s【hgjmghhgf】GP4-WLTE Smart 4G Global GSM SMS APP Controller RS485 WEB Control 4 CH 4-20Ma Analog Inputs 10A Relay Outputs It supports 4-way relay output (10A NO&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.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 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.3. GP4-WLTE is an IO controller that utilizes the 4G network for control. This app allows for convenient parameter configuration and linking to the Digital Output (DO) relay for complex automation control logic.4. Another control method involves using SMS, which can perform simple Digital Output (DO) control. But no sensor. The measurement allowed error is +/- 1-3cm.Our store has stock in stock, please feel free to purchase and we will ship as soon as possible
