Selection & installation notes
- P uses PA-N; E uses APAN. The official photograph shows APAN relays and illustrates the E alternative. Confirm the actual fitted relay.
- The input-current table does not explicitly state whether its electromagnetic figures are per channel. Confirm PLC output loading; do not calculate it solely from 110 mW coil power.
- Confirm jumper polarity and bridge-bar total-current capacity before commoning. Isolate power before wiring or replacing relays.
- Derate contact loads for inductive or inrush service. SSR alternatives have leakage and ON-state losses; confirm exact AC/DC applicability, especially EQZ202D.
- This page specifies torque and ambient limits different from generic family manuals; confirm the supplied product instructions.
Based on the official Chinese product page and selection charts ↗. Checked 2026-09-15. Confirm the current specification for the exact model when ordering.
