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.
• Each 2PDT relay channel can be configured with two independent optically isolated inputs configurable for dry signals or wet signals (5-24 VDC, or 25-48 VDC via an external resistor.)
• LED status indicators are provided for each relay, input, and power.
• Fifteen logic functions include, sustained, toggle, set-reset (flip-flop), dual alternate action or failing/rising edge, along with additional Boolean logic functions.
• Independent pulse stretcher or time delays may be user programmed from 50ms to 99 hours, 59 minutes, 59.99 seconds.
• Timing and mode configuration from a non-dedicated PC using the USB-serial connection.
