• Physical Interface: Two 24-pin male connectors

Key Functional Features

• Dual-Mode Voltage Operation: Each of the four output groups can be independently configured for TTL mode (5VDC for low-power logic circuits) or 12/24VDC mode (for driving higher-power field devices like solenoids and lamps) by connecting the appropriate external power supply to that group’s common terminal. This flexibility allows one module to serve mixed-voltage applications.

• High-Density Packaging: Integrates 32 output points into a single PLC slot, conserving valuable space within the control cabinet and reducing the need for additional baseplates and power supplies.

• Negative Logic (Sinking) Design: The module acts as a switch to ground (common). The load’s positive terminal connects to the external power supply positive, and the load’s negative terminal connects to the module’s output point. When the output is ON, the circuit is completed to the common/ground.

• Comprehensive Output Protection and Indication: Features include built-in pull-up resistors for TTL logic, optocoupler isolation between the field and logic sides, and individual LED indicators for each of the 32 points to provide immediate visual status of the ON/OFF state.

• Fast and Robust Performance: Delivers a switching response time of 0.5 milliseconds or less for both ON and OFF operations. It can handle inrush currents up to 4.6 A, making it suitable for loads with initial surge requirements.

Application Scenarios

• Manufacturing Automation: Controls solenoid valves and pneumatic actuators on assembly lines, and drives pilot lights and annunciators for machine status indication.

• Process Industries: Manages relay coils, small contactors, and alarm indicators in chemical, petrochemical, and power generation facilities.

• Mixed-Voltage Control Panels: In a single panel, one group can drive sensitive TTL inputs on an adjacent display controller, while another group simultaneously controls 24VDC indicator lamps for an operator station. This is enabled by the independent per-group voltage mode configuration.

• Water and Wastewater Treatment: Used for controlling small pumps, valve actuators, and status indicators in treatment plants where reliable sinking output logic is required.
