Introducing New eI/O Family Modules
Last month we introduced the eI/O architecture along with the first three eI/O modules. This month Sealevel announces four additional eI/O modules along with a Starter Kit to accelerate application development. These modules attach to the M200 baseboard and are controlled using digital I/O (e.g. Sealevel’s 8010 PCI card or 8203 USB to digital module) via a standard 50-pin ribbon cable connector. eI/O modules offer a cost-effective, modular alternative for I/O interface. For ease of implementation, Sealevel includes our SeaI/O drivers, utilities, and programming samples for Windows 98/ME/NT/2000/XP and Linux to aid in the development of reliable applications for eI/O Family products. We also include an OPC (or OLE for Process Control) driver which makes possible interoperability between automation and control applications, field systems, and business/office applications.

251 Opto-isolated Output Module, Sourcing
The M251 is an optically-isolated emitter-follower output module designed to control up to 24VDC devices. 500VDC isolation protects electronics from over-voltage damage. Connection to field wiring is accomplished via a 10-pin removable terminal block. Output state of each bit is displayed via on-board LEDs. Requires power supplied to field terminal block from external supply such as the optional PS101.

M270 Form C Relay Module, 2A
The M270 supplies 8 SPDT (Form C) dry contact relays that can be wired for normally-open or normally-closed operation at up to 2 amps. Field wiring is connected via two 12-pin removable terminal blocks. On-board LEDs indicate status of each relay (open/closed).

M271 Form C Relay Module, 8A
The M271 supplies 8 SPDT (Form C) dry contact relays that can be wired for normally-open or normally-closed operation at up to 8 amps. Field wiring is connected via two 12-pin removable terminal blocks. On-board LEDs indicate status of each relay (open/closed).

M280 Quad SSR Relay Module
The M280 module allows easy interface to one or two industry standard quad solid state relays (QSSR). The module can be configured as 8 inputs or 8 outputs and will accept AC and DC QSSRs. Input modules have built-in filtering to provide clean signals to the control system, and include transient protection circuitry. Field wiring connection is made via two 6-pin removable terminal blocks. Each I/O channel is protected by a 5A fuse which is socketed for easy replacement.
