- Measuring range: Depends on the used sensor(s)
Design:
- Construction A typical measuring system consists of:
§ MAC 100 multiparameter signal converter
§ 1 (or up to 2) sensors of the OPTISENS series
§ Sensor cable
§ MAA mounting assemblies
- Option The device is available as a one channel (one signal input) or a two channel version (two signal inputs). You can connect one sensor to the one channel version and up to two sensors to the two channel version.
- Sensors For further information refer to the manual of the relevant sensor.
- Also note the table with the sensor input combinations on page 7.
Display and User interface:
- Graphic display: LC display, backlit white 128 x 64 pixels
Note: ambient temperatures below -25°C / -13°F" may affect the readability of the display!
- Operating elements: 4 push buttons for operator control of the signal converter without opening the housing.
- Operating menu:
§ The operation menu consists of the measuring mode and the menu mode:
§ Measuring mode: 4 pages (first and second measuring page with measuring results, status message and trend diagram).
§ Menu mode: variety of main and submenus that allow to customise the device according to the demands of the measuring point.
- Operating and display languages: English, German, (others on request)
- Units: Metric, British and US units selectable as required from lists
Measuring accuracy:

Operating conditions:
Temperature:
- Ambient: -15...+55°C / +5...131°F
Note: the manufacturer strongly recommends to protect the signal converter from external heat sources such as direct sunlight as higher temperatures reduce the life cycle of all electronic components.

Other conditions:
- Humidity (ambient): Max. 90% at 40°C / 104°F
- Pressure: For information about the process pressure of the used sensor(s) refer to the relevant sensor documentation!
- Protection category acc. to IEC 529 / EN 60529: IP66/67 (acc. to NEMA 4/4X)
Installation conditions:
- Installation: Only wall mounting is possible, always assure a vertical mounting orientation!
- Dimensions and weights: For detailed information see chapter "Dimensions and weights".
Materials:
- Signal converter: housing Die-cast aluminium (polyurethane coated)

- Inrush current IN, eff = 97 mA, t15 = 1.5 ms, tPeak = 200 µs, Ipeak = 22.6 A
- Cable entries:
§ 1 channel: 4 x M20
§ 2 channels (separate temperature sensor): 3 x M20, double PG two times 5 mm / 0.20" screwed connection for sensor cables
§ 2 channels (integrated temperature sensor): 3 x M20, double PG two times 8 mm / 0.31" screwed connection for sensor cables
Inputs and outputs:
- General: All in- and outputs are electrically isolated from each other and from all other circuits. All operating data and output values can be adjusted.
- Description of used abbreviations: Uext = external voltage; RL= load + resistance; Uo = terminal voltage; Inom = nominal current
Inputs:
- Sensor inputs: Up to 2, depending on the version. For further information refer to the manual of the relevant sensor.
- Control input:
§ Passive, not polarity sensitive, Uext, max ≤ 32 VDC, Inom = 6.5 mA with Uext= 24 VDC, Inom = 8.2 mA with Uext= 32 VDC
