ACL-7125
8 Channel Relay Actuator & Isolated D/I Card
AC/DC Polarity Free Inputs !!


Description

The ACL-7125 provides 8 electro-mechanical SPDT relays and 8 opto-isolated digital inputs on a compact board.

The 8 electro-mechanical relay outputs are addressed as a single I/O byte. Four of the relays are Form C contacts (normally open and normally closed) and the remaining relays are normally open. A red LED indicates each relay's ON/OFF status for monitoring.

The 8 opto-isolated D/I channels are used for sensing digital inputs and provide 1,000 VDC for isolation. Can be configured as filtered AC or non-filtered AC by jumper settings.

Software

Two software tools support the ACL-7125.

An extensive library of functions is available that supports Microsoft C and Borland C/C++. Example programs are included to demonstrate how to write C programs for the ACL-7125.

The ACLS-DLL1 is a high performance Windows driver for digital I/O functions. It supplies a DLL that can be accessed from C, C++ and Visual Basic under the Windows 3.x environment.
