Digital or Pulsed inputs
Digital Input channel 1 & 2 on the module can be used for a digital ON/OFF switch, a pulsed signal
from something like a Flow Meter or Rain Gauge, or even a Shaft Encoder for measuring level.
Digital Input 3 is a Pulsed input signal only, Maximum Pulsed input rate is 10Hz. For example, a pulsed
signal from a Tipping Bucket Rain Gauge (TBRG), which is a dry contact closure through a small
magnetic switch triggered from a measure of rain fall.
Digital Input 4 can only be used as a Digital ON/OFF input, which could be used for a limit switch or
intruder alarm.
The digital inputs whether a Pulse, Switched or Encoder are activated by connecting the input terminal
to GND or common, either by voltage free contact, TTL level, or transistor switch.
Analog inputs
The module provides two floating differential analog inputs that are capable of measuring 0-20mA
from something like a pressure transducers or sensors.
It should also be noted that the analog inputs can except single ended current sinking or sourcing
devices and can be connected in the top or the bottom of analog loop.
The module also can provide a 24V Analog Loop Supply (ALS) with a maximum of 50mA for any single
ended current loops. To get the best battery life performance the ALS should be configured in the
415U-1-Cx unit to only turn on during the sample period and can also provide a sensor warmup time
before sampling analog value.
The 4-20mA signal is normally used for process variables such as level, pressure, temperature and
flow.
For example, measuring a level using a pressure transducer which detects a pressure at the bottom of
the vessel and produces a 4-20mA output which represents meters of level. As the level rises, the
pressure at the bottom of the vessel increases.
SDI-12 Smart Sensor Input
Smart sensors can be connected using the SDI-12 input. SDI-12 interface is often used with sensors
used for monitoring in environmental, water quality or agricultural applications. The sensor types
include a wide range of parameters such as wind speed, rain fall, air temperature, humidity, water
dissolved oxygen, turbidity, pH, soil moisture, ice on roads and many more.
The 415U-1-Cx SDI-12 smart sensor input can support up to 46 variables and/or sensors on a single
serial channel.
SDI-12 connectivity is shared with the RS-485 communications channel and is not available if the unit
is configured as a Modbus Smart Sensor.
Modbus Sensor Inputs
Smart sensors communication using Modbus RTU RS-485 can be connected to the 415U-1-Cx unit and
their data transmitted to other units or to DCS or SCADA via the Condor wireless network.
Modbus smart sensors can monitor a wide range of process variables, such as pressure, flow and level.
Support for up to 32 Modbus slave devices with up to 46 variables able to be configured.
SDI-12 connectivity is shared with the RS-485 communications channel and is not available if the unit
is configured as a Modbus Smart Sensor.
