T-R Resistance Transducer

T-R Resistance Transducer

The T-R resistance transducer converts a variable resistance into a load independent dc current or voltage signal.
There is galvanic isolation between the input, output and the auxiliary supply circuits.

Basic Specifications:
InputDC voltage from current injection (2 wire method)
(3 wire method available on request but without galvanic isolation between input and output)
Excitation current: 5mA - 20mA dc
Resistance 0-Rnom: 0-20Ω to 0-2kΩ
Accurate range: 0 - 100% Rnom
OutputLoad independent dc current or voltage
Standard outputs: 0 - 10mA dc <1500Ω load
(others on request): 0 - 20mA dc <750Ω load
: 4 - 20mA dc <750Ω load
: 0 - 5V dc >2kΩ load
: 0 - 10V dc >2kΩ load
Accuracy: Class 1 to IEC 60688
Power Supply: 24V, 110V, 230/240V, 400/415V ac ±20%, 2VA
: 24V dc ±20% or 110V/125V dc (88V-138V), 2W
IsolationGalvanic isolation between input, output circuit and auxiliary supply
Test voltage: 4kV 50Hz ac for 1 minute
TemperatureOperating: -10°C to +20°C to +50°C
EMC Approvals: AS/NZS 3548
C-Tick Mark: C-Tick Mark approved
