Wireless 2 digital outputs module (combined) - MIDAM WOUT261
Small wireless module featuring two digital outputs (relay and SSR - with PWM function) designed to switch appropriate end devices. Native modbus map grants seamless integration into the SCADA systems. The communication is based on the AES128 encrypted Midam KFP protocol, which allows to update the device firmware on a wireless basis.
- Two digital outputs (relay and SSR)
- Integrated Modbus map
Function
The module features two outputs (1x relay and 1x Solid State Relay) and thanks to its compact dimensions it is suitable for flush mounted installation. SSR works 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.
Application
- Wireless module with two digital outputs (relay + SSR)
- Control of lights or shutters/blinds
- Power control panels and remote switching
- Gas pump electronics and contactors
- Control of solenoids, motors, or heaters
- Wireless control of PWM functions on output 2
- Wireless integration into SCADA systems
- 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 to provide support during the wireless device set up procedure.
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.
