Technical datasheet
OSC-16 for imc CRONOS-PL/-SL/compact
16-channel isolated differential amplifier
Datasheet version 3.3 23.10.2012
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)

Physical structure:
Plug-in module for imc CRONOS-PL/compact systems, occupying two slots
Terminal connection:
4x DSUB-15 terminals (4 channels per connector)
16x thermocouple sockets (-T)
16x 7-pin LEMO terminals with 1 channel per connector plug (only with CRSL/OSC-16-L)
For this module, the use of DSUB terminals is recommended, since LEMO terminals do not support
temperature measurement with thermocouples.
