8 Channel Relay Actuator & Isolated D/I Card

AC/DC Polarity Free Inputs

Features

Hardware Description

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

Relay Outputs
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.
Relay type : Single-pole, double-throw (SPDT) Contact rating : 120V AC/0.5A or 30V DC/1A Breakdown voltage : 300V Peak AC/DC min. Relay on/off time : 5msec typical Relay current : +12V @ 33mA for each relay
Isolated Inputs
The 8 opto-isolated D/I channels are used for sensing digital inputs and provide 1,000V DC for isolation. Can be configured as filtered AC or non-filtered AC by jumper settings.
Opto-isolator : PC-814 Input channels : 8 Input signal : Non-polarized AC or DC Input voltage : 5~24V DC or AC 50~1,000Hz Input impedance : 1.2KW Isolation voltage : 1,000V DC channel-to-channel and channel-to-ground Response time : 20 µsec without AC filter, 2.2ms with AC filter
Power Consumption
+5V @ 200mA typical +12V @ 270mA max, all relays are energized

Two software tools are supported for the ACL-7125, they are:

Program Library & Examples
An extensive library of functions are available that support Microsoft C and Borland C/C++. Example programs are included to demonstrate how to write C programs for the ACL-7125.
Windows 3.x Driver (ACLS-DLL1)
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.
