Q408 Multi-Channel Isolator
Brand: EurothermThe model Q408 is a DC powered, DIN rail mount, DC input signal conditioner, with 1,800 V isolation between input, output and power.
The field configurable inputs and outputs provide flexible, wide ranging capability for DC current and voltage signals.
The Q408 is available as a single channel signal conditioner (1 input / 1 output) or a multi-channel signal conditioner (2 inputs / 2 outputs).
All models maintain the high 1,800 V isolation level from channel to channel, as well as input to output to power.
