Key Features

1. High-Density I/O: 32 outputs reduce rack space and cost per point.
2. Dual-Voltage Operation: Switchable TTL (5 VDC) and 12/24 VDC modes for flexible load control.
3. Negative Logic (Sinking): Active-low outputs compatible with common industrial NPN transistors and TTL devices.
4. Grouped Outputs: 4 isolated groups enable independent power distribution and fault containment.
5. Built-In Protection:
   • Short-Circuit Protection: Per-channel overcurrent protection.
   • Transient Suppression: Absorbs voltage spikes to protect circuitry.
6. Clear Status Monitoring: Individual LEDs display on/off status for quick troubleshooting.
7. Rugged Industrial Design: Withstands vibration, noise, and wide temperature ranges.
8. Seamless PLC Integration: Directly compatible with Series 90-30 PLC backplanes (5 or 10-slot).

Applications

• Factory Automation: Control of solenoid valves, contactors, relays, and small DC motors in assembly lines.
• Packaging Machinery: Actuators, sensors, and TTL-compatible logic devices.
• Material Handling: Conveyors, lift gates, and sorting mechanisms.
• Machine Tools: Coolant pumps, door interlocks, and auxiliary axes.
• Digital Control Systems: TTL-level signaling for communication modules and custom circuits.
• Legacy System Upgrades: Replacement for older 90-30 installations in process and discrete manufacturing.

Additional Notes

• The module requires external user-supplied power for loads (not powered by the PLC backplane).
• When the CPU stops, all outputs turn off (fail-safe behavior).
• For high-current loads (3–4 A), connect both common pins per group to ensure adequate current handling.
