Core parameters and structural characteristics
1. Key electrical and physical parameters
Conductor specifications
Multi strand tinned copper wire, wire diameter 0.5-1.0mm ² (suitable for 24V DC signal transmission and low-power power supply), current carrying capacity ≤ 5A
Contact configuration
Prefabricated plug-in terminal contacts, made of silver based alloy material (anti welding, wear-resistant), with a standard spacing of 3.5mm/5.0mm between contacts, supporting spring terminal connections
Insulation and shielding
The insulation layer is made of flame-retardant PVC (temperature resistance level -40 ℃ to 105 ℃), and the outer layer is wrapped with tin plated copper mesh shielding (shielding rate ≥ 90%), effectively resisting EMC interference
Cable length
Standard length 0.5m/1.0m/2.0m (customizable), bending radius ≥ 6 times the outer diameter of the cable, suitable for compact wiring requirements inside the cabinet
Protective performance
The contact area has an IP20 protection level and is suitable for a dry and dust-free environment inside the control cabinet; Overall compliant with UL 94 V-0 flame retardant standard
2. Highlights of structural design
Integrated prefabricated structure: The contacts and cables are crimped and formed without the need for on-site crimping tools, increasing wiring efficiency by more than 60% while avoiding signal drift caused by loose wires.
Polarity error prevention design: The contact adopts a concave convex alignment structure, which can only be inserted into the terminal according to the correct polarity to prevent module burnout caused by reverse connection (such as reverse connection of the positive and negative poles of the power supply).
Clear identification: The cable surface is printed with the model, wire sequence number, and direction identification, which corresponds to the terminal unit number to reduce the risk of wiring errors.
Adaptation scenarios and connection specifications
1. Core adaptation equipment
Adapt to device types
Specific model and connection purpose
I/O module
ABB S500 series analog/digital modules (such as AI810 analog input module, DO810 digital output module), used for signal transmission
Terminal unit
TU516 spring terminal unit (1SAP212000R0001), realizing the intermediate connection between the module and external equipment
Control module
I/O cards compatible with ABB Bailey DCS system, used for power supply and control signal interaction
External devices
Circuit breaker auxiliary contacts, sensors (such as RTD temperature sensors), relay coils, etc., transmit switch status or analog data
2. Connection and installation specifications
Wiring process:
Confirm that the power supply of the module and terminal unit is disconnected, and distinguish the signal line (such as DI/DO/AI/AO) from the power line according to the cable identification;
Insert one end of the cable contact along the terminal unit guide slot (lock it when you hear a "click" sound), and insert the other end into the corresponding interface of the module;
Pull the cable to verify the firmness of the connection, ensure that there is no looseness, and restore the power supply. Confirm that the signal transmission is normal through the module indicator light.
Wiring requirements:
The distance between strong electrical cables (such as power cables) should be ≥ 30cm, and vertical crossing should be used at intersections; Single ended grounding of the shielding layer (preferably on the terminal unit side), with a grounding resistance of ≤ 1 Ω, to avoid the formation of grounding circulation.
Collaborative application with SPCJ4D34-AA:
When the SPCJ4D34-AA industrial Ethernet I/O module needs to expand terminal interfaces, it can be connected to the TU516 terminal unit through TK516 to achieve remote I/O signal relay access, especially suitable for scenarios where the distance between the module and external devices exceeds 0.5m, ensuring stable transmission of 8-channel DI/4-channel DO signals.
