FAQ

Q1: EC20-0016ERN vs EC20-1616ERA?
A: ERN is output-only (16 relays, no inputs), bus-powered from CPU. ERA is active with 16 inputs + 16 relay outputs and its own 220VAC PSU.
Q2: Need external power supply?
A: No. Powered entirely through the EC20 bus connector from the CPU. Relay contacts can switch external AC/DC loads up to 2 A independently.
Q3: Guaranteed original?
A: Yes. 100% genuine Emerson, individually tested, 12-month warranty, BOM traceable.
