4.8 Option 8 – Analog Output/Relay Option
NOTE: Option 8 only addresses the setup of the analog output section on the dual function circuit board.
Option 8 utilizes the KJN8924, a dual function circuit board mounted internally to the back plate of the indicator. It
provides a four relay output for setpoint process control and a 4 - 20mA or 0 - 10 VDC analog output which is
configured and trimmed for zero and span in similar fashion as the older option 2 analog output (KHD8924).
Besides its dual function capabilities, the board uses a 16-bit DAC.
Table 4-16 shows the Option 8 configuration.
Table 4-16. Option 8 Configuration Parameters
Refer to Section 4.12.3 on page 46 for individual serial command option parameters for Option 8.
4.8.1 Analog Output Option Wiring
Table 4-17 and Figure 4-12 show the analog output wiring.
Table 4-17. Analog Output Wiring
Ribbon Cable Connection
The ribbon cable is a sixteen conductor cable that connects the TTL control logic levels (inputs and outputs) on J11
of the CPU board KGR8924 to J1 on the analog/relay option board.

Enter weight value for analog Zero using the numeric keys. The TARE key will store new
value, while the display responds with Enter.
8.3 FS Use the same procedure as 8.2 to enter the analog Full Scale value.
8.4 Zr.A Zero Trim, while measuring the analog output, use the lb/kg CONV and PRINT keys to
increase/decrease the zero value. Increase/decrease function forces a test mode zero
output. The
TARE key stores the new value.
8.5 SP.A Span Trim, same as 8.4 except a span test mode output is provided.
