levels with a drive capability of 1 LS load. The Option BCD may be used to drive the Valhalla Model 1248.
(See Chapter 8)
Option RS232: Data Output
The interface is isolated to 2.5kV on both power and Data lines and uses iCoupler Technology. Option RS-
232 provides a safe way to communicate with the Alpha 4314 via a computer or PLC and allows the
transfer of single readings or continuous transmission of data. This interface is for data acquisition only
and does not provide range control
