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.
The Smart Relay 4 G2 provides four independent GPIO interfaces in one box, each equipped with two optically isolated inputs (wet or dry) and a 2PDT relay output.

Connection through an RS-232, RS-422 or RS-485 serial port with baud rates up to 38400 the SRC-16 can notify your PC software program that any of 16 optically isolated inputs has been opened or closed and allows your software to control sixteen SPDT, 1-amp relays.
The SRC-16 Plus is connected through an RS-232 or RS-422/485 serial port and can notify your PC software program of GPI/trigger inputs on 16 optically isolated inputs and allows your software to control any of the 16 SPDT, 1-amp relay outputs.

The SRC-4 interfaces four optically isolated GPI/trigger inputs and four SPDT relay outputs to a RS-232 serial port. The SRC-4 can notify a users PC software program that any of four optically isolated trigger inputs have been opened or closed and allows the users software to control four SPDT relay outputs. Communication with the SRC-4 is accomplished via short “burst” type ASCII commands from the users PC.
