ISM-TRM-ISO-OUT 24 Line, Isolated Output Signal Conditioning Module Features • Small form factor industrial I/O termination board • 24 optically isolated outputs • Each output is an Open-Collector Darlington driver that can sink 500 mA from a 5-30VDC external source • Custom configurations with optically isolated inputs and/or relays available for OEM-specific applications • 2500 volt isolation of the signals • Convenient and reliable, pluggable quick disconnect terminal block connectors for field wiring • Ribbon cabling directly compatible with WinSystems’ single board computers and individual I/O modules • +5V power supplied through the interface cable • Small 3.6 x 3.8 inches (90 x 96mm) size allows the module to be put in a stack or to standalone • Operates from -40°C to +85°C • RoHS compliant board Product Description WinSystems’ ISM-TRM-ISO-OUT provides 24 lines of optically isolated outputs to provide easy connection and signal conditioning from field wiring. The board is needed for applications requiring signal isolation between an embedded computer and monitoring control points. Optical isolation creates a barrier which will eliminate common mode voltage, prevents ground loops plus provides safety for industrial applications. To interface with field wiring, the boards use a 3.5mm pitch pluggable connector to insure a reliable connection with easy removal and insertion. A minimum of three micro-inches of gold plating is on all the connector mating surfaces. The connectors are located on three edges of the board and are grouped for 8-lines per edge. There are two signal lines associated for each bit since isolation is provided from the host interface. ISM-TRM-ISO-OUT Block Diagram These boards will work with small form factor embedded PC and I/O modules that use the WinSystems’ WS16C48compatible digital I/O controller connector pinout. It will work with other manufacturers’ products as well. All these boards have the same physical dimensions and mounting holes as the 3.6 x 3.8 inches (90 x 96mm) Industry Standard Module (ISM). This allows ease of mechanical layout and packaging while offering excellent configuration flexibility. WinSystems | 715 Stadium Drive, Arlington, TX 76011 USA | Tel 817-274-7553 | Info@WinSys

Connectors Field wiring I/O controller Isolated power Isolated Output - Each output line is optically isolated from the digital I/O controller interface circuit. The isolation voltage rating between the input and output of the photo coupler device exceeds 2500V. Each output has a NPN Darlington transistor pair with an integral clamp diode for switching inductive loads and transient suppression. Each output line is capable of sinking 500 mA of current required by most relays. The collector-emitter voltage can withstand up to 30 volts. Isolated Power - There is a separate 2-pin pluggable...
