Introduction 1:
EJ3004

4-channel analog input module, 12-bit, -10 V ... +10 V, single-ended inputs

The EJ3004 analog input module processes signals in the range from -10 V to +10 V. The voltage is digitized to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device.

In the EJ3004 module the four single-ended inputs are implemented in 2-wire technology and share a common internal ground potential. LEDs are used to indicate the signal state.
