Transducers
Isolators [Insulated]
Isolators provide insulation between DC circuits and measurement equipment,
and between various sensors and control equipment.
Isolators can be used as a buffer or level exchange between input/output.
Applications
Insulation between DC circuits and measurement equipment
 Insulation interface between each sensor and other equipment such as computers or data loggers
Insulation between separate circuits

Resistance between input terminals
Combine with a shunt if the current input exceeds 0.1A.
Isolators that provide positive/negative bidirectional output or positive direction-only output for
positive/negative bidirectional input can also be manufactured.
The manufacturable ranges for a bidirectional output are ±50mV~±10V and ±0.1~±5mA.
Please inquire separately regarding input specifications exceeding 300V.
