±0.1% analog input accuracy and 10 kHz sampling rate ensure precise measurement of critical parameters, from subtle temperature changes to rapid pressure fluctuations.

Robust Isolation

2500 VAC isolation prevents electrical noise and ground loops, ensuring signal integrity in noisy industrial environments with motors, drives, and high-voltage equipment.

Flexible Control Logic

Digital outputs with Form C relays enable automated responses (e.g., valve actuation, alarm triggers) based on preconfigured thresholds, enhancing operational safety.

Seamless Backplane Integration

Connects to the 3500 system backplane for real-time data sharing with monitoring modules and communication gateways, enabling centralized control and SCADA/DCS integration.

Function

The primary function of the 3500/15E 164949-01 is to expand the 3500 system’s ability to monitor and control industrial processes. It collects analog signals from sensors (e.g., pressure transducers, RTDs) and digital signals from limit switches, processes them to filter noise, and converts them into actionable data. The module transmits control signals via analog outputs and relays to actuators, valves, or alarms, enabling automated adjustments based on machinery health or process conditions. By integrating I/O data with vibration and position monitoring, it supports holistic fault detection and preventive maintenance.

Use

In industrial settings, the module is installed in the 3500 system rack, connecting to external sensors and control devices. It interfaces with pressure probes on pumps, temperature sensors on bearings, and limit switches on conveyors, feeding data to the 3500 system for analysis. Its outputs control valves, dampers, or alarms, allowing operators to automate responses to critical conditions. Configured via 3500 software, it adapts to specific applications, from monitoring turbine oil pressure to triggering shutdowns during abnormal flow rates.

Application Fields
