Wireless 2 digital outputs module (SSR) - MIDAM WOUT251
A small wireless module with two digital outputs (SSR) designed for two-state or PWM switching of suitable end devices. It also has an integrated modbus map that guarantees seamless integration into the parent system. Communication is via the AES128 encrypted Midam KFP protocol, which enables wireless firmware updates in the device.
- Module with 2 digital SSR outputs
- Integrated Modbus map
Function
The module features two outputs (Solid State Relay) and thanks to its compact dimensions it is suitable for flush mounted installation. SSRs work according to „zero cross turn on“ function. Output 2 can be controlled by a PWM signal with adjustable period. Wireless communication is based on an unlicensed 868 MHz band. Embedded AES 128-bit, provides the most secure encryption standard for wireless connections. Signals are received from a transmitter, for example, WINXxx, WKEY401, or WRU01001 (WRU90001) room controller for direct control according to the desired value (setpoint with hysteresis). The device has factory-set values to ensure the correct default function and allows direct reading and writing of values to the Modbus map, which is available in a separate document. All settings are also stored in the Modbus map directly in the device. Before using the device for the first time, it is necessary to pair it and it is recommended to perform individual configuration, especially to change the encryption password.
Aplikace
- Wireless module with two digital outputs (SSR)
- Control of lighting or shutters/blinds
- Control of motors, solenoids, and heating elements
- Wireless integration into a higher-level control system
- Wireless PWM output control (output 2)
- General-purpose use
Pairing
Two devices are required for mutual communication. Both must be powered and located in close proximity to each other. Usually, wireless gateway or configuration dongle is used to set up remote wireless devices. Use look-up function in software tool to display a list of all available devices in range and assign or adjust parameters based on wireless ID code for each single device. There is a comprehensive help section integrated in the software tool.
SCADA system integration
WCOM01, resp. WCOM51 wireless gateways are recommended for direct integration into SCADA systems.
Midam KFP Password change
Prior to the first use, the encryption password (default “MIKROKLIMA1234AB”) must be changed using the WUSB01 configuration dongle and the relevant software tool.
