Pneumercator 4-Relay Output/4-Contact Closure Input Expansion Card - (SKU: 900428-1) is an OEM add-on card that provides four programmable dry contact inputs and four relay outputs to expand system flexibility within Pneumercator TMS3000, TMS4000, and compatible consoles. This board enables user-defined event-driven automation and monitoring for advanced tank gauging and alarm system applications.

Flexible Dry Contact Integration: Each input is optically isolated, supporting standard dry contact wiring from external devices such as float switches, alarms, or sensors. It enables system designers and operators to trigger actions or record external events directly through the monitoring system’s user interface.

Programmable Relay Outputs: The card delivers four individually controlled relay outputs (Form C, rated 10A @ 120/240VAC) for activating connected loads, annunciators, or remote alarms. All inputs and outputs are fully user-programmable for activation based on system alerts, setpoints, and tank data.

Seamless OEM Compatibility: Designed for plug-and-play installation, the 900428-1 card locks securely into dedicated expansion slots. No special tools or configuration required, and UL/CSA listing ensures code compliance for safety-critical fuel system installations.

Applications: Extends tank farm, fuel depot, and industrial monitoring sites with additional contact closure inputs for sensor integration and powerful relay outputs for alarm and equipment control. Ideal for upgrades, retrofits, or expanding system automation requirements.

Specifications: Manufacturer – Pneumercator; Part Number – 900428-1; Inputs – 4 optically-isolated dry contact (programmable); Outputs – 4 relay (Form C, programmable, 10A rated); Compatibility – TMS3000, TMS4000, TMS4000W; Standards – UL/CSA listed.

Summary: The Pneumercator 4-Relay Output/4-Contact Closure Input Expansion Card (SKU: 900428-1) provides industry-standard, reliable I/O expansion for advanced monitoring and automation of critical tank and fuel management systems.
