Engine Sender Inputs chapter. The fuel level input accepts resistive senders only. Oil pressure and
coolant temperature inputs accept either resistive or analog senders depending on the style number.
Engine sender input terminals are listed in Table 7.
Table 7. Sender Input Terminals
Terminal Description
71 (FUEL +) Fuel level sender input
72 (FUEL –) Fuel level sender return
74 (OIL + / ANALOG IN 4 +) Oil pressure sender input or Analog input 4 +
75 (OIL – / ANALOG IN 4 –) Oil pressure sender return or Analog input 4 –
76 (N.C. / ANALOG IN 4 I) Analog input 4 (I) current input
∗
77 (COOLANT + / ANALOG IN 3 +) Coolant temperature sender input or Analog input 3 +
78 (COOLANT – / ANALOG IN 3 –) Coolant temperature sender return or Analog input 3 –
79 (N.C. / ANALOG IN 3 I) Analog input 3 (I) current input
∗
∗When using the current input, it must be tied to the voltage input. See the Typical Applications
chapter for a diagram.
Analog Inputs
Two user-programmable analog inputs are provided. These inputs accept a signal range of either 4 to
20 mA or 0 to 10 Vdc. Analog input terminals are listed in Table 8.

Terminal Description
80 (ANALOG IN 1 +) Auxiliary analog 1 +
81 (ANALOG IN 1 –) Auxiliary analog 1 –
82 (ANALOG IN 1 I) Auxiliary analog 1 (I) current input
∗
83 (ANALOG IN 2 +) Auxiliary analog 2 +
84 (ANALOG IN 2 –) Auxiliary analog 2 –
85 (ANALOG IN 2 I) Auxiliary analog 2 (I) current input

∗When using the current input, it must be tied to the voltage input. See Typical
Applications chapter for a diagram.
Magnetic Pickup Input
The magnetic pickup input accepts a speed signal over the range of 3 to 35 volts peak and 32 to 10,000
hertz. Magnetic pickup input terminals are listed in Table 9.
Table 9. Magnetic Pickup Input Terminals
Terminals Description
105 (MPU–) Magnetic pickup return input
106 (MPU+) Magnetic pickup positive input
Contact Sensing Inputs
Contact sensing inputs consist of sixteen programmable inputs. The programmable inputs accept
normally open, dry contacts. Terminal 49 (BATT–) serves as the common return line for the
programmable inputs. While input 1 is programmed to recognize an emergency stop input by default, it
can be programmed for any function. Information about configuring the programmable inputs is provided
in the Contact Inputs chapter. Contact sensing input terminals are listed in Table 10.
