Designed for high-accuracy voltage measurement within automated control topologies, the Beckhoff EL3602 is a dual-channel analog input terminal operating on the EtherCAT protocol. This high-precision module processes differential input signals across several user-configurable voltage ranges, providing reliable 24-bit resolution to the central control system. Optimized for applications requiring exceptional signal fidelity, it features electrical isolation and robust integrated filters to manage electrical noise in demanding industrial environments.

When replacing or integrating the EL3602, verify the TwinCAT software version and active EtherCAT XML Device Description (ESI) files. The EL3602 features dynamic configuration via CoE (CAN over EtherCAT) variables. Ensure that older systems designed for the calibrated alternative EL3602-0010 are checked, as scaling and calibration coefficients differ within the PLC program. When using multiple EL series modules, verify that the total E-bus current budget does not exceed the limits of the coupler or the power supply terminal; the EL3602 draws a sustained 190 mA from the E-bus.
The common-mode voltage (Ucm) must be kept strictly below 35 V relative to the internal E-bus ground to prevent measurement errors and potential damage. Ground loops are the primary source of drift in 24-bit applications. If measuring floating voltage sources, ensure the AGND terminal is linked to a clean, stable system reference to prevent the differential inputs from drifting into saturation. Additionally, allow a 15-minute thermal stabilization period after powering the cabinet to ensure the internal reference reaches equilibrium for 24-bit resolution stability.
Use twisted-pair shielded cabling for all analog signals. The shield should be terminated directly at the terminal (Terminal 3 or 7) for best high-frequency performance. In high-interference environments, utilize the TwinCAT system manager to activate the 50 Hz or 60 Hz notch filter inside the module's CoE registers. This significantly attenuates electrical line noise and maintains the module's ultra-low measurement error rating.
CRITICAL WARNING
Always isolate the power supply of the entire EtherCAT station before inserting or removing terminals. Failure to de-energize the E-bus could cause damage to the internal contact pins or result in system communication failures.
Align the terminal onto the 35 mm DIN rail (conforming to EN 60715) and slide it to lock into the adjoining module using the double slot and key connection.
Push the terminal forward until the orange locking slide snaps securely over the rail.
Insert a flathead screwdriver into the spring-actuated terminal openings to wire connections. Solid or stranded conductors (0.08 to 2.5 mm2, AWG 28-14) must be stripped exactly 8 to 9 mm.
Verify connection status using the integrated LEDs before applying full system logic power.
