ES400 – Measurement Modules

Equally at home in the engine compartment (or elsewhere in the vehicle) and at the test bench, the modules of the ES400 product family are designed for installation close to sensors. This minimizes signal distortion that might occur due to long cable runs. The compact module size enables installation even in small areas. The modules are interconnected via Ethernet cables with just one cable connecting the module system to the PC, all of which essentially simplifies setup in a test vehicle or at a test bench.

The rugged module housings and connectors (IP67) are water- and dustproof withstanding acceleration and impact, e.g. from flying rocks. The modules feature a working temperature range of between -40 °C and +120 °C (-40 °F and +248 °F).

Thanks to low temperature coefficients and the electrical isolation of individual measurement and data transfer channels, measurement readings are largely independent of ambient temperature and ground loops.

Why do you need ES400 modules?

In both test bench and road testing, engineers use a multitude of sensors to perform measurements. The ES400 Product Family provides for a scalable daisy chained measurement set-up. This essentially simplifies the installation and interconnection of multiple measuring devices in a test vehicles and at the test benches because

the small and rugged ES400 modules can be mounted close to sensors under the hood
a smart cabling concept makes setup quick and easy and provides for
damage-free keyhole instrumentation of test vehicles.

The ES400 Product Family uses ETAS technology for real time Ethernet data transfer at high rates. The use of an open protocol (XCP) enables the integration of ES400 modules with third party applications, e.g., MM6 (Robert Bosch Chassis Systems Control), DEWESoft (DEWETRON), PROVEtech:VA (MBtech Group), and CANape (Vector). A C-based library is available for integration into software applications that don‘t provide any XCP-on-Ethernet driver functionality. The ES400 series provides optimum support for measurement, calibration, rapid prototyping and test applications.

ES410 – A/D Module

The ES410 is an A/D module with 8 electrically isolated channels. Compared to the ES411 module, it offers 4 additional input channels but no sensor supply. The ES410 module has 8 input voltage ranges between ±100 mV and ±60 V.

ES411 – A/D Module with Sensor Supply

The ES411 module provides four A/D input channels with sampling rates up to 10 kHz. Connected sensors or transducers can be supplied short-circuit proofed with a current of 30 mA per channel at voltages between 5 V and 15 V.

ES413 – Eco A/D Module with Sensor Supply

The ES413 measurement module includes an analog-digital converter for measuring analog signals from sensors or measurement transducers. As Eco model of the ES400 series it combines modern and reliable technology with high efficiency.

ES415 – High Definition A/D Module with Sensor Supply

The ES415 measurement module includes an analog-digital converter for high resolution measurements of analog signals. 4 electrically isolated measurement channels with adjustable and short circuit proof sensor supply are available for measurement.

ES420 – Thermo Module

The ES420 module supports a wide variety of thermocouples to provide for measurements within the desired temperature ranges. With type B thermocouples, temperature values of up to 1820 °C (3308 °F) are accessible.

ES421 – Eco Thermo Module

ES421 is a module for temperature measurement using type K thermocouples. As Eco model of the ES400 series it combines modern and reliable technology with high efficiency.

ES430 / ES432 – Lambda Modules

The ES430 and ES432 Lambda Modules are capable of withstanding the environmental conditions which are typical for exhaust system installations.

ES441 – Counter and Frequency Module

The ES441 module is able to derive multiple types of measurement signals simultaneously from the same physical input – all signals are provided with identical time stamps.
