GPIO Pin-Out Details
The CAB4n Series include a versatile GPIO (General Purpose Input Output) system for
terminating external logic, controls, relays and other external systems. Each control pin is
supported by NWare for configuration, control and monitoring. Any combination of control pins
may be used simultaneously, regardless of the configuration. For information on the GPIO
configuration options, please refer to the NWare Help, included with the software.
The GPIO system provides the following features:
Configurable General Purpose ports (8 Control Pins)
These ports represent the bulk of the CAB4n GPIO functionality. Each of these ports can be
configured as follows via the *NWare software CAB4n properties block:
- Digital In (3.0V TTL logic - Low: 0VDC - 0.8VDC; High: 2.0VDC - 24VDC)
- Digital Out (3.0V TTL logic - Low: 0VDC - 0.4VDC; High: 2.4VDC - 3.3VDC)
- Analog In, self powered (pin feeds required voltage through pot or switch to common)
- Rotary Encoder (requires 2 pins and a common)
NC & NO relays (4 Sets)
4 sets of normally open or
normally closed relays are
available for general purpose
usage. User configurable within
the *NWare design program
file.
Fault relay
A single system relay is
configured for supervising
project faults. This Form C
relay provides 1A contacts and
is activated when the front panel
fault LED is illuminated, which
indicates a muted condition.
