The neue relay board for PCI Express by Addi-Data is fitted with 8 or 16 electromechanic relays with change-over contacts. This enables every relay to be wired as a make, break or change-over contact. The board has been developed for a use in harsh industrial environment. The contacts are equipped for switching voltages up to 125 VDC/125 VAC. The maximum switching current is 2 A with a maximum switching capacity of 30 W. Up to 16 digital opto-isolated inputs are available. Transorb diodes and EMI filters protect the inputs, which are optically isolated up to 1000 V, from high-frequency interference radiation. Numerous drivers are delivered with the board.
