The SEM1000 ground loop isolator is 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 Ω maximum load. The output is powered from the input loop.
This ground loop isolator requires no user adjustment during commissioning. Minor adjustments can be made to the calibration of the device by means of the two front panel accessible calibration potentiometers.
Incorrect connection in the loop will not damage the device as long as the specified maximum currents/voltages are not exceeded.

This loop-powered voltage isolator can be configured to accept most of the common voltage ranges found in both commercial and industrial applications between the range. The input is fully isolated from the output circuit. The loop-powered voltage isolator range can be specified at the time of order, but if required the user may re-range the transmitter to a new range. The Isolator is housed inside a plastic enclosure, suitable for DIN rail mounting. Screwterminals are provided for wire connections. The enclosure provides side entry access to coarse offset and span adjusters and a range selector switch.

The loadcell amplifier SEM1600/B is a “smart” powered bridge loadcell amplifier for use with load cell signals. The product has a built in capability to scale the input signal to a process value while the output stage offers either voltage, bipolar voltage or active / passive current re-transmission signals.

The product comes with an AC/DC power supply that will operate in the range (10 to 48) V DC and (10 to 32) V AC making the device ideal for battery operation. An additional volt-free contact input is available for tare setting using a remote switch. The high precision input stage of the device allows for a bridge excitation voltage of 5V DC to be used as opposed to the traditional 10V DC. This reduces the power requirement for the bridge supply and up to four bridges (cells) may be connected to the input.
