Technman Electronics Ltd - Control-it 5050

By: Technman Electronics  06-Dec-2011

Allows remote reading of temperature, voltage, and current. This unit also comes with the option of two 4-20mA outputs.

Designed for:
  • Remote Data Acquisition
  • Industrial Process Control
  • Transducer - Signal, Weight, Pressure, Flow, Voltage, Current and Temperature measurement
  • Process control with 4-20mA output

Some Benefits of the 5050 Analogue/Digital Controller:

Saves Time:

  • Standard screwdriver connection to your wiring - no soldering or crimping needed
  • Hot-swapping of I/O devices makes troubleshooting hassle free

High Performance:

  • Can be set to run at 3 times the speed of other units (such as the OPTO22), delivering improved accuracy of process response
  • Rejects 50Hz and 60Hz hum
  • 15 bit accuracy at 10 samples/sec


  • Can be controlled from the serial port of any PC or laptop computer using the Control-it 5001 RS232-485 converter
  • Supports the industry standard OPTO22 communications protocol and inexpensive RS485 two wire network
  • Can measure 0-1V, 0-10V, 0-20mA plus J, K and T temperature probes.
  • Each analog input can be configured for a different type of input.

Easy to Install:

  • Panel or DIN rail mountable, or can be stacked with a special stacking kit
  • Well labelled, robust enclosure for easy installation
  • Can be used with most standard power adaptors
  • Comms and power connectors can be unplugged


  • Fully floating circuitry protects your computer from power spikes
  • Microprocessor controlled watchdog feature disables all outputs in event of processor failure

Built -in Reliability:

  • Designed to exceed international standards for noise immunity
  • Complete isolation of all comms and I/O sections minimises outside interference errors
  • 5 LEDs and a comprehensive trouble-shooting guide for easy diagnosis of suspected system faults
