Installing the AppController

Inputs

The AppController has 6 inputs that accept the following signal types.
These
inputs...
All
All
IN-1, IN-2
All

Binary outputs

The AppController has 5 binary outputs. You can connect each output to a maximum of 24 Vac/26 Vdc. Each
output is a dry contact rated at 1 A, 24 V maximum and is normally open.
To size output wiring, consider the following:

Total loop distance from the power supply to the controller, and then to the controlled device
NOTE Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.

Acceptable voltage drop in the wire from the controller to the controlled device

Resistance (Ohms) of the chosen wire gauge

Maximum current (Amps) the controlled device requires to operate

Analog outputs

The AppController has 3 analog outputs that support voltage. The controlled device must share the same ground
as the controller and have the following input impedance:
0–10 Vdc Minimum impedance 2000 Ohms, max 5 mA
NOTE Ohm's law: -10V/.005a = 2000 Ohms

Support this signal
type... Description
Thermistor Precon type 2 (10 kOhm at 77°F/25°C)
Input voltage for IN-5: 1 to 2.52 Vdc
Input voltage for all other inputs: 0.33 to 2.52 Vdc
Dry contact A 3.3 Vdc wetting voltage detects contact position, resulting in a 0.3 mA
maximum sense current when the contacts are closed.
0–5 Vdc The input impedance of the AppController is approximately 30 kOhm.
Pulse counter Pulse counting up to 10 pulses per second.
Minimum pulse width (on or off time) required for each pulse is 50
msec.
