Description

The ADR2200 relay I/O interface allows control of 8 relay contact outputs, 4 contact or TTL inputs, and one event counter via an RS232 or RS485 link. The ADR2200 can effectively convert a standard PC to a powerful PLC (programmable logic controller). This low-cost serial relay contact interface is easy to use with Visual Basic, Basic, C, Labview, Testpoint, or other high level languages that allow access to a serial port. The ADR2000 series of data acquisition interfaces are daisy chainable up to ten units. All ADR2000 series boards contain RS232 to RS485 converters.
