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.
  • Certified to CSA C22.2 No.152 for combustible detection and Class I, Division 2, Groups A, B, C, and D.
  • Non-volatile memory retains all configuration data indefinitely
  • RS-485 Modbus® master/slave port for up to 128 devices to be multidropped on a single data highway for interrogation by another Modbus® master.
  • Six additional 5 amp SPDT discrete channel alarm relays are available (two are standard)
  • 4-20 mA outputs, event logs, strobe lights, and audible annunciators are also available.
  • 50- and 120-watt 24VDC power supplies are available.
