Signal amplifier 125M series

powercurrentvoltage

conly one type of device. Alternatively the power supply can be carried out via a mounting rail bus connector. The pluggable terminal strips allow a simple and time-saving wiring. The configuration of input and output signals is done by front panel dip switches in a very easy and fast way. Because of the microprocessor design it´s possible to interpret under- or overshooting the measurement range and indicate by a bi-color status LED on the front panel. In case of an error the output is then set to a defined initial value or ending value. The initial value and the end value of the measuring range can be adjusted by means of two front-mounted trimmers. The device version of ST125 additionally provides a transmitter power supply for external 2-, 3- and 4-conductor sensors. ●Potential separation, conversion, supply and adjustment of standard signals (mA, V ↔ mA, V) ●Functional safety up to SIL2 ●Supply of 2-, 3- or 4-wire transmitters (ST125M) ● Intrinsically safe types for zone 0/20 ● Installation up to zone 2 ●Minimized type variants due to wide-range power supply ●Efficient wiring with scale-able Power Rail-devices ●Short downtime due to clear indication ●Fast commissioning due to front sided controls ●Plug-able, coded and numbered terminals for reliable and interchange-proof wiring
