ERP3504-0022 | EtherCAT P Box, 4-channel analog input, measuring bridge, full/half/quarter bridge, 24 bit, 10 ksps
The ERP3504-0022 EtherCAT P Box module was developed for evaluating measuring bridges in full, half, and quarter bridge configuration outside the control cabinet. It also supports the potentiometer, Pt1000 (RTD), and ±10 V measuring ranges. Like the EPP3504-0023, it is derived from the ELM3504 EtherCAT Terminal and also features a sampling rate of 10,000 sps, internal switchable supplementary resistors, and an integrated, parameterizable bridge supply. It even features the same technological features as the ELM3x0x Terminals, meaning all parameters can be set via EtherCAT using the CoE directory.
As an IP67 product, the ERP3504-0022 is designed for use close to the measurement location and protects against interference due to the metal housing.
