BECKHOFF 倍福 EL3112
EL3112 | 2-channel analog input terminals 0…20 mA, differential input, 16 bit
The EL3112 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitised to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal have differential inputs and possess a common, internal ground potential. The EL3112 combines two channels in one housing. Overload condition is detected, and the terminal status is relayed to the controller via the E-bus. The EtherCAT Terminal indicates its signal state by means of light emitting diodes. The error LEDs indicate an overload condition.
