Introduction
This document provides safety information, installation instructions, and specifications for the Keithley Model SRA-01 8-Chan-
nel solid-state I/O-module accessory board.
Description
The SRA-01 interfaces full-size, industry-standard digital I/O modules to a variety of digital I/O and combined analog/digital
I/0 boards. The digital I/O modules allow the board to sense AC and DC signals and switch AC and DC loads. The SRA-01 is
compatible with the following Keithley boards:
•
Digital I/O boards: KPCI-3160, KPCI-PIO96, PIO-96J, PIO-12/24, KPCI-PIO24, and KPCMCIA-PIO24
• Combined analog/digital I/0 boards: KPCI-3107/3108, DAS-1600/1200, and DASCON-1
Four types of modules can be used with the SRA-01: DC input, DC output, AC input, and AC output. Sockets K1 through K4
of the SRA-01 accommodate any combination of input or output modules. (A switch for each socket configures it as either an
input-module socket or as an output-module socket.) Sockets K5 through K8 accommodate four output modules, only. If you
connect a PIO-12/24 to the SRA-01, socket K9 accommodates an additional input module to isolate an interrupt signal source
from the PIO-12/24 interrupt input.
LEDs monitor all module activity.
Safety summary
WARNING
This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions
required to avoid possible injury. Read the operating and safety information carefully before using the product.
Users of this product must be protected from electric shock at all times. The responsible body must ensure that users are pre-
vented access and/or insulated from every connection point.
Do not connect switching cards directly to unlimited power circuits. When connecting sources to switching cards, install pro-
tective devices to limit fault current and voltage to the card.
Installation
WARNING
CAUTION
Read and follow the "Safety Precautions" discussed at the end of this manual.
Users of this product must be protected from electric shock at all times. The responsible
body must ensure that users are prevented access and/or insulated from every connection
point. In some cases, connections must be exposed to potential human contact. Product
users in these circumstances must be trained to protect themselves from the risk of elec-
tric shock. If the circuit is capable of operating at or above 1000 volts, no conductive part
of the circuit may be exposed.
Ensure that the computer power is turned OFF before installing the SRA-01. Connect-
ing the SRA-01 to the computer while the power is ON can damage your computer, the
accessory, or both.
