The ST-90 Quad Channel Controller provides simultaneous display and alarm functions for four monitored variables. Easy to configure and user friendly, the ST-90 Quad can function as a critical alarm controller for toxic gases, combustible gases, vibration, tank levels and other process values.

FEATURES

  • Accepts inputs from up to four 4-20mA sensors 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 acknowledged.
  • Two standard SPDT common alarm relays are configurable for HIGH and WARN or FAULT alarm conditions. Optional discrete channel alarm relays are also available.
  • 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 locking of critical configuration variables.
  • Touch and magnetic keypad are standard for non-intrusive operation in potentially hazardous locations
  • Enclosures Include: Non- Metallic, Epoxy Coated Steel, 316 SS, NEMA 4X, 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,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 available (two are standard)
  • 4-20mA outputs, event log, strobe lights and audible annunciators also available
  • 50 and 120 Watt 24VDC power supplies available
