✅ core functionality

High density transistor source type output single slot realizes 32 channels of 24VDC output, and PLC logic instructions are converted into on-site positive pole output; Load connection method: Module output point → load → 0V; only supports PNP source type, cannot directly drive NPN negative load.

4-channel independent isolation group (core advantage) 4 groups each have independent common power supply and are isolated between groups; It can connect multiple different 24V power supplies, and a short circuit fault in one group will not burn out the other channels. It has strong anti-interference and fault tolerance capabilities, suitable for mixed use scenarios of multiple different power supply circuits on site.

The high-speed switch outputs a 0.5ms high-speed response, suitable for loads that require high-frequency switching; Transistors have no mechanical contacts and have a much longer lifespan than relay output modules, making them suitable for frequent operating conditions.

The inductive load protection is equipped with an RC absorption circuit. For electromagnetic valves and coil inductive loads, it is recommended to use an external parallel freewheeling diode to suppress the reverse electromotive force protection module; Turn off the leakage current very little to avoid the small indicator light from accidentally turning on.

Local and remote I/O compatibility can be installed on local baseboards, expansion baseboards, and remote I/O baseboards; Occupy 32% Q output register bits; LogicMaster90/Proficy ME software configuration; All CPU stop state outputs are forced to shut down for safety protection.

🛠 Typical application cases

Case 1: Large scale assembly line sorting equipment (most commonly used)

Cooperate with IC693MDL655 (32DI), one card DI+one card DO to achieve 32 inputs and 32 outputs; Drive a large number of cylinder solenoid valves, sorting baffles, workstation indicator lights, and small intermediate relays; Multiple locations, saving cabinet slots; 4 groups are isolated to separate the power supply for the alarm circuit, execution circuit, and indicator light circuit, reducing fault chain.

Case 2: Packaging/Filling Automation Production Line

Control multi station solenoid valves, silo gates, conveyor start stop relays, and alarm buzzers; High frequency action, 0.5ms high-speed response adapted for fast workstation switching; Multiple groups are isolated, and the power solenoid valve and signal indicator light are powered separately to avoid electromagnetic valve interference with the signal circuit.

Case 3: Machine tools and assembly tooling equipment

Fixture solenoid valve, workstation actuator, indicator light output; There are multiple device locations, so use 753 to reduce the number of modules; Replacement of old imported equipment spare parts, and direct replacement of damaged DO cards for a large number of old 90-30 equipment repairs.

Case 4: Material conveying, warehousing and transplanting equipment

Drive transplanting mechanism, blocking cylinder, photoelectric alarm light; Separate power supply for multiple circuits, utilizing four sets of isolation characteristics to reduce on-site ground loop interference.
