Switch Box 2 – Industrial remote switch and control unit
Main features
Control of AC and DC outputs
Output overcurrent monitoring
Industrial communication interfaces
Ethernet, RS485, and RS232 ports provide flexible wired data transmission and network connectivity.
MODBUS RTU over TCP/IP support
A standard industrial protocol for easy integration into existing SCADA, PLC, or building management systems.
External sensor interface (I²C)
Direct reception of digital environmental sensors, such as SHT21 temperature and humidity sensors.
Versatile analog input
NTC thermistor, or reception of standard 4–20 mA or 0–10 V signals from industrial transmitters.
Contact status monitoring
Two digital inputs for monitoring the status of external switches, limit switches, or alarm contacts
