Description
Controller units with modular design, remote sensors, and dual-channel capability offer
a variety of configurations to meet most applications.
Units operate with a complete range of gas sensors and transmitters including toxic, combustible, and oxygen sensors.
Flexible Options for Reliable System Control
۹۰۱۰/۹۰۲۰ Controllers offer maximum flexibility to work in conjunction with remote sensors to provide reliable gas detection for many industries and applications.
Advanced design using SMD components throughout plus innovative features put the 9010/9020 LCD Control Units steps ahead of any conventional gas warning system.
The 9010 LCD Controller operates with 1 independent sensor (single-channel) while the 9020 LCD Controller operates with 2
independent sensors (dual-channel) per control module, offering considerable cost savings while maintaining high reliability and performance.
Modular design combined with dual-channel capability allows for many configurations to meet most applications.
Each control module comes with an independent AC/DC power supply transformer for increased system reliability.
Each module has 2 (SPDT) relays with change-over contacts for verification of Warning and Alarm conditions (common to both channels in the 9020 version).
Full internal diagnostics and inherent reliability minimize false alarms and unexpected down-time.
A customized transmission protocol Modbus RTU can be used for serial bus data transmission such as system configuration,
gas concentration, alarm and failure events, alarm inhibit, and reset.
The 9010/9020 LCD Controller can power remote sensors (by constant current or voltage), enhancing the systems’s versatility.
These user-friendly, configurable control modules adjust through code access with no tools required.
Liquid Crystal Display
Large, 4-digit, 7- segment, back-lit LCD and bright LED provide gas concentration, alarm status, measurement units,
flags indicating status, and settings such as calibration interval, time-out function, alarm ON delay, and alarm inhibit.
TWA-STEL
When operating in connection with toxic sensors, the 9010/20 LCD Controller can be set to alarm when relevant STEL and TWA values are exceeded.
Sensor Wiring
Remote sensors are factory-set to 2-or 3-wire connection, depending upon specific application.
