“ The change-over relays have a short responding time. Transorb diodes and EMI filters protect the optoisolated inputs against high-frequency signals. The input voltage is 12 - 24V (DC). A 5 V version is available on request. A watchdog as downward counter resets the digital outputs after the reload value has run down. Time intervals can be programmed from 20 ms to 5s in 20 ms steps. ”
Relay board with 8 or 16 electromechanical relays 24 V with change-over contacts. 4 versions are available: whether with 16 or 8 relays and 8 digital inputs or with only 16 or 8 relays. Each relay can be used as change-over, closing and opening contact. Switching voltage up to 60VDC or 48AC can be connected. The maximal switching current is 1 A by maximal rupturing capacity of 62,5 VA, 30 W. The mechanical life is about 5 x 106 operations and the electrical life is about 1 x 105 operations. Several drivers like Linux (real-time), 32-bit drivers for Windows 7/Vista/XP/2000 (real-time) or signed 64-bit drivers for Windows 7/XP are delivered on a CD-ROM with the board.
