Controller - SmartRelay 3 system
Housing | |
Material | ABS plastic, UV-stable |
Colour | Same as RAL 9016 (traffic white) |
Standard protection rating | IP20 |
Wiring to device |
|
Power supply (only one power supply must be connected) | |
Screw terminals |
The max. current depends on the supply voltage and the activity of the controller. |
Pin connector |
The max. current depends on the supply voltage and the activity of the controller. |
Power over Ethernet (PoE) |
The PoE supply voltage is reduced to 13 VDC by a voltage transformer. If you apply a supply voltage higher than 13 VDC to the screw terminals or the round plug, the controller is not supplied with voltage via the PoE interface, but via the voltage supply input with the highest applied voltage. |
Outputs | 3 outputs to supply external reader (VOUT = VIN – 1 VDC)* |
Battery | |
Type | 1x lithium cell CR1220 (3 V, 40 mAh) Manufacturers: Duracell, GP Batteries (Gold Peak), Murata, Panasonic, Varta. Batteries coated with bitter substances are not suitable. |
Exchangeable | Yes |
Duration |
Battery status can be called up via LSM. Battery is not used as long as controller is connected to power supply. |
Real-time clock (RTC) | |
Accuracy | max. ± 20 ppm (≈ 10 minutes per year) |
Ambient conditions | |
Temperature range |
|
Humidity | Max. 90%, non-condensing |
Interfaces | |
TCP/IP |
|
USB |
|
RS485 | Serves as interface to external readers (SREL3.EXT.*) and other bus devices.

IMPORTANT
*) Undervoltage at the reader with PoE supply
When the controller is powered via PoE, a voltage converter reduces the PoE supply voltage to 13V. This voltage is available for supplying the connected readers and may not be sufficient for long cables or too small cross-sections to ensure trouble-free operation of the reader (see also Information on cabling). Take one of the following actions:
- Use an external power supply for the reader.
- Use an external power supply for the controller, whose voltage significantly exceeds 13 VDC to increase the internal supply voltage. This also increases the supply voltage for the reader and the voltage drop on the line no longer has any effect.
- Shorten the cable length.
- Increase the cable cross-section.
