IP20 protection class (for cabinet mounting), operating temperature range of -10 °C to +60 °C, and relative humidity ≤90% (non-condensing);
Powered by 24 V DC (19.2–28.8 V DC wide range), with galvanic isolation (500 V AC/1 min) between channels to resist electromagnetic interference (EMI) in industrial settings.
Communication Protocols: Supports dual-protocol functionality, including Profibus DP/V1 (slave/master mode) and Modbus RTU/TCP; compatible with ABB’s proprietary MasterBus 300 communication bus, enabling interoperability with ABB controllers (e.g., AC 800M, Advant Controller 450) and third-party devices.
Interface Configuration: 2 x Profibus DP ports (RS-485 physical layer, baud rate range 9.6 kbps ~ 12 Mbps), 1 x Ethernet port (RJ45, 10/100 Mbps, TCP/IP protocol stack) for Modbus TCP communication; 1 x MasterBus 300 interface (backplane connection) for integration with ABB control system chassis.
Data Transmission Capacity: Maximum Profibus DP node capacity of 124 slaves per port; Modbus TCP supports up to 64 concurrent client connections; data buffer size of 8 KB for input and 8 KB for output, ensuring efficient handling of high-volume real-time data.
Operating Environment: Operating temperature range -40°C ~ 70°C, storage temperature -40°C ~ 85°C; relative humidity 5% ~ 95% (non-condensing); vibration resistance 3 g (10 Hz ~ 500 Hz), shock resistance 25 g (11 ms, half-sine wave), compliant with IEC 61010-1 industrial safety standards.
Power Requirements: Input voltage 24 V DC (±10%), typical power consumption 6 W (full-load operation), standby power consumption ≤1.5 W; supports redundant power input to enhance system availability.
The technical characteristics of ABB 216AB61 ensure high stability and adaptability in discrete signal acquisition scenarios, with key parameters as follows:
Module Type: 16-channel isolated discrete input module, supporting 24V DC standard industrial signals. The logic level range is “0” (0–5V DC) and “1” (15–24V DC), compatible with photoelectric sensors, safety interlocks, pushbuttons, and other discrete devices, meeting multi-scenario signal acquisition needs.
Channel Isolation: Isolation voltage between channels is 250V AC (for 1 minute), and between channels and ground is 500V AC (for 1 minute). This effectively blocks cross-channel electromagnetic interference and prevents ABB 216AB61 from damage due to sensor circuit faults, ensuring signal accuracy.
Operating Environment: Temperature range of -40°C to +70°C, enabling stable operation in extreme environments such as outdoor substations and high-temperature workshops. Electromagnetic interference (EMI) resistance complies with the IEC 61000-6-2 industrial standard, unaffected by interference from high-power motors or transformers.
Power Supply & Consumption: Supports 24V DC power supply (with ±10% voltage fluctuation tolerance) and has a maximum power consumption of only 3.2W. It can be directly connected to the standard power circuit of PLC systems without additional power modules, reducing system deployment costs.
Response Time: Signal response time ≤ 1ms, quickly capturing sensor state changes (e.g., missing materials on conveyors, door switch actions). This ensures the PLC controller triggers linked controls (e.g., emergency shutdowns, alarm outputs) promptly to avoid production accidents.
Protection Rating: The module itself has an IP20 protection rating. It is recommended to install it in control cabinets with IP54 or higher protection to prevent dust and moisture from damaging the internal circuits of ABB 216AB61 and extend its service life.
