        Features:

        • Drives larger loads directly; parallel switching for up to 1.5A; 10 μA residual current for high‑impedance loads.
        • 500V AC isolation test; protects CPU from field wiring faults; reduces ground loops.
        • 45 mm wide, 150 g; plug‑in I/O terminals; operates up to 55°C; compatible with all S7-200 CPUs.
        The 6ES7222-1BF22-0XA0 provides 8 digital output channels, each rated at 0.75A at 24V DC. This is significantly higher than the 0.5A outputs found on many compact PLCs. The higher current rating allows direct connection of small solenoids, relay coils, and indicator lights without external interposing relays. For loads requiring more than 0.75A, the module supports parallel switching of two outputs for uprating. By connecting two outputs in parallel to the same load (and switching them simultaneously), the available current doubles to 1.5A. This is useful for controlling small motors or larger contactor coils.

        The 6ES7222-1BF22-0XA0 uses optocouplers to provide electrical isolation between the S7-200 backplane bus and the output circuits. The isolation is tested at 500V AC. This isolation serves two critical purposes. First, it protects the CPU and backplane from voltage spikes originating on the field side – for example, from inductive kickback when a solenoid de‑energizes, or from a short circuit between a field cable and a power line. Second, it prevents ground loops when field devices are connected to different power supplies. The 8 outputs are isolated in two groups of 4 channels each (channels 0‑3 and channels 4‑7). Outputs within the same group share a common reference (typically the M terminal).

        The 6ES7222-1BF22-0XA0 is designed for the SIMATIC S7-200 platform, one of Siemens’ most successful small PLC families. The module measures just 45 mm wide, 80 mm high, and 62 mm deep, weighing only 150 g. This compact size allows it to fit into tight control cabinets alongside the CPU and other expansion modules. The module uses plug‑in I/O terminals (screw‑type, included with the module). The plug‑in design allows the terminal block to be removed from the module while leaving field wiring connected – useful when replacing a faulty module without rewiring.

        The 6ES7222-1BF22-0XA0 SIEMENS Digital Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

        Description
        The 6ES7222-1BF22-0XA0 is a digital output module for the SIMATIC S7-200 PLC system. It provides 8 digital outputs rated at 24V DC, 0.75A per channel. The outputs are opto‑isolated in groups of 4 channels. The module has a typical power loss of 2 W and draws 50 mA from the 5V backplane bus. 

        When using the 6ES7222-1BF22-0XA0, engineers can control up to 8 field devices such as solenoid valves, indicator lights, and small relays. The outputs have inductive shutdown voltage limitation to L+ (-48 V). The module has no short‑circuit protection – external fusing is required. Parallel switching of two outputs is permitted for uprating (increasing current). 

        The 6ES7222-1BF22-0XA0 has isolation tested at 500 V AC between channels and the backplane bus. Channels are isolated in groups of 4 (channels 0‑3 and 4‑7). The output voltage for signal “1” is minimum 20 V at rated load. The residual current for signal “0” is maximum 10 μA. The module uses plug‑in I/O terminals for easy wiring and replacement. 

        For legacy S7-200 system expansions, the 6ES7222-1BF22-0XA0 provides a reliable 8‑point digital output solution. The module has no short‑circuit protection, so external fuses (e.g., 0.75A fast‑blow) must be installed on each output or group of outputs. 
        Alternative Names

        Technical notes
        The 6ES7222-1BF22-0XA0 has no short‑circuit protection. This means a direct short on an output will destroy the output transistor. Always install external fuses (0.75A fast‑blow) on each output or group of outputs. The module is designed for cost‑sensitive applications where external protection is provided.

        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.
        VIEW ALL FAQS
        Does 6ES7222-1BF22-0XA0 have short‑circuit protection?
        No. The 6ES7222-1BF22-0XA0 has no internal short‑circuit protection. You must install external fuses (e.g., 0.75A fast‑blow) on each output or group of outputs to prevent damage from overload or short circuits. This is a cost‑saving design choice.
        Can 6ES7222-1BF22-0XA0 be used for higher current loads?
        Yes. The module supports parallel switching of two outputs for uprating. For example, connect two outputs in parallel to a single load. Each output provides 0.75A, so two outputs in parallel can provide up to 1.5A. Ensure both outputs are switched together.
        What is the total current derating for 6ES7222-1BF22-0XA0?
        The module can supply 3A total per group (4 outputs) up to 40°C. At 55°C, the total current is also 3A for horizontal mounting. For vertical mounting, 3A up to 40°C, but no data above 55°C. Keep total load below 3A to prevent overheating.
        Does 6ES7222-1BF22-0XA0 protect against inductive kickback?
        Yes. The module limits inductive shutdown voltage to L+ (-48 V) , protecting the output transistors. However, for large relays or contactors, use an external flyback diode (for DC coils) or varistor (for AC coils) to further reduce voltage spikes and extend output life.
