1.2.6 Transducer Port Input
The Transducer Port input accepts
mulple dierent transducer types.
The Transducer Port input can be
used as a source for the Processes
and Shutdowns (Image 1.2.6).
1.2.7 Thermocouple
Inputs 1 & 2
Thermocouple inputs 1 & 2 accept
k-type thermocouples. They can be
used as sources for the Processes and
Shutdowns. If they are not used they
need to be jumpered (Image 1.2.7).
1.2.8 Modbus RS-485
To use Modbus communicaon,
use the RS-485 PORT on the board,
aaching the A+ and B- wiring as well
as the GND to the external PLC or
communicaon device. Nocaons
of alarms can also be retrieved via
Modbus (Image 1.2.8).
