Model PT900-6XP is a microprocessor based modular controller suitable for use in Hazardous locations. Maximum of six (6) PT900 Series toxic or combustible gas control module can be interfaced with Pem-Tech's gas sensors. The control modules provide digital display, discrete 4-20mA analog output and programmable alarm relay contacts. The low power RISC based microprocessor allows all the alarm levels and control module address programmed via switches on the front panel. The bright LED display indicates the gas concentration. Also features amber and red LED indicators for alarm status. One of the safety features is a flashing digital display when the control module is in alarm bypass mode. The flashing display is an indication to the personnel in the control room about the alarm bypass status. Each control module has RS-485 MODBUS RTU serial communication compatible with PLC's, SCADA, and DCS systems. The module provides complete status like current gas concentration, sensor calibration and current alarm status. The alarm levels can also be accessed and programmed via MODBUS.
