Each output supports a maximum current of 500 mA, subject to the applicable module and installation load constraints. The maximum specified switching response time is 450 us for both turn-on and turn-off transitions.\u003c\/p\u003e\n\u003cp\u003eThe module receives internal power and data through the TM3 bus expansion connector. Its output circuits provide 500 VAC isolation from the bus, while the individual output channels are not isolated from one another. External load wiring must therefore account for shared electrical references and the common supply arrangement.\u003c\/p\u003e\n\u003cp\u003eEach output has a dedicated green status LED.

Verify the drive input interface, signal common, and electrical ratings before connecting it. The module is not a power output stage for supplying a drive's motor.\u003c\/p\u003e\n\u003cp\u003eQ: Are the 16 output channels galvanically isolated from each other?\u003c\/p\u003e\n\u003cp\u003eA: No. The outputs are not isolated from one another. The specified 500 VAC isolation applies between the output circuits and the internal bus. External wiring must account for this distinction.\u003c\/p\u003e\n\u003cp\u003eQ: What are the mounting and operating-temperature requirements?\u003c\/p\u003e\n\u003cp\u003eA: The module supports TH35-7.5 or TH35-15 DIN rail mounting and panel mounting with a fixing kit. The specified operating range is -10 to 35 deg C for vertical installation and -10 to 55 deg C for horizontal installation.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMounting: Install the module on a compatible DIN rail or panel using the specified mounting arrangement. Maintain the required clearances and ventilation conditions of the controller assembly.\u003c\/li\u003e\n\u003cli\u003eBus connection: Align and engage the TM3 expansion connector with the adjacent controller or expansion module. Confirm mechanical engagement before applying power.\u003c\/li\u003e\n\u003cli\u003eField wiring: Connect the 24 VDC PNP outputs to compatible load inputs. Verify polarity, common reference, load current, and the electrical requirements of each connected device.\u003c\/li\u003e\n\u003cli\u003eTerminal tightening: Use the terminal manufacturer's specified tightening torque. Do not exceed the permitted conductor cross-section.\u003c\/li\u003e\n\u003cli\u003eCable routing: Separate output wiring from high-voltage power conductors and high-noise switching circuits where practical. Use appropriate shielding and grounding practices for the connected equipment.\u003c\/li\u003e\n\u003cli\u003eCable length: Keep unshielded output cables within the specified 30 m maximum.\u003c\/li\u003e\n\u003cli\u003eCommissioning: Verify channel assignments in the PLC program, inspect wiring for shorts and polarity errors, and test each output under controlled conditions. Confirm that the connected load remains within its electrical limits.\u003c\/li\u003e\n\u003cli\u003eEnvironmental conditions: Maintain the applicable temperature and humidity limits.
