Description
The unit can accept a signal from any common process
sensors types and give an isolated industrial standard DC
output either voltage or cur rent
DC Cur rent and Voltage
0-20mA, 4-20mA, 0-10mA, -50 to 50mA, into 10Ω
0-1V, 0-10V, 1-5V, -100 to 100V, into 1MΩ
The functionality of the unit is designed to be fully user configurable
via the serial communications by using the RS232 or the RS485
programming lead, complete with the user-friendly PC Smart
software. This software sets up the sensor type and range for the
input signal, the high level output required and any intermediate
processing. The signal processing options featured include:
Ther mocouples
Types E, J, K, N, R, S, T and B all fully linearised
Ranges are user configurable to any values
Auto cold junction comp. Open cct T/ C can drive either upscale,
downscale or to preset value
Resistance Ther mometers
2 or 3 wire Pt100 or other standard type, linearised
Ranges are user configurable to any values
Thermocouple and RTD linearisation
User-defined input linearisation
Square-Root, power 3/ 2, power 5/ 2
Rate limiting
Input filtering
Trip amplifier Functionality
Outputs
DC Cur rent (Source or Sink) and Voltage
0-20mA, 4-20mA, 0-10mA into 1kΩ maximum
0-1V, 0-10V, 1-5V into a minimum 1kΩ
The optional trip relays (UNICONTRIP model) can be configured to
operate in all the normal fail-safe modes. In addition latching and
time-delay functions are also available. A 24Vdc isolated transmitter
supply is featured which can be used to power all standard two-wire
transmitters.
The UNICON is designed to be user configurable, however the units can be
supplied factory configured to your specification – Please contact our sales
department with the following:
The operational status of the unit is indicated by the front panel LED,
a slow flash showing normal operation, a fast flash sensor failure or
open circuit input, or hard off indicating a power supply failure. The
unit may be powered by any DC supply from 16 to 32 volts.
