SCHALTVERSTÄRKER 521
ELECTRONIC ACCESSORY | DISPLAY AND CONTROL DEVICES
The switching amplifier is preferably used for binary signal transmission of water meters.
The switching amplifier is frequently used as pulse extension relay for fast running processes. It can be used as contact protection relay or non-bounce relay when being triggered by a volt-free contact transmitter (reed switch).
If required, the two binary inputs can be added to one output-channel (via turn switch).
- Snap-bar case version
- Triggered on choice by contact transmitter, infrared transmitter and two-wire primer (NAMUR)
- Each output is a opto-coupler with one no-contact
- Two volt-free outputs, solid state relay, no-contact
- Galvanically isolated measurement and supply circuits
- Adjustable impulse period
- 3 different pulse length, adjustable via turn switch
- Pulse-addition adjustable via turn switch
- Power supply 20 ... 250 V AC/DC
