3.6.1.3 CAN-IN-OUT-MSC
3.6.1.3.1 Functions
The function of the CAN-IN-OUT-MSC board is to provide I/O functions,
which are necessary to control the enhanced loading and additive
injection processes.
Following are the functions of the CAN-IN-OUT-MSC board.

Function Description
3 Digital Input AC (DI-AC) circuits Converts high voltage switched AC signals into an isolated logic signal
that can be read by the FlexConn generic microprocessor.
15 Digital Input DC (DI-DC) circuits Converts switched DC signals into an isolated logic signal that can be
read by the FlexConn microcontroller.
Analog Output (AO) circuit Converts signals from the FlexConn microcontroller into scaled 4-20 mA
analog signals.
4 Digital Output Solid State Relay AC (DO-
SSR AC) circuits
Converts logic signals from the FlexConn generic microcontroller into
isolated, high voltage switched AC signals.
4 Digital Output Solid State Relay AC/DC
(DO-SSR) circuits
Converts logic signals from the FlexConn generic microcontroller to
switched high power AC or DC signals.
