Stations for small systems
The CM-10 is a programmable unit used in controlling the site allowing for continuous monitoring in work areas protecting the personnel from dangerous concentration of gas and toxic vapours, simultaneously monitoring up to five different polluting substances.
The unit is extremely compact and in the case of an unforeseeable gas emission of a high concentration (% v/v) alerts the personnel as well as over a longer period of time records efficiently even small gas emissions.
Thus calculating the limits of exposure to TVL, TWA, STEL, CEILLING calculated in PPM or mg/m3.
It is well known that these thresholders represent the maximum levels that can be tolerated by people without provoking any health risks.
The units can be connected to each other or in a loop to a remote PC.
A easy to use object oriented software, is available to create central management and a monitoring unit.
cm20Are control units with sigle (CM-10) or dual (CM-20) input channel designed to operate with 4-20mA transmitters.
- LCD Digital Display 8 characters x 2 lines
- Push-button programming function
- Two settable alarm setpoints
- Relay outputs for Fault and Alarms
- Proportional 4-20 mA Output
- Front panel LEDS for Alarm indications
- Audible alarm indicator (buzzer)
- Serial RS485 Modbus Protocol (CM-20)
CM-80 control units are a series of data acquisition and control modules, for analog and digital signals ideal for small and medium gas detection systems.
Different gas detectors for different gases (including oxygen gas detectors) can be connected to CM-80 control unit. Gas type, detection range, detector full scale, alarm thresholds and relays out puts configuration are programmable by operator. Programming details are protected by Password.
All CM-80 series control panels are extremely well isolated, noise resistant and have n.8 analogue inputs for the connection of a maximum of n.8 gas transmitters 4-20mA.
CM-80 control units have internal stabilized 13.75 Vdc 2.5A Power Supply and output for a 12V, 7.2 A/h back-up battery. A built-in protective circuit controls the battery efficiency, isolating it in case of under or over voltage.
CM-80 can be supplied in “Open Frame” version or installed in a “Wall mounting metal cabinet” with Power Supply included, completely wired and programmed according to specific customers requests.
