    DIN-rail RS485 digital I/O expansion for SysTec IT-series terminals.

    The SysTec REL485 (ordering code 50REL328-E) is a DIN-rail RS485 digital input/output expansion module for SysTec IT-series weighing terminals. It switches solenoid valves, pilot lamps, and motor control centers, and reads push buttons, switches, and sensors through optoisolated inputs.SysTec REL485 RS485 relay output module

    02 / 04Key features

    8 inputs, 8 relay outputs, expandable I/O bus.

    Each REL485 adds eight optoisolated inputs and eight relay outputs to a SysTec IT-series terminal over RS485, and up to eight modules share one bus.

    • 8 optoisolated 24 V DC inputs
    • 8 galvanically isolated relay outputs (24 V DC / 2 A and 250 V AC / 2 A, normally open)
    • Up to 8 modules per RS485 bus (64 inputs + 64 outputs), addressed via rotary switch
    • ~3 ms signal transmission, up to 1,000 m cable
    • Per-channel input/output LEDs plus a status LED
    • DIN-rail snap-on mounting, IP20
    • ETL listed (UL 61010-1/-2-201, CSA C22.2), FCC Part 15
