{{#vardefine:ProductFullName1| 16-channel pulse counting module WB-MCM16}} {{#vardefine:FileName1|WB-MCM16}} {{#vardefine:ProductName1|WB-MCM16}} 

==== Purpose ====

The module of discrete and counting inputs 16-channel WB-MCM16 is designed to connect signals of dry contact and open collector, 
connection of metering devices of water, electricity, gas, etc. with pulse outputs.

No pre-configuration of input modes is required. There is protection against overfilling of the pulse counter.

Version: housing on DIN-rail (width 3 units).  Supply voltage 12 – 24V

The module is controlled from the controller or PC via the RS-485 bus by MODBUS commands, as well as by external buttons.

==Technical specifications==

* 16 digital inputs with pulse counting support with built-in voltage sources
* Minimum pulse duration: 21ms, maximum pulse frequency: 25 Hz
* Group galvanic isolation of inputs from RS-485 interface, up to 1.5 kV.
* Supply voltage: 11 to 24 V.
* Power consumption: 0.3 W.
* Interface: RS485, Modbus RTU.
* Save counter values when power is off
* Led indication for power and data exchange 
* Install in the electrical panel on a DIN rail, housing width 3 DIN.

====Operating conditions====

* Air temperature from -40°C to +50°C;
* Relative humidity up to 92%,without moisture condensation.

==== Connection ====

The module is made in a plastic case and is designed for installation in a mounting box on a DIN rail.
The scheme of inputs is shown in the figure. The terminal is supplied ~ 4.5 V, when the earth current flows a small (1.5 mA), causing the operation of the input.

Address change is broadcast (slave_id 0) team record (WRITE_SINGLE_REGISTER) to holding register with address 128 (0x80).

The address 200 has a 6-byte signature. The signature is unique for each device model and allows you to identify the model.
To obtain the signatures necessary to fulfill READ_HOLDING_REGISTERS address 200 length 6.  
Writing to this area of memory is not supported and error 3 is returned when attempting to write to an invalid location.
