 The SC448 and SCL448 Strain
Gauge and Bridge Isolators/Transmitters allow low cost
retransmission of any Strain Gauge or Bridge circuit. Featuring
two fixed and two variable excitation supplies, they can isolate
and retransmit to a wide variety of external devices with standard
process signals.
The SC448 operates on line power (85 to 265
V DC or AC, 50 to 400 Hz) so no extra power supply is needed.
The SCL448 operates on low power (9.6 to 28
V DC or AC, 50 to 400 Hz) for systems that work exclusively at
low voltages. Dimensional
