The relay module is mounted on a standard 35 mm wide DIN rail and occupies the width of 3 DIN modules. | |||
Terminal blocks with 3.5 mm increments on the relay board are used to connect power and control lines (RS-485). The cross-section of wires connected to the screw terminals of the relay outputs must correspond to the power of the switched load: it is important not to exceed the recommended current — 16 A. | |||
If the device is the last one on the RS-485 line, a 120 Ohm resistor-terminator must be installed between its inputs A and B. Practice shows that in case of bench tests with a small length of the RS-485 line and a small number of devices, terminator for the last device in the line is not necessary. | |||
The module must be installed in such a way as to meet the requirements of electrical safety and to prevent accidental contact of contacts under high voltage. The module must be operated under recommended environmental conditions. | |||

== | == Relay operation in case of power failure == | ||
Depending on the value written to the storage register 0x06, after the power is turned off and restored, the relays will remain off (if the value is 0, or turn on those that were turned on before the power interruption if the register has a value of 1). This feature appeared in the modules with the firmware, starting with version 1.5.3. | |||
== | ==Modbus Control== | ||
Details of the work with the module via Modbus Protocol is written in [[Relay Module Modbus Management/en| Relay Modules Modbus Management ]]. | |||
There you can also find a map of the device registers. | |||

== | == Device firmware update == | ||
Starting with the new firmware versions of the device, the firmware update functionality (firmware) via the Modbus Protocol is supported. This makes it possible to extend the functionality of the devices and eliminate errors in the firmware directly at the installation site. Read more about flashing devices described in the article [[WB-MCU-Flasher|Download firmware to Wiren Board devices]]. A list of firmware versions that support the update, as well as devices for which this feature is implemented, can be found in [[Firmware_Changelog/en| Firmware Changelog]]. | |||
