== | == Installation of WB-MR3xV and WB-MR6xV modules == | ||
The relay module is mounted on a standard 35 mm wide DIN rail and occupies a width of 3/6 DIN modules. | |||
The screwless terminal blocks on the relay Board are used to connect power lines, control (RS-485) and input contacts. When used with the mounting lugs of the type NSVI to install wires into screwless terminals it is necessary that the diameter of the insulated cuff does not exceed 3.6 mm, wire size — 0.75 mm<sup>2</sup>, and the length of the conductive sleeve — 5-6 mm. Screw terminals accept wire cross-section 2,5—4 mm<sup>2</sup>. The cross section of the wire must correspond to the switched load. | |||
It is important not to exceed the recommended current of 16 A, when connecting switched devices to the KX relay contacts. | |||
The current flowing when a button or switch is shorted is small, so the type of button or switch can be anything. Despite the built-in anti-rattle protection, choose quality buttons and switches to avoid false positives due to bad contacts. Caution-in the HV modification, high voltage is present at the terminals! | |||
If the device is the last on the RS-485 line, a 120 Ohm terminator resistor must be installed between its inputs A and B. Practice shows that in the case of bench tests with a small length of the RS-485 line and a small number of devices, the terminator on the last device in the line can not be installed. | |||
The module must be installed in such a way as to meet electrical safety requirements and prevent accidental contact of contacts under high voltage. The module must be operated under recommended environmental conditions. | |||

== | == Relay operation mode 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 ]]. | |||
You can also find a map of the device registers there. | |||
