Description
The EMLC is a strain gauge amplifier: It converts an analog load cell with mV/V output into a digital one and can also be used on existing load cells to digitize an existing weighing system.
It is designed for IoT applications and is mounted either wired or directly to the load cell housing via a ¼-GAS connection.
The AISI 304 stainless steel housing is IP67 protected; 3 flying IP67 M12 connectors are included in the scope of delivery. Up to 4 load cells with 350 Ω can be operated in parallel using a junction box in 4- or 6-wire technology. The A/D converter operates at 24 bits and 16,000,000 digits at 4.8 kHz and provides 300 conversions per second; the measuring range is ±26 mV, the usable sensitivity is ±7 mV/V, and the linearity is < 0.01% full scale.
There are 3 relay outputs, 2 digital inputs, and a micro-USB port (type B, USB 2.0 full-speed) for configuration via PC software. Options include RS485, RS485 with analog output, IO-Link, CANopen, CC-Link, CC-Link IE, Profibus DP, Modbus/TCP, Ethernet TCP/IP, Ethernet/IP, Profinet IO, EtherCAT, POWERLINK, and SERCOS III. Power supply is 12 to 24 V DC at 5 W, and the operating temperature ranges from -20 °C to +50 °C. A CE-M version according to 2014/31/EU, EN 45501:2015, and OIML R76:2006 is available, with an alibi memory available upon request.
