4-20 mA
e inputs support self-powered 4–20 mA sensors. Input
accuracy is ±2% of span, without user calibration. Use a
499 ohm resistor wired across the input terminals.
Caution: When using an externally powered 4–20
mA sensor, be sure to de-energize its power supply
before making or changing any wiring connections to the
Edge-10 module. is is in addition to removing power
from the Edge-10 module. DO NOT apply external
power to the UI inputs without the 499 ohm resistor in
place. Otherwise, even a momentary application of power
(say, 24Vdc) to the UI terminals without the resistor may
damage circuitry on the Edge-10. Only aer completing
all input wiring should you restore power to such external
power supplies.

Binary Input
e universal inputs support normal dry (equipment
status) contacts. Standard dry contacts must have a 1 Hz.
(or less) COS frequency, with minimum dwell time >
500ms. (Contacts must remain open at least 500ms and
be closed at least 500ms.) Dry contacts support 11 Vdc
open circuits or 733 µA short-circuit current.

Outputs
e Edge-10 provide 3 triac digital outputs and 2 0-10Vdc
analog outputs
Binary Triac Outputs
Each digital triac output is rated at 24 Vac +/- 15%,
50/60Hz, at 0.5A max. Relays are not rated for AC mains
(line level) powered loads (instead, 24V maximum).
Outputs are normally open, oating and do not share a
common pin.
NOTE: Triac outputs are suitable for AC only. DC loads
and dry contacts require an intermediate relay.
Warning: Never use a controller’s power transformer
to power I/O loads. Using the controller’s transformer
introduces potentially damaging switching transients into
the unit.

Analog Outputs
Analog outputs (AO) are referenced by the terminals
labeled AOn and 0V (ground). Each AO can supply a
maximum of 4 mA over the entire 0 to 10Vdc range. e
minimum input impedance of a device controlled by an
AO must be greater than 2500 ohms.

Power up and Checkout
Power Up and Initial Checkout
1
Apply power by inserting the 2-position 24V power
connector plug.
2
Check the green STAT (Status) and yellow BEAT
(Heart- beat) LEDs.
When power is applied, the green “STAT” LED will light.
is indicates the system is OK, with power applied.
During bootup, the “BEAT” LED may blink at 3 Hz with
a 50%/50% on/o duty cycle. When bootup completes,
the platform daemon is started, and the normal 1 Hz
ash at 50%/50% on/ o duty cycle of the “BEAT” LED
returns.
