The
LAN-4422 is designed for professional integration in industrial
machinery, office- or household devices. DIN-rail housings are
available, to use the LAN as a “stand-alone” controller.
The
board provides 2 opto-isolated and 2 TTL inputs. These inputs can be
used as counter inputs. Counter-states and actual frequencies can be
read out wirelessly, which makes it most suitable for metering
applications like electricity, gas, water meters.
Digital
outputs comprise 2 Relays and 2 TTL outputs. Digital Outputs can be
switched remotely. A time off -delay may be parameterized to switch
off the outputs when connection to the board is lost.
The
LAN-4422-provides 2 analogue outputs. Each of those outputs are
provided as both a voltage signal in the range of 0-5 VDC and as
pulse-width modulated TTL (PWM) signal. There are also 2 0-5V
analogue inputs.
On/Off
Control
The
LAN-4422 provides 2 independent on/off controllers. Each controller
consists of one analogue input and one relay output. The actual
output of the plant is captured by the analog input and compared with
the defined switching points.
PID
Control
The
LAN-4422 provides 2 independent PID controllers. Each controller
consists of one analogue input and one analog output. The actual
output of the plant is captured by the analog input an processed by a
PID-algorithm. The controller then generates an output signal at the
analogue output. PID parameters are user adjustable.
