Module installation and wiring specifications

Installation requirements: The module must be installed inside a metal shielded cabinet/enclosure, and the cabinet must be isolated from interfering components and cables through measures such as wiring separation and component space isolation; The signal cable needs to be shielded at both ends, and the shielding layer of the cable at the entrance of the cabinet needs to be laid flat and grounded. Open wiring is strictly prohibited.

Wiring method: using vertical front wiring, equipped with a press type terminal block, supporting screw/crimping/clamping connections; The module is labeled with clear analog I/O channels, reference outputs, and terminal assignments for power supply, and must be wired according to the identification.

Shielding and anti-interference:

Low frequency interference (such as 50Hz power frequency) is offset by a differential measurement system and high common mode suppression;

High frequency/pulse interference needs to be isolated through shielding measures, and the cable shielding layer needs to be grounded at both ends on site (outside the cabinet);

The interaction between all analog components and auxiliary power supplies needs to be considered as a whole to ensure system immunity.

Module operation and usage

Initialization and recognition: Module recognition and initialization are automatically completed by the upstream Cell Controller operating system, without the need for dip switch settings; If the+24V power supply is interrupted or the E-bus transmission is interrupted, the analog output will reset to 0V and the OUT-ENA LED status will change.

Data measurement and conversion:

The transmission of measurement and data to CAN nodes is cyclic, controlled by the operating system API, and AD conversion does not require a startup signal;

Data conversion formula: U=10V × AD/2 ^ 15 (voltage), I=20mA × AD/2 ^ 15 (current), AD is the output value of the analog channel;

Over range output: positive over range is+32752 (+9.995V), negative over range is -32768 (-10.000V); When the sensor fails, the corresponding channel reports+9.995V to the controller.

Sensor/actuator connection: Differentiated wiring according to sensor type is required, with the following core requirements:

Floating ground sensor: Connect IN+/AGND through a 2-core shielded wire, and bridge at least one measurement input (IN -) to AGND to avoid capacitive signal coupling and false measurement;

Active sensor with auxiliary power supply: Connected to IN+/IN – through a 2-core shielded wire, sharing the same power supply with the module. The AGND module remains open to ensure potential balance;

Sensors using internal reference voltage: Connect IN+/IN -/Ref/AGND through a 3/4 core shielded wire. Potential sensors need to bridge idle inputs to AGND to avoid reference voltage overload.

Analog output usage: The output is a floating ground ± 10V voltage, and each output is equipped with AGND (analog ground) and REF (common ground) terminals, which can compensate for ground bias (must meet | UREF |<2V); The SENSE line is directly connected to the actuator ground and cannot be used alone as feedback.

Maintenance and after-sales standards

Daily maintenance: The module is maintenance free and the ventilation openings need to be kept unobstructed; Cleaning can only be done with dry, lint free cloth, and the use of cleaning agents is prohibited.

Repair requirements: Only the manufacturer or its authorized engineer can carry out repairs. Unauthorized repairs will void the warranty.

Scrap disposal: After the module reaches the end of its service life, it can be returned to the manufacturer for paid recycling, and the manufacturer will handle and recycle it uniformly.

Warranty policy: According to the statutory warranty conditions, if the module is repaired/modified without authorization, the warranty will immediately become invalid.

Nameplate information: The module nameplate includes barcode, identification number, module model, order number, version, power supply voltage, production date, etc. When ordering, only the model/order number needs to be provided. When replacing the module, the software version can be read through the CNW tool and the project version can be reloaded.
