This manual introduces the basic connection and use method of eumax UM-SRM116-02 relay module, which is suitable for the output connection of Siemens signal template SM322, as well as the relay board of general PLC.
The UM‑SRM116‑02 relay module from EU‑MAX is designed for use with Siemens SM322 signal modules, generic PLC relay boards, and AC/DC 24 V circuits. The module contains 16 independent relay circuits, each rated for 1 A contact rating and can be driven by 0 V (common‑positive) or 24 V (common‑negative) control signals.
The manual details three wiring methods (XH connector, terminal block, IDC connector), provides dimensions (PCB 139 mm × 107 mm × 1.6 mm, overall module 141 mm × 123 mm × 45 mm), installation on TS‑32/35/15 rails, and safety precautions such as voltage limits and surface cleaning before use. This manual is written in Chinese.
