SEM1603i

The SEM1603i is a isolating current loop convertor. It accepts any input between (-10 to 25) mA, even inverted inputs, and provides the user with a standard two wire (4 to 20) mA output signal. Isolation is provided between input and output.

Typical uses include providing extra drive capability for an exisiting current loop and providing signal scaling and inversion. The input only needs 54mV from the loop. Click here for datasheet

  • Accepts any mA input between (-10 to 25) mA
  • Signal Inversion Facility
  • Provides Extra Drive For An Existing Current Loop
  • Only Takes 54mV From The existing Current Loop
  • Configured with USB port powered configuration module

SEM1010

The most common use of the SEM1010 is to provide 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. Click here for datasheet

  • Provides Isolated Power For A Transmitter Derived From A Powered Loop
  • Transmitter Powered from the Output Of The SEM1010
  • Galvanic Isolation
  • High Reliability

SEM1015

The SEM1015 is a (4 to 20) mA loop powered isolator that can be configured to accept  voltages between -10 and 100V DC. The voltage range can be specified at time of order, but if required the user may re-range the transmitter to a new range.

The isolator is housed inside a 12.5mm wide plastic enclosure, suitable for DIN Rail mounting. Screw terminals are provided for wire connections. The enclosure provides side entry access to coarse offset and span adjusters and a range select switch. Click here for datasheet

  • Accepts any DC Voltage Input Between -10 and 100VDC
  • Loop Powered 4 to 20 mA Output
  • Can be used as adder or subtractor
  • High Accuracy
  • Galvanic Isolation

SEM1020

The SEM1020 is a loop isolator designed to provide extra drive capability from an existing current loop. It requires 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 input circuitry only drops 2.7 V from the existing current loop and providing a 24 V isolated power supply is used on the output side, the isolator will drive up to 900 ohms. The most common use for the SEM1020 is to provide extra drive capabilities from an existing (4 to 20) mA current loop.

  • Provides Extra Drive Capability From An Existing Current Loop
  • Only Requires 2.7 V From the Existing Loop
  • Galvanic Isolation
  • High Accuracy
