by RC Systems
The ViewSmart 400 is a 4-channel Alarm Controller which provides simultaneous display and alarm functions for four monitored variables. Easy to configure and user-friendly, it functions as a critical Alarm Controller for toxic and combustible gases, vibration, tank levels and other process values.
Features:
- Accepts inputs from up to four 4–20 mA sensor transmitters for long distance interfacing. Generates 24VDC external device power for transmitters and other devices
- Three adjustable independent alarm levels per channel. “Relay Acknowledge” feature allows silencing of external audible devices during existing alarm conditions.
- Graphic LCD readout displays monitored data as bar graphs, engineering units, and 30-minute trends. Alarm LED’s flash when new and become steady after acknowledgment.
- Two standard programmable SPDT alarm relays are configurable for HORN, HIGH, WARN or FAULT alarm conditions.
- Modbus® master/slave RS-485 serial port interfaces to Modbus® devices such as PCs, PLCs, DCS, and other RC Systems controllers.
- Cal Mode offers pushbutton zero/span calibration for direct sensor interface applications.
- Authorization mode allows the locking of critical configuration variables.
- Touch and magnetic keypads are standard for non-intrusive operation in potentially hazardous locations.
- Enclosures Include: Non-Metallic, Epoxy Coated Steel, 316 SS, NEMA 4X, and NEMA 7 Explosion-Proof Wall Mount Packaging options available.
