Signal Conditioning

Access Instrumentation is able to supply a range of signal conditioning equipment including signal isolators, trip amps and multifunctional units. In general these devices will take your standard process signals and can provide an isolated 4 to 20 mA re-transmission signal, a single changeover trip relay, twin normally open relays or various combinations.

 Status Instruments SEM 1600VI  Process Signal Isolator/Conditioner

The Status Instruments SEM 1600VI is a “smart” powered isolator/conditioner that accepts any voltage signal between -50 and 50 V dc or any current signal between -50 and 50 mA. The output stage offers either voltage, bipolar voltage or current retransmission signals. The retransmission signal can be ranged to a scale anywhere within the input process range. Transmitter loop power can be supplied to both input and output signals enabling sink or source strategies.

Status Instruments SEM1000 Series Loop Isolators

The SEM1000 series of loop powered analogue signal isolators comprises versions that are suitable for most applications. The small size of the SEM1000 series enables many more units to be installed in the same physical space. They provide high accuracy and can be connected to systems without significantly degrading system performance however zero and span adjustments can be made to remove any unwanted system errors.

 


SEM 1000The SEM1000 signal isolator is designed to be series connected into a new or existing 4 to 20 mA current loop and provides an isolated 4 to 20 mA signal capable of driving into 500 ohms. The output is powered from the input loop.

 

 


imgThe SEM1010 provides isolation between a field mounted, two-wire, 4 to 20 mA transmitter and a PLC type device with a common power supply. The two-wire transmitter connected to the input terminals of the SEM1010 does not require a power supply. The supply required to drive the transmitter is obtained from the power supply connected to the output terminals. Total isolation is maintained between the power supply on the output and the two-wire transmitter.

 

 


imgThe SEM1015 is a 4 to 20 mA isolator that can be configured to accept most of the common voltage ranges found in both commercial and industrial applications. The isolator range can be specified at time of order, but if required the user may re-range the transmitter to a new range.

 

 

 

 


imgThe SEM1020 is a low cost isolator requiring power supply connections on both the input and output terminals. If true isolation is to be maintained, the two power supplies used must be fully isolated from each other. The most common use for the SEM1020 is to provide extra drive capabilities from an existing 4 to 20 mA current loop.

 

 

 

 


imgThe SEM1200 is a low cost isolator that provides two isolated 4 to 20 mA outputs from a single 4 to 20 mA input. The output loops must be powered externally.

    Status Instruments SEM1720  Dual Channel Signal Conditioner for Temperature Sensors

    Status SEM 1720The SEM1720 is a dual channel signal conditioner designed to accept RTD, Thermocouple or Potentiometer sensors and provide isolated, industrial process output signals in mA or Volts. Each output channel may be linked to either input sensor or to a maths function of both sensor signals. This powerful feature allows the device to operate in a number of different modes.
    The output signal can also be adjusted over the full working ranges (0 to 20) mA or (0 to 10) V, to provide common or custom process signals, examples (4 to 20) mA, (0 to 1) mA, (1 to 5)V.

 

 

  • Dual Channel with 5 Port Isolation
  • RTD, Thermocouple or Potentiometer Inputs
  • Universal Voltage and Current Outputs
  • Maths Functions between Channels
  • Probe Redundancy Switching
  • USB Port Configuration
  • 10 Year Warranty
