The model is discontinued. Recommended replacement - WB-MCM8. Buy WB-MCM8 in the online store
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.
Terminals and wire section | |
---|---|
Recommended wire cross-section with TSVI, mm2 | 0,75 — 1 |
Length of the standard sleeve NSVE, mm | 8 (10 for adjusting screwless terminal blocks) |
Torque of screws, N∙m | 0,2 (for screw terminals) |
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.
