Hardware Description ETAS
3.5 Analog Inputs
The ES5340.2-M has four inputs for measuring analog signals.
3.5.1 Specification
The operating voltage range for two inputs is 0 to 5 V, with two additional
inputs, it is 0 V to +40 V. All inputs are galvanically isolated and have an elec-
tric strength of ±60 V – the impedance of the inputs is 1 M
Ω
.
The sampling rate is 500 kSamples/s (software averaging is possible using 2
n
(n =1 to 8) samples) at a resolution of 12 bits.
3.5.2 Configuring the Analog Inputs
The analog inputs can be used to measure battery voltages and other constant
voltages (control signals).
The type of averaging used for the detected signals can be configured in LAB-
CAR-RTC in the "ES5340-Analog-In" item of the "Globals" tab.
3.6 Digital Inputs
The ES5340.2-M has 20 inputs for measuring digital signals.
3.6.1 Specification
The operating voltage range is 0 to +60 V. All inputs are galvanically isolat-
edgalvanically isolated and have an electric strength of ±60 V.
The maximum input frequency is 125 kHz, and the resolution is 8 ns
(125 MHz).
Each input has two independently programmable thresholds for determining
the status of the input ("High" or "Low"). The setting range for these threshold
values is +0 V to +10 V.
Note
The ES5340.1-S (Slave Board) does not have any analog inputs!
