Axiomatic 18 Digital Input
The Axiomatic 18 Digital Input is a CANopen compliant [DS-301] input module with a configurable
selection of input types. The object dictionary is compatible with the CiA DS-404 device profile.
(device profile for measurement devices and closed-loop controllers.) In addition to the standard
objects for this device profile, the 18 Digital Input also includes a number of manufacturer specific
objects to extend the functionality beyond that of the basic profile.
The module includes the following inputs:
Eighteen (18) digital inputs (
DI1 to DI18)
that can be configured (using a CANopen object) as
one of the following:
o
Active High input (where a +V is = ON and 0 V = OFF)
o
Active Low input (where a 0 V is = ON and +V = OFF)
Inputs 1 to 8 (
AI1 to AI8)
are the only software configurable inputs that can be individually
configured (using a CANopen object) as one of the following types:
o
PWM
[0-100%]
o
Frequency [0 to 10kHz]
o
16-bit Counter
Refer to the appendix for full electrical specifications of the inputs.
