GP4 supports SMS control, APP control, AI/DI with remote linkage actions. It supports 4-way relay output (10A NO&amp;NC), 4-channel digital input (dry-contact), and 4-channel current acquisition (4-20mA). It operates with a wide input voltage range of 9V to 24V. It is suitable for access control, building automation, and automatic industrial systems. <br />2. GP4-WLTE is a 4-channel DI/DO/AI 4G remote controller. The controller includes 4 channels of Digital Input (DI), Digital Output (DO), and Analog Quantity Input (AI). The DI supports dry contact detection; DO provides relay output with a control ability of 10A at 250VAC or 15A at 30VDC. The 4 channels of AI input support 4-20mA current input, with an accuracy of 12 bits. GP4 supports 2 control methods: APP and SMS. <br />3. GP4-WLTE is an IO controller that utilizes the 4G network for control. The primary control method is through the &quot;WLTE Control&quot; app, which can be easily found in the app market. This app allows for convenient parameter configuration and linking to the Digital Output (DO) relay for complex automation control logic. <br />4. Another control method involves using SMS, which can perform simple Digital Output (DO) control. Additionally, SMS alarms can be set. For instance, when the analog liquid level reaches the configured threshold, GP4 will send an alarm message to your phone. <br />5. Each of the 4 channels of relay output has an independent indicator, allowing immediate identification of the output state. GP4 operates within a working voltage range of 9-24V DC, making it well-suited for various industrial control environments. <br />Type:Smart 4G Controller <br />Model:GP4-WLTE (New Arrival) <br />All the kits include DC12V power adapter and external antenna.
