Safety Relay G7SA Slim Safety Relays Conforming to EN Standards The forcibly guided contact in the G7SA assures safe operation (EN50205 Class A, approved by VDE.) Ideal for use in safety circuits in press machinery, machine tools, and other production machinery. Four-pole and six-pole Relays are available. The Relays terminal arrangement simplifies PWB pattern design. Reinforced insulation between inputs and outputs. Reinforced insulation between some poles. VDE RC X UL, CSA approval. CE marking. Note: Be sure to refer to the Precautions on page 131.

The rated current and coil resistance are measured at a coil temperature of 23C with tolerances of 15%. 2. Performance characteristics are based on a coil temperature of 23C. 3. The value given for the maximum voltage is for voltages applied instantaneously to the Relay coil (at an ambient temperature of 23C) and not continuously.
