The transducers in series IMX12-SG… are

equipped with intrinsically safe input circuits

and transmit the signals from the connected

strain gauge bridges in Zone 0 to a display or

controller such that the signals are galvanically isolated. Resistive strain gauges can be

recorded using the devices. The devices are

suitable for operation in zone 2.

The IMX12-SG transducers are designed for

1-channel operation and have an input for

connecting strain gauge measuring bridges

of 350…550 ò. The bridge supply is load dependent. The device measures the voltage at

the input and transmits the ratio to the bridge

voltage to the output side. The output signal

is converted to a bridge voltage of 10 V. Analog output 1 can be used as a current output

(0/4…20 mA) or voltage output (1…5 V). The

second analog output (0…20 mV) is externally

supplied with the bridge voltage of 10 V ± 5 V

from a transducer.

The analog outputs and the input circuit monitoring can be configured via DIP switches on

the front.

The devices have a green LED (Pwr) and a

red status LED to indicate faults. An error in

the input circuit causes the red LED to flash

according to NE44. A LOW level is then output at both outputs.

The device is equipped with removable spring

type terminals.
