Data acquisition (DAQ) boards

ISA data acquisition (DAQ) boards are available with analog output or digital I/O. Not recommended for new applications. Features include analog I/O, digital I/O, and counting/timer functions. Available with concurrent operation, high current output and COMM port interface.

The ISA Data acquisition (DAQ) boards includes the following products:

• CIO-DAC16
• CIO-DDA06
• CIO-DIO24
• CIO-DIO24/24H
• CIO-DIO96
• CIO-DUAL-AC5
• CIO-PDISO8
• CIO-RELAY32

Features of each product in the ISA line:

The CIO-DAC16 has 16 channels of 12-bit analog output (one D/A per channel). Analog outputs are dual-DAC AD7273s (two analog outputs per chip), with each output buffered by an OP07. The CIO-DAC16 is compatible with MetraByte’s DDA-06 but lacks digital outputs. Software designed for the DDA-06 will operate the analog outputs.

The CIO-DDA06 has 6 12-bit analog output channels and 24 digital I/O lines. Analog outputs are dual-DAC AD7273s (two analog outputs per chip), with each output buffered by an OP07. Digital I/O is done with an 82C55 chip. The CIO-DDA06 is 100% compatible with MetraByte’s DDA-06.

The CIO-DIO24 has 24 digital I/O connections and an 82C55 . parallel interface chip Each 82C55 chip drives 24 CMOS/TTL compatible digital I/O pins. The 82C55 is configured as two 8-bit ports and two 4-bit ports. Each port is programmable for input or output.

CIO-DIO24H là bo mạch thu thập dữ liệu I / O kỹ thuật số 24 dòng TTL ổ đĩa cao. The control register sets the direction of the I/O ports to be the same as the 82C55 in mode 0 (see datasheet 82C55). The outputs are capable of 15 mA source and 64 mA sink.

The CIO-DIO96 is a 96-bit digital I/O board with four 82C55 parallel interface chips. The board provides 96-bit in a 24-bit group based on the 82C55 specification. Each 82C55 chip drives 24 CMOS/TTL compatible digital I/O pins. Each 24-bit group is divided into three eight-bit ports, or two 8-bit ports and two 4-bit ports. Each port is programmable for input or output.

The CIO-DUAL-AC5 is a 48-bit digital I/O data acquisition board. The 48-bits of digital I/O are organized into two 24-bit groups based on 82C55 mode 0 emulation (no swipe I/O or bidirectional I/O bits). Each 24-bit group is divided into three eight-bit ports – Port A, Port B, and Port C. PORTC can be divided into two four-bit ports – Port C-HI and Port C-LO. Each port can be individually programmed as input or output.

The CIO-PDISO8 is an eight channel-isolated high voltage digital input and eight relay output interface board. You can use the CIO-PDISO8 for control and sensing applications where high voltages need to be sensed or controlled.

CIO-RELAY16 is a 16-channel relay interface board for ISA bus computers. The board provides 16 Form-C relays (SPDT). The CIO-RELAY08 data acquisition board is the same as the RELAY16 board except that only eight relays are installed. CIO-RELAY 32 is two CIO-RELAY 16 on one board while CIO-RELAY24 is CIO-RELAY32 with only 24 relays installed.
