0–5V Input
A 0–5V throttle input option is also available for the 1204X/1205X/1209/1221
controllers. The negative side of the 5V source should be referenced to B- and
must be capable of driving an input impedance of 5kΩ.
Curtis offers two bi-directional, wigwag electronic throttle assemblies de-
signed for use with the 0–5V input: the ET series and the CH series.
The ET-XXX throttle assembly provides a 0–5V output and forward/reverse
relay coil drivers. Dimensions for the ET-series electronic throttles are shown in
Figure 6. The CH-XXX is a complete control head assembly, consisting of an
ET-XXX throttle integrated into a molded steel and plastic assembly designed for
mounting directly to a tiller stem. For more information about ET and CH
products, contact your nearest Curtis office.
