In-line Strain Gauge or Load Cell Analogue Amplifier in IP54 EnclosureILA
Description
The Mantracourt ILA is a compact, IP54-rated signal conditioning amplifier that converts strain gauge bridge inputs into a high-stability 4–20 mA analogue output. Designed for integration in space-limited installations, it offers fast setup via the ILA Toolkit and programming module.
The ILA provides excellent EMC protection and features dual 256-step non-volatile digital potentiometers for semi-automatic gain and offset calibration. Compatible with a wide range of sensors including load, pressure, and torque transducers.

| Supply Voltage Range | 9 to 32 V (note 1) | For 12 V operation the maximum receiver input impedance is 400 ohms. Operation at lower supply voltages is possible but limited by receiver’s input impedance e.g. for operation at 10 V the receiver’s input impedance should not exceed 250 ohms or 150 ohms for 8 V operation |
| Operating Current | 8 mA (note 2) | Not including excitation current and output current e.g. when connected to a 350 Ohm load cell:- Total current = Operating current (8mA) + Excitation current (5/350 = 14mA) + Output current (20 mA FS) = 42 mA FS (typical). |
| Operating temperature range: | -40 to 85 ºC | |
| Storage temperature range | -40 to 85 ºC | |
| Reverse polarity protection (power supply, input and output connections) |
-30 V | |
