MTREL-100
The relay module MTREL-100 is a switching module for heavy loads from myTEM
for extending your smart home system with additional 16 A outputs. For this,
the device is connected to your central myTEM Smart Server via the CAN bus
system.
The programmable behavior allows flexible use of the device in the house.
SAFETY INSTRUCTIONS
-
Operate this device only as described in the manual.
-
Do not operate this device if it has obvious damage.
-
This device shall not be altered, modified, or opened.
-
This device is intended for use in buildings in a dry, dust-free location.
-
This device is intended for installation in a control cabinet. After installation, it must not be openly accessible.
-
Electrical equipment may only be installed and fitted by qualified electricians who are familiar with and comply with the applicable regulations and standards.
-
CAN bus and device supply must comply with the ELV requirements. Do not connect ELV and mains voltage together. (ELV = extra-low voltage)
-
If several motors are to be connected in parallel at one output, be sure to observe the manufacturer’s instructions and, if necessary, use isolating relays.
Otherwise, the device may be damaged. -
Only use blind motors with mechanical or electronic limit switches. Limit switches must be checked for correct adjustment. Otherwise, the device may be damaged.
-
Do not connect three-phase motors, the device may be damaged.
Applications:
- Switching of high current devices
- Switching of power outlet sockets
- Switching of lights
- Switching of single-phase fan motors
- Switching of electric blinds or similar shading devices
- Operation by means of buttons, sensors via the central server
Functions:
- Supply voltage 24 VDC ± 10% with support terminals for further wiring
- CAN bus
- 12 digital outputs with potential-free relays 16 A, 250 VAC or 30 VDC (DO1 – DO12)
- Manual positions of the outputs via DIP switch for easy commissioning
- The device is installed in a control cabinet, mounted on a 35 mm DIN rail
WARNING! The maximum current across all relays must not exceed 48A
Installation
WARNING! Depending on national safety standards, only authorized and/or
trained technicians may be allowed to perform electrical installations on the
power grid. Please inform yourself about the legal situation before
installation.
Please install the device according to the following steps:
- WARNING! Make sure that the device is disconnected from the power supply or that the devices in the control cabinet are disconnected from the mains.
- WARNING! Connect the device according to the circuit diagram of the myTEM ProgTool or the terminal assignment from the picture above. Incorrect wiring can result in injury or death or damage to the device.
- CAUTION! The device shall only be operated with stabilized power supplies (24 VDC). Connecting to higher voltages will damage the device.
- The last device on the CAN bus requires the terminating resistor of 120 Q enclosed with the myTEM Smart Server via terminals (CAN +/—).
- WARNING! Switch on the power supply and, if necessary, check the wiring with the manual positions via the DIP switch. Take care of your safety as the de vices are live.
Behavior after power failure
After a power failure, all outputs are switched off until the new settings are received from the myTEM Smart Server or myTEM Radio Server.
Quick troubleshooting
The following hints may help solve trouble:
- Make sure that the power supply is connected with the correct polarity. With wrong polarity, the device does not start.
- If a device cannot establish communication to the myTEM Smart Server or myTEM Radio Server, check if the CAN bus (+/—) is correctly wired and the ground (GND) is connected. A missing ground connection (usually available via power supply) can affect the communication.
- If a device cannot establish communication to the myTEM Smart Server or myTEM Radio Server, check whether the terminating resistor of 120 0 at the last device is connected to the CAN bus. If missing, please add it via terminals (CAN +/—).

Manual positions via DIP switch
With the aid of the DIP switch, the outputs (e xception output DO12 ) can be checked after installation.
- CAUTION! While manual settings are used, the control commands from the myTEM Smart Server or myTEM Radio Server are ignored.
- CAUTION! Before starting, set all DIP switches to position OFF, i.e. upwards. This avoids that e.g. OPEN / CLOSE commands are set at the same time.
- To check the digital outputs (relays) set DIP switch 12 down to ON.
With the DIP switches 1 – 11 you can now switch the relays DO1 – DO11 on and off.
LED display
The LED next to the CAN connector may show the following states:
LED green: Device started and connection to the myTEM Smart Server or
myTEM Radio Server working
LED flashing green: The device is in the manual position
LED red: Device started but no connection with the myTEM Smart Server or
myTEM Radio Server
LED off: Device not powered, not started, or broken
