SEM1000 - (4 to 20) mA Loop Isolato

The SEM1000 loop isolator is an ideal solution to overcome ground loops. Designed to be series connected into a new or existing (4 to 20) mA current loop and provide an isolated (4 to 20) mA signal capable of driving into 300 ohm. The output is powered from the input loop.

SEM1010 - Provides Isolated Power For A Transmitter Derived From A Powered Loop

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

SEM1015 - Loop Powered Voltage to Current convertor / Isolator

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.

SEM1020 - 4 to 20mA LOOP BOOSTER

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.

SEM1200 - Passive (4 to 20)mA Loop Splitter

The SEM1200 is a current loop splitter that provides two isolated (4 to 20) mA passive outputs from a single passive (4 to 20) mA input.The output loops must be powered externally.

It is housed in a 12.5mm wide DIN rail mount plastic enclosure with screw terminals for wiring. 

SEM1300 MKII - HIGH PERFORMANCE DIN RAIL POWER SUPPLY

The SEM1300 MKII is a high performance switch mode power supply which is 17.5mm wideand which complements our range of DIN rail transmitters  It connects to 100 to 240 VAC  and provides an isolated       24 VDC supply @ 0.5A
