Analog Input Connections
DGC-2020HD controllers with style number xxxxxxxxR are equipped with two analog inputs and those
with style number xxxxxxxxA are equipped with four analog inputs.
Voltage and current analog input connections are shown in Figure 10. When using the current input, the
“+” and “I” terminals must be tied together.
Figure 10. Analog Engine Sender Voltage Input Connections
CAN Connections
Typical CAN connections are shown in Figure 11 and Figure 12 .
Note
1. If the DGC-2020HD is providing one end of the J1939 bus, a 120
Ω, ½
watt terminating resistor should be installed across terminals 51 (CAN1L)
and 52 (CAN1H) or 54 (CAN2L) and 55 (CAN2H).
2. If the DGC-2020HD is not providing one end of the J1939 bus, the stub
connecting the DGC-2020HD to the bus should not exceed 914 mm (3 ft)
in length.
3. The maximum bus length, not including stubs, is 40 m (131 ft).
4. The J1939 drain (shield) should be grounded at one point only. If
grounded elsewhere, do not connect the drain to the DGC-2020HD.
