4-channel 2 A output slice for ET 200SP
The 6ES7132-6BD21-0BA0 is a SIMATIC ET 200SP digital output module delivering four channels at 24 V DC, each rated for 2 A continuous — enough to drive small contactors, solenoid valves, or indicator banks directly without an interposing relay. It is a source (PNP, sourcing) output, meaning the load connects between the output terminal and ground (M); the module switches the positive side. This matches the wiring convention used in most North American and European control panels where the common is 0 V. The module fits base units of type A0 and carries color code CC02 for visual slot identification on the ET 200SP rail — a small but time-saving detail during commissioning when you are tracing a 24 V feed across a crowded backplane.
On-board diagnostics and substitution logic
Built-in module diagnostics cover short circuits to L+ and to M, plus wire break detection on each channel. When a fault is detected, the module can output a substitute value (configured in the hardware config) rather than dropping to zero — useful on lines where a safe-state hold is preferred over a hard stop. Supply voltage monitoring is also included; if the 24 V feed to the module drops below the operating threshold, the diagnostics flag it before the outputs begin to chatter.
Active lifecycle and compliance
RoHS compliance is confirmed effective 16 July 2024. The module also carries a REACH Article 33 duty-to-inform declaration for lead (CAS 7439-92-1) above 0.1% w/w — this is a standard disclosure for electronic components with tin-lead solder terminations and does not affect normal handling or installation.
