Engineers will appreciate the high-current output capability of the GALVPLNTH. This module delivers 0.75A per channel for driving solenoids and contactors directly. Consequently, users can eliminate external interposing relays in many applications.

Furthermore, the integrated protection circuits safeguard both the module and connected devices. Each output channel includes short-circuit protection with automatic reset. The GALVPLNTH also provides overload protection to prevent damage during fault conditions.

Output Configuration and Isolation

The GALVPLNTH features 16 solid-state transistor outputs for reliable switching. These outputs switch on and off in just 1 millisecond for precise control. The module provides 1.5 kilovolts of isolation between output circuits and the backplane bus.

This isolation protects the system controller from field wiring faults. Engineers can rely on this feature for long-term reliability in electrically noisy environments. The module also includes LED indicators for each output channel.

System Integration and Installation

You can install this output module in any INFI 90 rack system. The GALVPLNTH communicates with the controller through the Module Bus. A removable screw terminal block simplifies field wiring connections.

The module consumes 3.5 watts from the backplane power supply. This moderate power draw allows dense module configurations per rack. For reference, other Bailey INFI 90 digital output modules share this same form factor and installation method.

Diagnostics and Operational Reliability

The GALVPLNTH includes comprehensive diagnostic features for system monitoring. Status LEDs indicate power, communication, and output status for each channel. The module performs continuous self-checks to detect short circuits and overload conditions. These diagnostics simplify troubleshooting and ensure reliable actuator control.
