Filter searchAD-SMK 340 GVD
Description
The limit switch AD-SMK 340 GVD compares the measuring value of a 2- or 3-wire-transmitter at the input with the preset values. If the measuring signal exceeds the set value, or is below it, the relevant output relay reacts according to the preset function. The standard signals (4–20mA, 0–10V) are possible as analogue input value without additional switch-over. The limiting values must be set at the keys 0–99% at the front. The output functions 2max, 2min or 1max/min as well as the resting or working principles of the output relays are also adjustable at the front. With operating mode 2max/2min, the hysteresis at both channels is approx. 1%. Input, outputs and the supply voltage are galvanically sepa- rated from each other.
Application
Monitoring and signalling of limiting values of analogue measuring signals such as through flow, height levels, temperature etc.
Specific characteristics
- Transmitter feeding voltage.
- Two limiting values, digital freely adjustable up/down keys at the front.
- Indication of limiting values and relay condition via LED at the front.
- 23 mm wide serial housing with connection terminals, which can be pulled off.
