GM8802 Weight Transmitter
Introduction：
GM8802 Field Weight Transmitter is a single/multi-channel weight transmitter developed for industrial weighing field application. The transmitter is installed on site.
Applications: Widely used in concrete and asphalt mixing plant, feed, metallurgy, chemical ingredients and other occasions.
Features:
- On-site installation, dustproof and waterproof
- Built-in four-channel load cell terminal block (GM8802-D)
- 24-bit high precision two-channel, four-channel independent AD acquisition module (GM8802F-2/GM8802F-4)
- 16-bit high-precision DA analog module with resolution up to 1/65535 (GM8802-D)
- Analog supports current and voltage types, can be switched by modifying parameters, and supports customization (GM8802-D)
- Support GM protocol, standard ModBus RTU/ASCII and other protocols
- 32Bit processor for greater data processing
- Adopt special data package transmission mode, which increases the communication speed of single instrument by 2 to 4 times (GM8802F-2/GM8802F-4)
- With working parameter backup and recovery function (GM8802F-2/GM8802F-4)
