Inputs; Digital Outputs - Automated Logic SE6166 Technical Instructions

Inputs

The SE6166 has 16 inputs that accept the signal types described below.

IN-1, IN-2
IN-1, IN-2
IN-9, IN-10
1 To use a thermistor or RTD not listed above, you can set up a custom translation table (page 19)
for your sensor.
2 The SE6166 can perform pulse counting for dry contact or voltage inputs if you assign the input to
a Pulse to Analog Input microblock. See To assign inputs or outputs to points (page 13).
3 A LogiStat or LogiStat Plus connected to the SE6166 uses IN-9 and IN-10. A LogiStat Pro or an RS
room sensor does not use these inputs.

Digital outputs

The SE6166 has 6 digital outputs. You can connect each output to a maximum of 24 Vac.
Each output is a dry contact rated at 3 A maximum and is normally open.

signal type... Description
Thermistor Precon type 2 (10 kOhm at 77°F). Input voltages should
1
be from 0.489 Vdc to 3.825 Vdc for thermistors.
Dry contact A 5 Vdc wetting voltage detects contact position, resulting
in a 1 mA maximum sense current when the contacts are
closed.
0–5 Vdc The output impedance of a 0–5 Vdc or a 0–10 Vdc source
0–10 Vdc must not exceed 200 Ohms. The input impedance of the
SE6166 is approximately 20 kOhm.
0–20 mA The input resistance on the positive (+) terminal is 250
Ohms. The Aux Power Out connector is capable of
supplying 24 Vdc to multiple 4–20 mA transducers, but
the total current demanded must not exceed 200 mA. If
the voltage measured from the Aux Power Out connector
to Gnd is less than 18 Vdc, you need to use an external
power supply.
RTD Platinum - 1 kOhm at 32°F (0°C)
1
Nickel/Iron - 1 kOhm at 70°F (21°C)
Balco TS8000 - 1 kOhm at 70°F (21°C)
Input voltages should be from 0.6–1.2 V.
NOTE ALC recommends use of an external current
transducer between an RTD and the SE6166.
Pulse Pulse counting up to 40 pulses per second.
counter Minimum pulse width (on or off time) required for each
2
pulse is 12.5 msec.
Timed local A momentary contact switch that overrides a schedule and
override turns equipment on for a defined period of time. The
override time added for each push of the button and the
maximum allowable On time are software adjustable.
LogiStat IN-9–See Thermistor.
LogiStat Plus
3
IN-10–Setpoint adjust. Input voltages should be from 1.4–
3.4 Vdc.
