IOEM Input/Output System Specifications
Input type
There are 4 (IOEM-4) or 8 (IOEM-8) I/O channels that allow digital,
analog (0-1.0VDC, 0-5.0VDC, or 4-20mA) and temperature input
configuration. These inputs are configured to a 5X00 instrument’s
r E-Aux systems allowing for additional instrument inputs. 4-20
mA output channels can be assigned to temperature, pH, ORP,
Conductivity or to Aux and E-Aux input systems.
Each I/O circuit is fully isolated with its own ground.
