The safety relay SR series is a safety relay equipped with 3 NO (normally open) safety output contacts and 1 NC (normally closed) auxiliary output contact. It features single and dual-channel operation, manual or automatic reset.
Classic 22.5mm shell with a powerful versatility thanks to the appearance and size design.
Supporting multiple device inputs, such as emergency stop buttons, Safety Interlock Switches and safety light curtains.
Easy wiring and flexible installation
The circuit board is conformally coated to protect it from moisture, insulation, water, dust and loose parts;
