Description
The ET-7261/PET-7261 provides 11 form A electromechanical relays. It features optical isolation for 3000 VDC of transient overvoltage protection and doesn’t have channel-to-channel isolation. The power-on value and safe value of relay are programmable. It can safely be used in applications where hazardous voltages are present.
