More Information

Overview Manuals Signal Types Timing Wiring Application
  • Sixteen voltage or current input channels
  • Thirteen-bit conversion resolution
  • Two-wire transmitter supply through 24 V L+

6ES7431-0HH00-0AB0 is a non-isolated SM 431 analog input module for Siemens SIMATIC S7-400 systems.

Its sixteen channels acquire configured voltage or current signals, including 4 to 20 mA transmitter loops, with 13-bit resolution.

Correct application depends on the selected range, field wiring, L+ transmitter load, common-mode limits, shielding, addresses, and conversion timing.

Availability, condition, price, and shipping time for 6ES7431-0HH00-0AB0 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can a buyer confirm that 6ES7431-0HH00-0AB0 suits the existing S7-400 signal application?
Review the complete module code, configured voltage or current ranges, field-transmitter types, common-mode conditions, addresses, wiring, and conversion-time requirements.
Which field devices should not be connected directly to 6ES7431-0HH00-0AB0?
Do not select it for direct thermocouple, RTD, or resistance-sensor measurement; those applications require a suitable module or signal-conditioning arrangement.
Are the channels of 6ES7431-0HH00-0AB0 isolated?
No. The channels are non-isolated from one another, the backplane bus, and L+.
Can 6ES7431-0HH00-0AB0 be used with existing two-wire transmitter loops?
Yes, when the L+ supply arrangement, total transmitter load, field wiring, shielding, range configuration, and common-mode conditions comply with the official module data.
What configuration must be restored when replacing 6ES7431-0HH00-0AB0?
Restore the module address, channel range assignments, integration settings, inactive-channel treatment, transmitter supply arrangement, and related PLC scaling and alarm logic.
Is the front connector automatically included with 6ES7431-0HH00-0AB0?
Do not assume it is included. The quotation should explicitly list the front connector and any coding, wiring, shielding, or replacement accessories required for the installed module.
What must be checked before replacing 6ES7431-0HH00-0AB0?
Confirm ranges, addresses, transmitter supply, shielding, front-connector wiring, common-mode voltage, conversion timing, and project configuration.
