NewTrend · intermediate control relay
Product overview
NewTrend R8-316 is a DIN-rail intermediate relay for switching control-circuit loads and multiplying available contacts. It provides 3 spdt rated 16A AC-1, with a maximum changeover time of 40ms and red LED output indication. Choose a separate AC/DC 12V, AC/DC 24V or AC 230V version. All three output changeover contacts use the exact-model terminal arrangement shown in the catalogue. The 18mm DIN-rail body supports compact panel installation.

Operation
- Apply the selected nominal supply to the exact terminals shown for that voltage version. The supply choices are separate versions, not a continuous adjustable-voltage range.
- The red LED indicates output state. The changeover contacts switch the connected control circuits when the relay is operated.
- Use the R8-316 diagrams for the three changeover contacts. Do not apply the A3 arrangement used by other R8 models.
Typical applications
- Contact multiplication in automation and control panels
- Switching control-circuit loads within the stated AC-1 contact rating
- Interface and auxiliary switching in compact DIN-rail installations

Original wiring for every model and voltage version, with dimensions
The product photographs show the AC/DC 12V version; printed voltage markings are retained. Select the supply version before wiring. The R8-316 uses A1-A2 and has no A3 dual-input arrangement. Its three contacts do not change the stated 250VAC/24VDC switching-voltage limit. Installation and wiring must be performed by qualified electricians.
