Feature:1. WIDE PROTOCOL COMPATIBILITY: The module supports a variety of protocols including but not limited to PLC, for Modbus RTU Master, for Modbus TCP Master, IEC101, IEC104, BACnet IP. For Cloud compatibility, it supports for Modbus TCP, MQTT, OPC UA, for AWS IoT, for ThingsBoard, for Sparkplug B, etc.2. RELIABLE AND FLEXIBLE POWER SUPPLY: The PLC module has a wide voltage design that supports DC 936V power supply. With its redundant design, it has two power input interfaces that can be selected with anti reverse protection.3. ADVANCED COMMUNICATION INTERFACE: The module supports 1 RS232 input and optional 3 RS485 RS232 inputs. The baud rate for the interface ranges from 1200bps to 115200bps with a choice of 1 or 2 stop bits, 7 or 8 data bits, and supports None, Odd, and Even parity modes.4. ENHANCED NETWORK CONNECTIVITY: This device has 2 RJ45 Ethernet ports, namely WAN and LAN ports, which can collect data from devices directly or from cascading switches. It has built in isolating transformers, and provides up to 2KV EMI isolation. It also supports 4G connectivity and can switch to 4G network when wired internet access is unavailable.5. HIGH SECURITY: The PLC board supports data TSL SSL encryption to guarantee data security. In addition, it is housed in a metal shell with IP30 protection level, making it suitable for industrial control applications. A RESET button is provided to restore factory settings to correct parameters settings errors.Specification:Item Type: PLC Control ModuleMaterial: Metal casing, electronic componentsBattery: 3.7V/900mAh lithium battery (shipped with built in battery)Power Supply: DC 9-36VPower Consumption: Normal: 115mA at. 12V, maximum: 168mA at. 12VEthernet Port:Details: 2 x RJ45, 10/100Mbps, adaptive MDI/MDIXProtection: ESD 16kV (contact), 18kV (air); EFT 40A (5/50ns); Surge 6A (8/20s)SIM Card:Quantity: 1Detail: Drawer type interface, supports 1.8V 3V SIM UIM cardProtection: Built in 15KV ESD protectionUSB Interface:Quantity: 1 for program download + 1 for program debuggingDetail: Small USB OTGProtection: Overcurrent protection.Package List:1 x Rail Clip1 x Main Unit1 x Card Eject Pin1 x Antenna3 x Screws1 x 4PIN Wiring Terminal1 x 12PIN Wiring Terminal
