  • Page 3: Introduction

    Introduction Overview The REL-32 provides 32 reed relays that can switch power, data, or other electronic signals for control applications. The outputs provide high quality, long life, low current (10 Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications. The relays are normally open and will close when energized.

  • Page 6: Card Setup

    The REL-32 contains several jumper straps for each port that must be set for proper operation. Address Selection The REL-32 occupies 4 consecutive I/O locations. The DIP-switch (SW1) is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports.

    Programming the REL-32 Sealevel’s SeaI/O software is provided to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. The software also includes driver functions for use in accessing the I/O as well as helpful samples and utilities.
  • Page 13 Programming the REL-32, Continued Digital I/O Interface The REL-32 provides four parallel input/output (I/O) ports. The ports are organized as ports 1, 2, 3, and 4. Output Ports (Reed Relay) Reed relays provide very high quality, long life, low current, dry contact switch closures. Reed relays are not suited for high current applications and can be destroyed by inductive load switching.
  • Page 14 Programming the REL-32, Continued Jumper Setup Options The common on each port may be tied to ground, 5, or 12 volts. Either side of each relay may then be tied to the common. The 3098 is shipped with all of the jumpers necessary for all possible configurations. The jumpers are parked on the B-side and are inactive until configured by the user.
