Digital weight indicator GAMMA-M

panel-mount4-20 mA0-10 V

Summary
The GAMMA-M indicator is a measurement and control instrument with direct reading in process units, designed to handle a wide range of input signals and capture fast values through high-frequency conversion.

Accepted inputs

• Load cells: mV/V, mV
• Process: ±10 Vdc, ±20 mA
• Potentiometer (displacement sensors)

Sensor supply voltages (selectable via internal jumpers)
24 V (30 mA), 2.2 V (30 mA), 5 V or 10 V (120 mA) — capacity for 4 load cells.

Performance

• Conversion speed: 555 Hz (readings: 555/s)
• Allows detection of peaks and minima with a minimum duration of 2.1 ms
• Resolution: ±15 bits
• Dimensions (mm): 96 x 48 x 120

Outputs and communications options

• Optional analog outputs: 0–10 V or 4–20 mA (200 readings/s)
• Relay outputs: 2 or 4 setpoints, or 4 optocouplers, response time 2.1 ms
• Communication: RS232C or RS485 (DITEL, ISO1745 and MODBUS-RTU protocols)

Signal processing
Programmable processing via 3 filter types for stabilization and adaptation to process requirements.
