Voltage and current sensors
30A Current probe 1W-UNI: 0–30A sensor for indirect AC current measurements
30A Current probe 1W-UNI is a 1-Wire sensor for indirect (without cutting the wire), single-phase measurement of AC current up to 30A. The split-core current transducer can be opened in order to insert a line wire. The sensor is suitable for monitoring power consumption of racks, BTS's or server rooms.
Sensor 0-20mA 1W-UNI
Electrically isolated current sensor for the 1Wire-UNI bus. Sensor for measuring currents in the 0–20mA or 4–20mA range. It is typically used to connect a remote industrial probe (e.g. to measure the fuel level in a tank).
Sensor 0-15V 1W-UNI
Electrically isolated sensor for measuring voltages from 0 to 15VDC. Typical applications include connecting external sensors (0–10V) to a monitoring system or monitoring the voltage of 12V batteries.
Sensor 0- 60V 1W-UNI
Electrically isolated sensor for measuring voltages from 0 to 60 VDC. Typically used to monitor battery voltage in telco applications (-48V standard).
PowerEgg
110 to 230VAC mains voltage detector and controller with electrical isolation. Inputs and outputs are low-voltage contacts.
- Power DETECTOR (relay contact if power connected)
- Power CONTROL (Switch on/off power by low voltage relay contact)
Sens-UI
Converts electrically isolated analog voltage (0 to 15V) and current (0 to 25 mA) signals at two inputs to a RS-485 line. Fits on a DIN rail.
- Interface: RS-485 bus (Poseidon 2250), up to 1000m, terminal block
- Construction: Converter to mount on a DIN rail
Sens-1W-UDI86 Multifunction Sensor
Analog and digital inputs for the 1-Wire UNI bus. Sens-1W-UDI86 features six dry contact digital inputs and eight 0-15V analog inputs. Electrically isolated, requires a 12VDC power supply.
