Industrologic announces the release of their RS51-SPR-RELAY, an RS-232 Serial Relay.
The RS51-SPR-RELAY is an extremely low cost and super easy to use RS-232 serial controlled relay. It was designed not only to be inexpensive, but to be easy to use as well. By receiving a short sequence of normal alphanumeric characters, the RS51-SPR-RELAY can control either a single relay, or the individual relays on up to 16 addressable RS51-SPR boards.
A female DB9 connector on the RS51-SPR board matches the pinout of the serial port of an IBM PC compatible computer and can be connected to it with a common DB9 pin-to-pin male-to-female cable. An additional male DB9 connector matches the pinout on the computer and provides a method of "chaining" multiple boards with the same cable. Up to 16 boards can be chained through these connectors and can be optionally powered from the power supply connected to the first board in the chain.
The on-board relay has 10 amp Form "C" contacts and convenient screw terminal block connections. The RS51-SPR-RELAY can be powered by its wall-block power supply or by connection to a screw terminal block.
The RS51-SPR-RELAY is shipped with all the items needed to quickly and immediately connect it to a PC compatible computer and begin operation: A wall-block power supply, an RS-232 cable, and an easy to use Reference Manual.
Complete information about the RS51-SPR-RELAY, including the complete technical reference manual, is on their web site at www.industrologic.com.
