Smart Relay 4 – Smart GPIO Converter

The Smart Relay 4 is a perfect tool for converting sustained network contact closures to pulses or applying logic/timing functions. The Smart Relay 4 provides four independent DPDT relay outputs and eight optically isolated wet or dry inputs. User programmable logic and pulse stretching (delays) may be set from 50 ms to 99 hours, 59 minute and 59.99 seconds.

Description

Most programming can be accomplished with simple dipswitch settings, while advanced configuration is performed thought the serial port using a non-dedicated PC with Windows HyperTerminal. Screw terminals are provided for all connections. The Smart Relay 4 is supplied in an aluminum chassis. The unit may be set on a desktop, mounted on a wall, up to two units mounted on the RM-3 (1-RU).
NOTE: The DIN brackets allow the mounting of all Flex Chassis products. Contact the factory for pricing.
