ABB SPCIS22 Control I/O Module

• I/O point configuration: Includes 16 digital inputs and 8 digital outputs. Inputs support dry/wet contact signals; outputs are relay-type (capacity 250V AC/5A, 30V DC/5A).​

• Input signal parameters: Digital input voltage range 24V DC±10%, response time ≤10ms, with optical isolation (isolation voltage 2.5kV).​

• Output signal parameters: Relay outputs support normally open/normally closed switching, operating time ≤10ms, release time ≤5ms.​

• Communication interface: Equipped with RS485 interface, supporting Modbus RTU protocol, data transmission rate configurable (9600-115200bps).​

• Operating environment: Operating temperature -20℃~60℃, relative humidity 5%-95% (non-condensing), protection class IP20 (suitable for cabinet installation).​

• Power requirement: 24V DC±10% power supply, power consumption ≤8W (no load), ≤15W (full load).​

• Dimensions: Width×height×depth approximately 45mm×170mm×120mm, standard DIN rail mounting, compact structure.​

• Certification standards: UL, CE certified, compliant with IEC 61131-2 industrial control equipment standards.​

• Highly integrated design: Integrates multi-channel I/O interfaces in a compact size, reducing cabinet space, suitable for small and medium-sized automation systems.​

• Reliable isolation protection: Inputs and outputs adopt optical isolation and relay isolation, with strong anti-electromagnetic interference ability, ensuring stable signal transmission.​

• Flexible expansion capability: Supports multi-module cascading, realizes I/O point expansion through communication interface, meeting system upgrade needs.​

• Convenient debugging and maintenance: Equipped with LED status indicators, displaying input/output status in real time for quick troubleshooting; supports online parameter configuration.​

• Wide compatibility: Compatible with mainstream PLC and SCADA systems, can be directly connected to industrial control networks, simplifying system integration.​

• Building automation: Used for signal collection and control of access control systems, lighting control, air conditioning units, realizing intelligent management of building equipment.​

• Small production lines: In small production lines such as food packaging and electronic assembly, collect sensor signals (e.g., photoelectric switches, proximity switches) and control solenoid valves, small motors and other actuators.​

• Municipal facility control: Adapt to auxiliary control loops of sewage treatment stations and pump stations, monitor liquid level and pressure switch signals, and control valve and pump start-stop.​

• Machine tool auxiliary control: Used for peripheral equipment control of CNC machine tools, such as switch control and status monitoring of cooling systems and lubrication systems.​

• Energy management terminals: In small distribution rooms and photovoltaic inverter auxiliary loops, collect circuit breaker status signals and control alarm devices.​

• During wiring, distinguish input and output loops; avoid high-voltage access to signal terminals to prevent module damage; it is recommended to install fuses in output loops.​

• The module should be installed away from strong electromagnetic sources (e.g., frequency converters, contactors); if unavoidable, use shielded cables and ensure good grounding.​

• Check whether the power supply voltage meets the requirements before first power-on to avoid overvoltage burning the internal circuit.​

• Before reuse after long-term storage or shutdown, check whether the module appearance is damaged and terminals are loose; power on only after confirmation.​

• Disconnect the power supply before replacing the module to avoid interface damage caused by hot swapping.
