EAGLEHAWK NX CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS

EN1Z-1039GE51 R1218
Analog Outputs
The CLNXxxx26xxx is equipped with four (CLNXxxx14xxx:
two) analog outputs (AOs).
In the event of an application stop (e.g., during application
download), the analog outputs assume the safety positions
configured in COACH NX.
The analog outputs can be configured in COACH NX as
binary outputs (with an output of 0 V or 10 V, as the case may
be).

Binary Inputs / Pulse Counters
Both the CLNXxxx26xxx and the CLNXxxx14xxx are
equipped with four binary inputs (static dry-contact inputs) /
pulse counters (fast totalizers).

Binary Input Specifications
The binary inputs of the EAGLEHAWK NX are static dry-
contact inputs. This reduces the wiring effort, as it is then not
necessary to distribute an auxiliary voltage signal.
open contact
≥ 3000 Ω (24 VDC on BI terminal)
closed contact
≤ 500 Ω (short-circuit current: 2.0 mA)
The polarity (normal = N.O. contact or reverse = N.C. contact)
configuration defines if a logical 1 or a logical 0 is detected for
a closed contact. This is done by selecting (in COACH NX)
one of the following options:
normal (default)
closed external contact → state=1
open external contact →
state=0
reverse
closed external contact → state=0
open external contact →
state=1
Pulse Counter Specifications
Using COACH NX, the binary inputs of the EAGLEHAWK NX
can be configured as pulse counters (fast totalizers) for
operation in conjunction with devices equipped with an open
collector output.
If the duty cycle is 50% / 50%, the pulse counter supports up
to 15 Hz. Counting is done on the rising edge.
