You can also review the different options when placing your order, prior to payment.

We handle three types of shipping:

SHIPPING 24/48 HOURS: 1 TO 2 DAYS

STANDARD SHIPPING: 7 TO 10 DAYS

EXPRESS SHIPPING (DHL): 3 TO 5 DAYS (POSSIBLE CUSTOMS COSTS)

Depending on the destination country and item type, all or only one or two shipping options may be available.

Delivery times are approximate and may be affected by specific or unusual times. A refund may only be requested if the item has not been received within 30 days of payment.

Orders with 24/48-hour express shipping are only for Spain. For international destinations, this type of shipping can take up to 7 business days.

Orders for lithium batteries or items containing batteries will take longer than usual due to a different delivery schedule. They may be delayed up to 30 days.

Orders over €180 or orders that select Express Shipping via DHL may be subject to customs fees in the destination country, which will be borne by the buyer.

In the event of rejection or non-acceptance of the order due to customs costs or fees, the order amount will not be refunded.

The default shipping company responsible for delivering orders will be Correos or DHL for Spain, or the postal service of each country. Deliveries may occasionally be made through other shipping companies.

Description

Characteristics:
1. This product is an industrial-grade 16-channel relay module controlled by RS485 bus, using Modbus RTU protocol, built-in power isolation, ADI magnetic isolation, resettable fuse, TVS diode and other protection circuits, and equipped with ABS shell.
2. The 16-channel Modbus RTU relay is very easy to use. Due to its high communication speed, stability, reliability and security, it is ideal for industrial control equipment and/or applications with high communication requirements.
3. Configurable device address (1-255), multiple devices can be cascaded on the RS485 bus
4. It has the function of flashing and blinking. By passing parameters to the command, the relay can open for a period of time and then close automatically.
5. Integrated on-board power isolation, providing stable isolation voltage, no additional power supply required at the isolation end
6. Integrated ADI magnetic isolation on board, which can realize signal isolation, high reliability, strong anti-interference and low power consumption.
7. On-board resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge and transient spike voltage in the circuit, provides overcurrent/overvoltage, lightning protection, anti-static
8. Built-in optocoupler isolation to prevent the relay from being interfered with by the high voltage circuit.
9. Built-in dedicated relay driver chip, built-in freewheeling diode protection, stronger and more stable driving ability
10. Anti-reverse connection circuit to prevent accidental damage to the circuit due to incorrect connection
11. High quality relay, contact rating: ≤10A 250VAC/30VDC
12. Rail-type ABS housing, easy to install and safe to use.
13. There are 3 LEDs to indicate the status of MCU and the status of sending and receiving signals.
Product parameters:
1. Working voltage: 5V
2. Communication interface: RS485
3. Baud rate: 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000
4. Default communication format: 9600, N, 8, 1
5. Broadcasting channel: 16
6. Contact information: 1NO 1NC
7. Communication protocol: standard Modbus RTU protocol
8. RS485 Address: 1-255
9. LED indicator light:
STA: MCU indicator light, keeps flashing when the MCU is working normally
TXD: TX indicator light, lights up when sending data
RXD: RX indicator light, lights up when receiving data
Packing list:
-Modbus RTU relay 16CH x1
-US Plug 5V 2A power supply (with EU head adapter) x1
