OSC-16 for imc CRONOS-PL/-SL/compact
16-channel isolated differential amplifier
Data Sheet version 3.4
The OSC-16 is a scanner module with optical relays, equipped with 16 isolated and differential input
channels. It comes with enhanced isolation strength of up to 60 V, and its 16 channels allow
measurement of voltage, current, thermocouples and Pt100. The OSC-16 is available as a plug-in module
for imc CRONOS-PL/compact and as a configuration module for CRONOS-SL.
Highlights
Ideal for isolated measurement of passive sensors
optimal suppression of 50 Hz interference
support of TEDS (imc Plug & Measure, Transducer Electronic Data Sheets (IEEE 1451.4)
imc CRONOScompact - modular measurement system
imc CRONOScompact is a modular and reconfigurable hardware a
"rack"-based series of devices available in different housing sizes
and device frames.
imc CRONOScompact (CRC) plug-in-modules can be plugged in
imc CRONOScompact System (CRC-400 / CRC-2000G). This
assembly of such a system can be adapted fast and easily.
imc CRONOScompact plug-in-modules
Once the modules are built-in a portable or rack-based housing,
the modules will electrically connected to the imc
CRONOScompact (CRC) system and they will also be supplied by
the system. The data storage will also be managed by CRC.
The front panel of the rack-based modules ("-R") is different to the
front panel of the portable housing. The properties of both types is
the same.
