VMEBUS INPUT/OUTPUT BOARDS VMEBUS INPUT/OUTPUT BOARDS AVME947x Industrial Digital I/O AVME9470/71: 80 channels, front/P2 access AVME9475: 40 channels, P2 access The AVME947x boards offer a variety of features to These I/O boards are extremely flexible to perform a variety of different I/O functions simultaneously on one card. simplify complex industrial control applications. They can perform up to four independent functions Operation at the same time to replace four other boards and Many I/O functions can be performed by these Debounce configuration implements a delay upon save three card cage slots. This is possible boards. Typical uses include change-of-state detection of a signal variation before rechecking because the I/O are divided into four individually monitoring. Vectored interrupts signal the host for a change in status. This allows the signal to configurable sections. Functions for each section computer upon a change in the digital input value settle and prevents mechanical switch noise and are field-selectable with a choice of up to five I/O or an 8-bit pattern match. Or, programmable electrical spikes from being read as a change in modes including Debounce, Interrupts, handshaking counter/timers may be used to generate pulse and the input value. The delay duration is controlled by or general purpose I/O. square wave outputs or count events. the programmable counter/timers. Each I/O section contains two 8-bit ports and one The handshaking configuration helps control data Features 4-bit port. This allows 64 general-purpose points capture for orderly communications. Choose AVME9470 and AVME9471 to be programmed individually as inputs and/or interlocked, strobed, three-wire, or pulsed mode. 64 points bidirectional I/O also usable as outputs on a bit-by-bit basis. The other 16 I/O 32 bidirectional I/O with 8 counter/timers points optionally serve as handshake lines for the 8-bit ports, counter/timers, or as bit I/O. Three 16 points bidirectional I/O also usable as selectable operating configurations are available 4 handshaking ports or 4 counter/timers for each section: debounce, handshake, and Programmable debounce delays on 64 I/O points standard bit I/O. Change-of-state monitor with vectored interrupts: - Change in signal from high to low - Change in signal from low to high - Matching an 8-bit word - Any value change Four handshaking modes Twelve 16-bit counter/timers TTL and CMOS compatible AVME9475 Same features as above except: 32 points bidirectional I/O also usable as 16 bidirectional I/O with 4 counter/timers 8 points bidirectional I/O also usable as 2 handshaking ports or 2 counter/timers 52 Acromag, Inc.
