The EM2 provides plant personnel an at-a-glance visual indication before entering potentially dangerous areas. Simple menu-driven programming through the LCD operator interface, and one relay output with adjustable alarm setpoint. Great for engine rooms, air handlers, and stand-alone applications.
The EM2 can be used as a stand-alone monitor or in series with the sensor signal to provide remote display / remote relay operation. As a feedthrough device, the sensor signal is re-transmitted back to any industry standard 4/20 mA device such as a PLC or gas detection control panel.
The watertight polycarbonate enclosure will stand up to corrosive washdown, temperature swings, and any other harsh environment encountered in the food industry. The electronics are completely potted to protect against corrosion, allowing for installation
in washdown areas and outdoors.
The EM2 is a low cost solution that provides multiple configurations to meet many needs for remote display and alarm applications. Use the EM2 as a stand-alone device, or a feedthrough device to provide remote display and alarm output capability located at or near the sensor.
Since sensors often end up in wet and harsh environments, an onboard relay is not always ideal.
The EM2 provides alarm activation remote of the sensor, in a safe enclosure out of harm’s way. The onboard relay is rated at 5A @ 24VDC or 8A @ 120VAC.
The EM2 provides an at-a-glance indication of dangerous gas concentrations with a large LCD. Alarm indications are displayed by a flashing ALARM status on the LCD. Calibration mode, Test mode and analog In/Out Adjust mode are handy features of the operator interface.
The EM2 also includes a sunshield which can be installed for UV protection to prolong the life of the LCD display.
