Power supply:
- 24 VAC (±15%), 50 / 60 Hz (±3 Hz), 3 VA max not isolated
- 24 VDC (-15%, +65%), 2 W max not isolated
supplied by a class 2 circuit.
Protect the power supply by one of the following fuses:
- 160 mA-T if the device is powered in alternating current
- 80 mA-T if the device is powered in direct current.
If the device is powered in direct current, it will be necessary to respect the polarity of the
power supply voltage.
The power supply must galvanically be isolated by those of the other elements of the RS-485
network with MODBUS communication protocol or the CAN network with CANBUS
communication protocol.
Rated impulse voltage: 4 KV.
Overvoltage category: III.
Software class: A.
Real time clock:
incorporated (SuperCap).
Data maintenance in case of absence of the power supply: 24 h with battery full loaded.
Battery loading time: 2 min (the battery is loaded by the power supply of the device).
Type 1 or type 2 actions: Type 1.
Features of actions type 1 or
type 2:
C.
Display: 320 x 240 pixel color resistive touch-screen TFT graphic display.
Communication ports:
3 ports:
- 1 RS-485 port with MODBUS communication protocol
- 1 CAN port with CANBUS communication protocol
- 1 USB port.
