Output Ranges and Isolation Characteristics

Unit weight is approximately 650 g with dimensions of 25 mm width, 290 mm height, and 210 mm depth. The SM 432 provides 8 isolated analog outputs with 13-bit resolution including sign. Voltage output ranges are 0 to 10 V, 1 to 5 V, and -10 V to +10 V; current output ranges are 0 to 20 mA, -20 mA to +20 mA, and 4 to 20 mA. Voltage outputs are short-circuit protected with a maximum short-circuit current of 30 mA. Current outputs present a maximum no-load voltage of 19 V. Conversion time is 420 us per channel, with 300 us in all ranges. Settling time is 0.1 ms for resistive load, 3.5 ms for capacitive load, and 0.5 ms for inductive load. Operational error limit over the full temperature range is +/-0.5% for voltage and +/-1% for current. Basic error limit at 25 deg C is +/-0.5% for both voltage and current. Potential separation exists between the channels and the backplane bus, and between the channels and load voltage L+, but not between individual channels. Isolation is tested at 2120 VDC between bus and L+/M. No diagnostics function is provided.

Frequently Asked Questions

Q: What is the weight and physical size of the 6ES7432-1HF00-0AB0?
A: Approximately 650 g, with dimensions of 25 mm width, 290 mm height, and 210 mm depth.

Q: Are the analog output channels isolated from each other?
A: No. Potential separation is provided between the channels and the backplane bus and between the channels and load voltage L+, but not between individual channels.

Q: What load impedance does the module support for current and voltage outputs?
A: Voltage outputs require a minimum of 1 kohm with capacitive load up to 1 uF. Current outputs support a maximum of 500 ohm, or 600 ohm when common-mode voltage is reduced below 1 V.

Field Installation Guidelines

Insert the module into the S7-400 rack and secure the mounting screws. Verify 24 VDC load voltage polarity before energizing; reverse polarity protection is provided. Route shielded analog output cables to a maximum of 200 m, with the shield grounded at one end. Confirm load impedance for voltage outputs is at least 1 kohm and for current outputs does not exceed 500 ohm. Verify conversion time and settling time against the loop response requirements before commissioning. Confirm isolation ratings against the field circuit potential before wiring.
