Pem-Tech, Inc. Gas Monitor PT920 Series

Description
Model PT920-16SS is a microprocessor-based modular controller that provides up to sixteen (16) channels of continuous gas detection. The controller is housed in a Nema 4X Stainless Steel enclosure. Each PT920 Series toxic or combustible gas control module can be interfaced with Pem-Tech’s gas sensors. The control modules provide digital display and programmable alarm relay contacts. 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 communication.
