Features:
- Two independent relay channels each provide a normally open and a normally closed field contact.
- The output reaction to a CPU or master stop can use channel-specific substitute values or retain the last state.
- Electrical isolation separates both relay paths from each other, the module supply, and the station backplane.
Siemens 6ES7132-4HB12-0AB0 adds contact-based switching to a narrow ET 200S station position without tying the two loads to a common output circuit.
The terminal assignment keeps each common, normally open, and normally closed conductor identifiable from the field connection through the relay.
Green channel indicators show commanded output states, while circuit protection remains outside the module at the connected load wiring.
The Siemens 6ES7132-4HB12-0AB0 SIMATIC ET 200S 2-Channel Relay Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Following each relay from common to both contact states
- Channel 0 Common: Terminal 1 feeds the changeover contact whose normally open and normally closed paths leave on terminals 2 and 3.
- Channel 1 Common: Terminal 5 feeds the second changeover contact, with its switched paths on terminals 6 and 7.
- Independent Circuits: The two relay channels do not share a field common inside the electronic module.
- Terminal Module: The selected ET 200S terminal module carries these conductor positions to the field wiring.
Defining output behavior when cyclic control ends
- Module Choice: The station parameter selects either substitute values or preservation of the last valid output image.
- Channel 0 Value: A separate substitute bit determines the commanded state of the first relay.
- Channel 1 Value: The second relay has its own substitute bit and need not mirror channel 0.
- Return to Exchange: Normal process-image control resumes after the station returns to data exchange.
Keeping protection and switching duty with the field load
- External Fuse: Each load path uses the specified external fuse because the relay output is not internally short-circuit protected.
- Coil Suppression: Inductive loads require their suppression element in the field circuit because the module does not limit induced voltage.
- Contact Duty: Switching frequency is selected to match resistive, inductive, or lamp behavior rather than treated as one common rate.
- Voltage Class: When one channel is wired as SELV or PELV, the second channel remains within the same low-voltage class.
Load types explicitly covered for the relay outputs
- Solenoid Valves: The relay contacts can switch the documented solenoid-valve field circuits within their load limits.
- DC Contactors: Contactor coils are a stated load type when the coil circuit includes the required external suppression.
- Indicator Lamps: Lamp circuits are supported subject to the specified contact duty and switching rate.
- Mixed Commands: The two isolated channels allow different supported load types without sharing an internal field common.
