Universal Isolating Amplifier, TV125L
- safe galvanic isolation between input/output/auxiliary voltage
- step response T90: 40ms
- output deviation <0.2% of the limit value
- overload protection of the current input with automatically resetting fuse
- operating display and status messages via two-colour LED
- configuration via front DIP switches
- plug-in terminal strips
- slim installation width of 12.5mm for carrier rail mounting TS 35
This isolating amplifier is suitable for potential isolation or for conversion of industry standard signals. The universal layout of the inputs and the output enables a broad range of applications with only one type of device. The plug-in terminal strips enable simple and time-saving wiring. The configuration is also quick and easy with the front DIP switches.
The input measuring ranges can be switched between 0...20mA and 4...20mA or 0...10V and 2...10V with a DIP switch on the front.
With the microprocessor-controlled measurement logging, undercutting and exceeding of the measurement range are detected and indicated via a two-colour status LED on the front side. Furthermore the current output is set to a defined starting or final value.
The current input is protected with an automatically resetting fuse (PTC) against static overvoltages up to 32VAC/DC.
The required auxiliary energy is less than 0.5VA.
The three circuits: Inputs, outputs and auxiliary voltage are galvanically separated with strengthened isolation.
